Finding the Best Tankless Water Heater for Your Home

Here in Fort Collins, our homes face unique challenges. The cold groundwater in the winter means your water heater has to work harder, and our notoriously hard water can take a toll on appliances. These local factors are critical when you’re choosing a new water heater. A model that works perfectly in a warmer climate might struggle to keep up here. That’s why local expertise matters. We understand the specific demands of Colorado homes and can guide you to a durable, high-performance solution. This guide will help you navigate the options, ensuring the best tankless water heater for your home is one built to handle our local conditions with ease.

Key Takeaways

• Match the Flow Rate to Your Family’s Needs: Calculate your home’s peak hot water demand by adding up the gallons per minute (GPM) of appliances you might use at the same time. This ensures your unit can handle busy mornings without leaving anyone in the cold.
• Look Beyond the Price Tag to Long-Term Savings: A tankless model costs more upfront, but its superior energy efficiency and a lifespan that’s nearly double that of a traditional tank deliver significant savings on utility bills and replacement costs over time.
• Prioritize Professional Installation and Annual Maintenance: Proper installation is crucial for safety, performance, and protecting your warranty. To get the most out of your investment, schedule an annual flush to combat mineral buildup from hard water and keep your unit running efficiently.

Why Choose a Tankless Water Heater for Your Home?

There’s nothing worse than being the last one in the shower and feeling that water turn icy cold. If you’re tired of rationing hot water, a tankless water heater might be the perfect upgrade for your home. Unlike traditional models that keep a large tank of water hot 24/7, tankless systems heat water instantly, exactly when you need it.

This on-demand approach is the main reason homeowners make the switch. It means you get a virtually endless supply of hot water. You can run the dishwasher, do a load of laundry, and still have a hot shower waiting for you. As the experts at This Old House explain, tankless units heat water only when you need it, so you don’t have to worry about running out.

Because a tankless unit isn’t constantly working to keep 40 or 50 gallons of water hot, it’s also much more energy-efficient. This efficiency isn’t just good for the planet; it’s great for your wallet. You could see significant savings on your monthly utility bills over the life of the unit. Speaking of which, tankless models have an impressive lifespan, often lasting 15 to 20 years—a solid five to ten years longer than most traditional tank heaters. Their compact, wall-mounted design also frees up valuable floor space. If you’re looking for a modern solution that delivers convenience and long-term value, a tankless water heater is one of the smartest improvements you can make.

But after years of performing water heater installations across Fort Collins, we’ve seen which models consistently deliver on their promises. We only recommend brands that we’d be comfortable putting in our own homes—ones known for reliability, great performance, and solid customer support. Think of us as your expert filter. We’ve done the long-term field testing so you can choose a unit with confidence. Below are a few of the brands that have earned our trust time and time again.

Rinnai: The Industry Leader in Performance

Rinnai has built a solid reputation for a reason: their units are workhorses. They are known for exceptional engineering, long-term durability, and fantastic tech support if you ever need it. Many homeowners appreciate that Rinnai models often include smart features that make a real difference in daily life. For example, some units come with circulating pumps that keep hot water ready, significantly cutting down the wait time at the faucet. This not only adds a touch of luxury to your routine but also helps conserve water, which is always a plus.

Navien: Where Innovation Meets Efficiency

If you love smart technology and are focused on energy savings, Navien is a brand you’ll want to know. They are praised for their high-efficiency models, which often use condensing technology to maximize every bit of energy. In simple terms, this feature captures extra heat from the unit’s exhaust that would otherwise be wasted. The result is lower energy consumption and smaller utility bills. Many Navien units also come with built-in recirculation systems for instant hot water and Wi-Fi capabilities, allowing you to control and monitor your system from your phone.

A great warranty is more than just a piece of paper; it’s a manufacturer’s promise that they stand behind their product’s quality, giving you valuable peace of mind. Noritz units are also built to resist corrosion, which is a key factor in extending the life of any water-based appliance. For homeowners looking for a dependable, set-it-and-forget-it solution, Noritz is an excellent choice.

Key Features to Look For in a Tankless Water Heater

Once you’ve decided to go tankless, the next step is sorting through the options. It can feel a little overwhelming, but it really comes down to a few key factors. Understanding these features will help you choose a water heater that fits your home, your family’s needs, and your budget perfectly. Let’s break down what you should be looking for.

Flow Rate: How to Choose the Right GPM for Your Household

Flow rate, measured in gallons per minute (GPM), is probably the most important factor to get right. It tells you how much hot water the unit can produce at any given moment. If the GPM is too low for your household, you’ll end up with lukewarm water when the shower and the dishwasher are running at the same time. To figure out what you need, add up the GPM for all the fixtures you might use simultaneously. For example, a standard shower uses about 2.5 GPM and a dishwasher uses about 1.5 GPM. Together, you’d need a unit that can handle at least 4.0 GPM. We can help you calculate your home’s peak demand to ensure your new water heater keeps up.

What Do Energy Efficiency Ratings Mean?

One of the biggest draws of a tankless water heater is its energy efficiency. Unlike traditional tanks that constantly heat water, on-demand units only use energy when you need hot water. To compare models, look for the Uniform Energy Factor (UEF) rating—the higher the number, the more efficient the unit. We recommend looking for ENERGY STAR certified models, as they meet strict efficiency guidelines set by the EPA. Condensing tankless heaters are often the most efficient type available, capturing extra heat that would otherwise escape through the vent. This translates directly into lower monthly utility bills and a smaller carbon footprint for your home.

Gas vs. Electric: Which Fuel Type is Best for You?

Your home’s existing setup will play a big role in this decision. Gas models, which run on natural gas or propane, can heat water faster and support higher flow rates, making them ideal for larger families. However, they have a higher upfront cost and require professional installation for gas lines and ventilation. Electric models are typically less expensive to buy and easier to install, though some homes may need an electrical panel upgrade to handle the load. They’re also smaller and quieter. The trade-off is that they may struggle to keep up if you’re running multiple hot water appliances at once. Our team can assess your home’s plumbing and electrical systems to help you decide.

A Look at Smart Controls and Modern Features

Modern tankless water heaters come with some impressive tech features that add a layer of convenience to your daily routine. Many new models offer Wi-Fi connectivity, allowing you to control the temperature, monitor energy usage, and even receive maintenance alerts right from your smartphone. Another fantastic feature to look for is a built-in recirculation pump. This technology keeps hot water circulating in your pipes, so you get hot water almost instantly when you turn on the tap. It’s a simple upgrade that eliminates that frustrating wait for the water to heat up, saving you both time and water in the long run.

What a Warranty Reveals About Quality

A manufacturer’s warranty is a great indicator of a product’s quality and durability. A company that stands behind its water heater with a long and comprehensive warranty is confident that it’s built to last. Look for models that offer at least a 10- to 15-year warranty on the heat exchanger—the most critical component—and around five years on other parts. With proper care, a quality tankless water heater can last for 20 years or more, far outliving its traditional tank counterpart. Regular maintenance is key to reaching that lifespan, so a strong warranty provides valuable peace of mind for your long-term investment.

Tankless vs. Traditional: How Do They Compare?

Deciding between a tankless and a traditional water heater often comes down to weighing upfront costs against long-term benefits. While traditional tank heaters have been the standard for decades, tankless models offer compelling advantages in efficiency, lifespan, and space. Understanding how they stack up in key areas will help you figure out which system is the right fit for your home and family. Let’s break down the major differences you’ll want to consider.

Energy Savings: On-Demand Heat vs. Standby Loss

The biggest difference between the two systems is how they heat water. A traditional water heater is essentially a large, insulated tank that keeps a reservoir of water hot 24/7, waiting for you to use it. This constant reheating leads to “standby heat loss,” where energy is wasted just keeping the water warm.

In contrast, tankless water heaters warm water on demand. They only kick on when you turn on a hot water tap, using powerful burners to heat the water as it flows through the unit. Since they aren’t constantly using energy to maintain a tank of hot water, they are significantly more energy-efficient, which can lead to noticeable savings on your monthly utility bills.

Lifespan and Long-Term Value

When you invest in a major home appliance, you want it to last. Tankless water heaters typically have a longer lifespan, lasting around 15 to 20 years with proper maintenance. Traditional tank heaters, on the other hand, usually need to be replaced every 10 to 15 years as sediment buildup and corrosion take their toll.

While a tankless model has a higher initial purchase price, its extended lifespan combined with monthly energy savings often makes it a better long-term value. Choosing a quality brand and ensuring it’s installed correctly by a professional plumbing team can also reduce the need for repairs, adding to the overall savings over the life of the unit.

Space-Saving and Installation Flexibility

If you’re tight on space, this is where a tankless water heater really shines. Traditional models are bulky, taking up valuable floor space in a utility closet, basement, or garage. Tankless units are incredibly compact—often about the size of a suitcase—and mount directly to the wall.

This small footprint frees up a significant amount of room and offers much more flexibility for installation. A tankless heater can be installed in smaller, more convenient locations, including closets or even on exterior walls in some cases. If you’re looking to reclaim some storage space, switching to a tankless model is a fantastic solution. You can always contact us to discuss potential installation spots in your home.

Performance Differences You’ll Notice

The most celebrated benefit of a tankless water heater is the endless supply of hot water. You’ll never have to worry about being the last one in the shower and getting a blast of cold water. However, there is a trade-off to consider: flow rate.

While you get continuous hot water, a single tankless unit might struggle to keep up if you’re running multiple hot water appliances at the same time—like a shower, the dishwasher, and the washing machine. For larger families with high simultaneous demand, the solution might be installing a larger model or even a second unit. Our team can help you assess your family’s needs to ensure you get a system that performs perfectly for your lifestyle.

Which Tankless Water Heater Models Get the Best Ratings?

When you start looking at tankless water heaters, the number of options can feel overwhelming. The good news is that a few brands consistently earn top marks from both industry experts and homeowners. These models stand out for their performance, efficiency, and long-term reliability. Instead of getting lost in endless product pages, you can narrow your search by focusing on the brands that have already proven their worth.

Whether you need a powerful gas unit for a busy family or a compact electric model for a smaller space, there’s a top-rated option that fits the bill. We’ll look at some of the most trusted names in the industry, breaking down what makes them so popular and what real customers have to say about their experience. This will give you a solid starting point for finding a water heater you can count on for years to come. It’s about finding that sweet spot between innovative features, energy savings, and the simple confidence that you’ll have hot water whenever you need it. By focusing on brands with a strong track record, you’re not just buying an appliance; you’re investing in comfort and peace of mind for your home.

Top-Rated Gas Models for High Performance

For most homes in the Fort Collins area, gas tankless water heaters deliver the best performance and efficiency. Two brands that consistently lead the pack are Rinnai and Navien. Rinnai is often considered the industry benchmark, known for its incredible reliability and durable construction that’s built to last for decades. Think of it as the trusted workhorse that you can always depend on.

Navien, on the other hand, is celebrated for its cutting-edge technology and exceptional energy efficiency. Many of their models use advanced condensing technology and long-lasting stainless steel parts, which helps you save on energy bills. Plumbers often recommend Navien because its components are designed for longevity, making it one of the best tankless water heaters available today.

Top-Rated Electric Models for Smaller Homes

While gas models are more common, electric tankless water heaters are a fantastic solution for smaller homes, apartments, or as a point-of-use heater for a specific sink or shower. They are often more compact and can be easier to install in tight spaces. A popular name in this category is Eccotemp, which is known for its budget-friendly and user-friendly models.

These units are perfect if you have lower hot water demands or are looking for a supplemental heater for an RV or an off-grid cabin. While they may not have the same high-output capacity as a whole-home gas unit, they fill an important niche by providing on-demand hot water efficiently and affordably for the right application.

What Do Customer Reviews Say About Reliability?

When you’re making a big investment, you want to know that the product will last. Customer and plumber reviews are a great way to gauge a brand’s long-term reliability. Rinnai consistently gets high praise for its durability and excellent customer support, giving homeowners peace of mind. It’s a brand people trust to perform without issues.

Many professionals point to Navien as their top choice because of its smart design. Instead of copper, Navien uses a more robust stainless steel heat exchanger, which stands up better to wear and tear over time. Hearing that the pros trust a brand is a strong endorsement. If you want to discuss which of these reliable models is right for your home, our team is always here to help with our expert water heater services.

How to Size a Tankless Water Heater for Your Home

Choosing the right size for your tankless water heater is the most important step in making sure you’ll be happy with it. Unlike traditional tanks that hold a set amount of hot water, a tankless unit’s capacity is measured by its flow rate—how many gallons per minute (GPM) it can heat at once. This is a fundamental shift from thinking about a 40- or 50-gallon reserve. Instead, you’re calculating your home’s simultaneous hot water needs. If you pick a unit that’s too small, you’ll end up with lukewarm showers whenever someone starts the dishwasher, defeating the purpose of an on-demand system. A unit that’s too large is an unnecessary expense, both in the initial purchase and potentially in energy usage if it’s not a modulating model.

Sizing isn’t about the physical dimensions of the heater; it’s about matching its heating power to your household’s unique demands. It involves a little bit of math and a realistic look at your family’s daily habits. Getting this right ensures you have a steady, reliable stream of hot water exactly when you need it, without interruption. This process helps you avoid the frustration of an underpowered unit or the wasted cost of an oversized one. Let’s walk through how to figure out the perfect size for your home.

Calculate Your Home’s Hot Water Needs

First, you need to determine your home’s peak hot water demand. Think about the busiest time of day for hot water use in your house—maybe it’s in the morning when one person is showering, another is running the kitchen sink, and the dishwasher is on. Your goal is to add up the flow rates of all the fixtures and appliances you might use simultaneously. You can find the GPM for most fixtures printed on them. A standard showerhead is usually around 2.5 GPM, a bathroom faucet is about 1.0 GPM, and a dishwasher uses about 1.5 GPM. If you were to run all three at once, you’d need a tankless water heater that can handle at least 5.0 GPM. This calculation gives you a baseline for the minimum flow rate your new water heater will need to support.

Match the GPM to Your Family’s Lifestyle

Once you have your baseline GPM, it’s time to think about your family’s specific lifestyle. The number of people in your home and your daily routines play a huge role. A couple will have very different needs than a family of five with three teenagers. Do multiple people shower at the same time in different bathrooms? Do you often do laundry while running the dishwasher? Be honest about your habits. It’s always better to slightly overestimate your needs than to underestimate them. If your calculation comes out to 5.0 GPM, but you know there are times when the washing machine (another 2.0 GPM) might be running, too, you should look for a unit that can handle 7.0 GPM. This ensures that your hot water supply keeps up with your life, not the other way around.

Plan for Peak Hot Water Usage

Finally, you need to account for our Colorado climate. A tankless water heater’s performance is affected by the temperature of the groundwater coming into your home. In Fort Collins, our tap water is much colder in the winter, meaning the heater has to work harder to raise the water to your desired setting (usually around 120°F). This is called the “temperature rise.” A heater’s GPM rating is often based on a smaller temperature rise than what’s needed here. For example, a unit rated for 8.0 GPM in a warm climate might only produce 4.0 GPM during a Colorado winter. A professional will factor in local groundwater temperatures to ensure the model you choose can handle your peak demand on the coldest days. For larger homes, sometimes installing more than one unit is the best solution.

What Should You Expect to Pay for a Tankless Water Heater?

Let’s talk about one of the most important factors in any home upgrade: the budget. The total cost of a tankless water heater is more than just the price on the box. It includes the unit itself, professional installation, and any modifications your home might need to accommodate it. Understanding these different costs will help you make a confident decision that fits your finances and your family’s needs.

A Breakdown of Equipment Costs

The first number to consider is the cost of the tankless water heater itself. You can expect the unit alone to range from about $1,000 to $3,500 or more. This price difference comes down to factors like the brand, the model’s capacity (or flow rate), and its energy efficiency rating. Some of the best tankless water heaters on the market come with advanced features like smart controls, which can also affect the price. Think about which features are must-haves for your household versus nice-to-haves to find a unit that fits your budget.

Understanding Installation Costs

Installation is a critical piece of the puzzle and can significantly influence your total investment. Depending on the complexity of the job, installation costs typically run from $400 to $2,500. If you’re switching from a traditional tank heater, the process might involve running new venting, upgrading gas lines, or adding new electrical circuits. On average, a complete installation can bring the total cost to around $2,500, with more complex projects reaching up to $6,000. This is why professional water heater installation is so important—an expert can ensure everything is done safely and correctly.

Weighing Long-Term Savings vs. Upfront Cost

It’s true that the initial investment for a tankless water heater is higher than for a traditional tank model. However, the long-term savings can make it a smart financial move. Because these systems only heat water when you need it, they are much more energy-efficient. According to the U.S. Department of Energy, this efficiency can lead to energy savings of up to $100 per year. A comprehensive buyer’s guide will often point out that investing in a quality brand also means greater durability and fewer repairs over its longer lifespan, adding to your overall savings.

Common Questions About Tankless Water Heaters

Making the switch to a tankless water heater is a big decision, and it’s completely normal to have questions. While the benefits like endless hot water and better energy efficiency are exciting, it’s important to understand the practical side of owning one. Let’s walk through some of the most common questions we hear from homeowners in the Fort Collins area so you can feel confident about your choice. We’ll cover everything from performance and installation costs to the maintenance needed to keep your unit running smoothly for years to come, giving you a clear picture of what to expect.

Are There Flow Rate Limitations?

This is a great question because it gets to the heart of how these on-demand systems work. While a tankless heater provides a continuous supply of hot water, it can only heat a certain amount at any given moment. This is known as its flow rate, measured in gallons per minute (GPM). If you try to run a hot shower, the dishwasher, and the washing machine all at the same time, a single unit might struggle to keep up. For larger families or homes with high simultaneous water usage, the solution might be installing a single high-capacity unit or even two smaller units to ensure you always have the hot water you need, right when you need it.

Is Installation Complicated and Costly?

The upfront cost of a tankless water heater is typically higher than a traditional tank model, and the installation process can be more involved. Because these units have specific power and venting requirements, the job might involve upgrading your home’s gas lines or electrical panel to meet the demand. This complexity is why professional installation is so important for safety and performance. While the initial investment is greater, it’s helpful to view it as a long-term upgrade that adds value and efficiency to your home. For an accurate idea of what it would cost for your specific setup, it’s always best to get a personalized quote.

What Kind of Maintenance Is Required?

Just like any major appliance in your home, a tankless water heater needs a little TLC to perform its best. The most important task is to flush the system annually to remove mineral buildup, which is especially crucial with the hard water we often see here in Colorado. This descaling process prevents clogs and keeps the internal components working efficiently. You should also have the air and water filters checked and cleaned periodically. Following a simple maintenance schedule will protect your investment and ensure your unit has a long, productive lifespan. We can easily handle this for you as part of our regular plumbing services.

Setting Realistic Performance Expectations

So, what can you really expect after making the switch? The biggest and most immediate change you’ll notice is the continuous, on-demand supply of hot water. Long showers and filling a large bathtub back-to-back are no longer a problem—you’ll never have to worry about being the last one in the family to get a hot shower again. Beyond that convenience, you can also expect to see a reduction in your monthly energy bills, since the unit only heats water when you turn on the tap. These heaters are a fantastic, modern solution for homeowners looking for both performance and efficiency in their water heating system.

Installation and Maintenance: What to Know

A tankless water heater is a fantastic investment in your home’s comfort and efficiency, but its performance truly hinges on two key factors: proper installation and consistent maintenance. Unlike a traditional tank that you can often forget about (until it leaks), a tankless unit requires a bit more attention to keep it running smoothly for its full 20-plus-year lifespan. Getting the installation right from the start is non-negotiable. These systems are more complex than their tank-based cousins, often involving specific venting, gas line, or electrical requirements that absolutely need a professional touch to ensure safety and performance. An improper setup can lead to efficiency losses, error codes, and even void your warranty.

Once it’s installed, a simple maintenance routine will protect your investment and keep it delivering on its promise of endless hot water. Think of it like changing the oil in your car—a small, regular task that prevents major headaches and costly repairs down the road. Taking care of your unit ensures you get that continuous hot water you were promised, maintains its energy efficiency, and helps you avoid surprise breakdowns. We’ll walk through what you need to know about getting your heater set up correctly and keeping it in top shape for years to come, from the initial install to dealing with our local hard water.

Professional vs. DIY Installation

While the DIY spirit is admirable, installing a tankless water heater is a job best left to the pros. These units are complex and often require modifications to your home’s existing infrastructure. You might need to upgrade your gas line to meet the higher demand or run a new, dedicated electrical circuit. A licensed plumber and technician can handle these challenges safely and ensure your unit is vented correctly, which is critical for gas models. Getting a professional installation not only guarantees the job is done right but also protects your manufacturer’s warranty, which can be voided by improper installation. Don’t risk performance issues or safety hazards—let an expert get you set up for success.

How to Maintain Your Unit for Peak Performance

To keep your tankless water heater running efficiently for two decades or more, a little annual maintenance goes a long way. The most important task is flushing the system once a year to remove any mineral buildup, a service best handled by a professional. This process, also known as descaling, keeps the delicate internal components clean and prevents clogs that reduce water flow and efficiency. Between professional visits, you can help by keeping the outside of the unit clean and checking the air intake filter to ensure it’s free of dust and debris. This simple routine will help your heater perform at its best and extend its operational life significantly.

How Water Quality Affects Your Heater’s Lifespan

Here in Fort Collins, we have notoriously hard water, which can be tough on your plumbing and appliances—especially a tankless water heater. Hard water is full of minerals like calcium and magnesium that, when heated, form a crusty buildup called scale. Inside the narrow pipes of a tankless unit, this scale can accumulate quickly, restricting water flow and forcing the heater to work harder. This leads to lower efficiency and can cause premature failure. To protect your investment, pairing your tankless heater with a water treatment system, like a water softener, is essential. It will prevent scale buildup, maintain performance, and help your heater reach its maximum lifespan.

How to Find the Right Tankless Water Heater for Your Home

Choosing the right tankless water heater can feel like a big decision, but it doesn’t have to be overwhelming. Once you know what to look for, you can confidently pick a model that fits your home, family, and budget. The key is to move beyond the price tag and look at the features that will deliver reliable hot water for years to come. Think of it as an investment in your home’s comfort and efficiency. By comparing your options and getting some expert advice, you can find the perfect fit.

Compare Features at Different Price Points

As you start comparing models, you’ll notice a wide range of prices. Instead of just looking at the cost, focus on the value each unit offers. Key features to compare include the flow rate (measured in gallons per minute), which tells you how much hot water it can supply at once, and the fuel type—gas or electric. You should also check the unit’s Uniform Energy Factor (UEF) rating to see how efficiently it operates. A strong warranty is another great indicator of quality, as it shows the manufacturer stands behind its product. Make a list of these features and see how different models stack up to find the best balance of performance and price for your needs.

Is a Premium Model Worth the Investment?

It can be tempting to go with the cheapest option, but a tankless water heater is a long-term appliance. Investing a bit more in a premium model often pays off. Higher-end units are typically built with more durable components, which means they tend to last longer and require fewer repairs down the road. They also frequently come with better warranties and more responsive customer support. While a less expensive model might save you money upfront, you could end up spending more over time on maintenance and an earlier-than-expected replacement. Think about the total cost of ownership, not just the initial purchase price, to make a smart financial decision.

Get Expert Guidance from a Local Pro

Online research is a great starting point, but nothing beats personalized advice from a professional. A licensed plumber can assess your Fort Collins home’s unique layout, existing plumbing, and your family’s specific hot water demands. We can help you accurately calculate the flow rate you need and recommend the best fuel type for your setup. Consulting with an expert ensures you don’t overlook crucial details, like local water quality or venting requirements. If you’re ready to find the perfect tankless water heater, contact our team at JT Plumbing Heating & Air. We’re here to help you make a choice you’ll be happy with for years.

Frequently Asked Questions

How long will I have to wait for hot water to reach my faucet? This is a common point of confusion. A tankless unit heats water instantly, but it doesn’t change the time it takes for that hot water to travel through your pipes to the faucet. The wait time will be about the same as it was with your old tank heater. However, many modern tankless models can be equipped with a recirculation pump, which keeps hot water ready in the pipes, giving you nearly instant hot water when you turn on the tap.

Will my tankless water heater work if the power goes out? Even gas-powered tankless water heaters rely on electricity to power their electronic controls and ignition system, so they will not function during a power outage. If having hot water during an outage is a major concern for you, connecting your unit to a backup power source, like a generator or a battery backup system, is a potential solution to consider.

Is the annual maintenance really necessary, especially if it’s working fine? Yes, absolutely. Think of it as preventative care for a major investment. Here in Fort Collins, our hard water can cause mineral scale to build up inside the unit’s narrow passages, forcing it to work harder and eventually leading to damage. An annual professional flush, or descaling, removes this buildup, keeps the unit running efficiently, and is essential for helping it reach its full 20-year lifespan.

Can a tankless water heater really keep up with my family’s needs? It certainly can, as long as it’s sized correctly for your home. The key is to choose a model with a high enough flow rate (gallons per minute, or GPM) to handle the number of fixtures you might use at the same time. A professional can help you calculate your peak demand to ensure your unit can easily manage a shower, the dishwasher, and a load of laundry all running at once without any drop in temperature.

Are there any hidden costs I should know about besides the unit and installation? The main additional costs can come from upgrading your home’s existing systems to support the new unit. For a gas model, this might mean running a larger gas line to meet its fuel demand. For an electric model, you might need to upgrade your electrical panel to handle the power draw. A professional quote should always include an assessment of your home’s infrastructure so you have a clear picture of the total investment from the start.
