These are common scenarios with traditional tank water heaters, but the best whole house electric tankless water heaters eliminate these woes forever. They heat water on demand, meaning you’ll never run out, no matter how many showers are running or how long you linger under the spray.
Think about the space a bulky tank water heater occupies – precious room that could be used for storage or other necessities. Tankless models are compact and wall-mounted, freeing up valuable square footage. Plus, they’re significantly more energy-efficient. Traditional tanks constantly heat water, even when you’re not using it, leading to wasted energy and higher utility bills. Tankless heaters only activate when hot water is needed, potentially saving you hundreds of dollars annually on your energy bills.
Beyond the immediate convenience and cost savings, consider the longevity. Tank water heaters are prone to corrosion and sediment buildup, requiring frequent maintenance and eventual replacement. The best whole house electric tankless water heaters are designed for durability and longevity, often lasting significantly longer than their tank counterparts. This translates to fewer repairs, replacements, and headaches down the road, making it a worthwhile investment in your home’s future.
Ultimately, upgrading to a whole house electric tankless water heater is about enhancing your lifestyle.

Sizing Your Electric Tankless Water Heater: Getting it Right
Choosing the right size tankless water heater is crucial. Imagine taking a shower on a cold winter morning, only for the water to turn lukewarm when someone else starts the dishwasher! That’s what happens when your heater can’t keep up with the demand. We need to ensure the unit can handle all your appliances and fixtures simultaneously.
The key factor is the flow rate – how many gallons of hot water per minute (GPM) you’ll need at peak usage. Think about running the shower, the kitchen sink, and the washing machine all at once. Each of these has a flow rate, usually listed on the fixture itself. Add those numbers up, and you’ve got a good estimate of your peak demand.
It’s better to err on the side of caution and go slightly larger than your initial estimate. This gives you some wiggle room for future additions, like a new bathroom or a high-efficiency showerhead that uses more water. Plus, it prevents that dreaded cold-water shock mid-shower!
Remember to consider the temperature rise you need. If your incoming water is quite cold, say 40 degrees, and you want to shower at 105 degrees, that’s a 65-degree temperature rise. A higher temperature rise requires a more powerful unit. Local climate plays a big role in determining the average temperature of incoming cold water.
Installation Considerations: DIY vs. Professional
Installing a whole-house electric tankless water heater is not the same as swapping out a light bulb. This is a project that involves electricity, plumbing, and a fair amount of technical know-how. You have to ask yourself honestly – are you comfortable working with high-voltage electrical wiring and connecting water lines?
If you’re a seasoned DIYer with experience in these areas, you might be able to tackle the installation yourself. However, keep in mind that you’ll need to ensure the unit is properly grounded, wired correctly to avoid electrical hazards, and plumbed without leaks. A single mistake could lead to serious problems or even void the warranty.
On the other hand, hiring a qualified electrician and plumber will ensure the job is done safely and according to code. They’ll know how to properly size the electrical panel, run the necessary wiring, and connect the water lines without any leaks. Plus, they’ll be familiar with local regulations and permits.
Think of it like building a deck. You could try to build it yourself, but a professional will know how to properly support the structure, ensure it’s level, and build it to last. The same goes for a tankless water heater – a professional installation can save you headaches and money in the long run.
Maintenance Tips: Extending the Life of Your Heater
Like any appliance, your electric tankless water heater needs a little TLC to keep it running smoothly for years to come. The biggest threat to tankless heaters is mineral buildup, especially in areas with hard water. Over time, these minerals can accumulate inside the unit, reducing its efficiency and potentially causing damage.
One of the best things you can do is flush your heater regularly, ideally once a year. This involves disconnecting the unit from the water lines and flushing it with a descaling solution specifically designed for tankless water heaters. The descaling solution helps dissolve mineral deposits and keep the internal components clean.
You should also visually inspect the unit periodically for any signs of leaks, corrosion, or damage. Check the water connections and electrical wiring to ensure everything is secure and in good condition. Addressing small issues early on can prevent them from turning into major problems down the road.
Finally, consider installing a water softener if you live in an area with hard water. A water softener will remove minerals from your water supply before they can reach your heater, significantly reducing the risk of buildup and extending the life of your appliance. Think of it as giving your tankless heater a protective shield against the damaging effects of hard water.
Understanding Energy Efficiency and Cost Savings
One of the main reasons people switch to tankless water heaters is the potential for energy savings. Unlike traditional tank heaters that constantly heat a large tank of water, tankless heaters only heat water on demand. This means you’re not wasting energy heating water that you’re not using. Imagine turning off a light in a room you’re not using to save electricity. A tankless heater does something similar.
The energy savings can vary depending on your household’s water usage habits. If you tend to use a lot of hot water throughout the day, you’ll likely see a more significant reduction in your energy bills compared to someone who only uses hot water sparingly.
While the upfront cost of a tankless water heater can be higher than a traditional tank heater, it’s important to consider the long-term cost savings. Over time, the lower energy bills can offset the initial investment. Plus, tankless heaters typically last longer than tank heaters, which means you won’t have to replace them as often.
To maximize your energy savings, make sure to choose a properly sized unit for your household. An oversized unit will waste energy, while an undersized unit won’t be able to meet your hot water demands. It’s a balancing act, but with careful planning, you can enjoy the benefits of energy-efficient hot water for years to come.
Your Guide to Choosing the Best Whole House Electric Tankless Water Heater
Hey there! Thinking about ditching that bulky tank and going tankless? Awesome! Switching to a whole house electric tankless water heater can be a total game-changer. Imagine endless hot showers, saving space, and maybe even lowering your energy bills. But, with so many options out there, picking the right one can feel a little overwhelming. Don’t worry, though! I’m here to walk you through the key things to consider, so you can confidently choose the best whole house electric tankless water heater for your home. Let’s dive in!
Flow Rate: How Much Hot Water Do You Really Need?
First things first, let’s talk about flow rate. This is basically how much hot water your heater can pump out at once, measured in gallons per minute (GPM). Think about your busiest hot water usage scenario. Are you running the dishwasher, doing laundry, and someone’s taking a shower, all at the same time? You need to figure out the combined GPM for all those activities to ensure your new tankless heater can keep up.
A good rule of thumb is to estimate the GPM for each fixture. A standard showerhead is usually around 2.5 GPM, a faucet is around 1-1.5 GPM, and a dishwasher or washing machine can be anywhere from 1.5-2.5 GPM. Add them up, and you’ll get a rough idea of the flow rate you need. Choosing a heater with a slightly higher GPM than your estimated peak usage is always a good idea to avoid any cold-water surprises. Figuring this out is essential when looking for the best whole house electric tankless water heaters.
Temperature Rise: How Cold Is Your Incoming Water?
Temperature rise is another crucial factor. This refers to how many degrees Fahrenheit your heater needs to raise the incoming water temperature to reach your desired hot water temperature. For example, if your incoming water is 50°F, and you want your shower water to be 120°F, you need a temperature rise of 70°F.
The colder your incoming water, the more powerful your tankless heater needs to be. In warmer climates, this isn’t as big of a deal, but if you live in a colder region, you’ll need to pay close attention to the temperature rise rating of the heaters you’re considering. Some manufacturers provide handy charts that show the GPM output at different temperature rises, which can be super helpful in making your decision.
Power Requirements: Can Your Electrical Panel Handle It?
Alright, let’s get technical for a sec. Electric tankless water heaters require a significant amount of electricity, so you need to make sure your electrical panel can handle the load. This means checking the voltage and amperage requirements of the heater and comparing them to your panel’s capacity.
Most whole house electric tankless water heaters require 220V or 240V and can draw a lot of amps, potentially requiring multiple dedicated circuits. If your panel is already maxed out, you might need to upgrade it, which can add to the overall cost of the installation. It’s best to consult with a qualified electrician before purchasing a unit. This can prevent future issues or even damage to your electrical system. Nobody wants to trip a breaker mid-shower! Properly assessing this is vital when considering the best whole house electric tankless water heaters.
Size and Installation: Where Are You Going to Put It?
One of the biggest advantages of tankless heaters is their compact size, but you still need to think about where you’re going to install it. Unlike bulky tanks, tankless heaters can be mounted on a wall, saving you valuable floor space. However, placement needs to consider accessibility for maintenance and proximity to electrical and plumbing connections.
Think about the existing plumbing layout and electrical wiring in your home. Will you need to run new lines? This can impact the installation cost. Also, consider the venting requirements. Although electric tankless heaters don’t require exhaust venting like gas models, you’ll still want to ensure there’s adequate ventilation in the area where you install it.
Energy Efficiency: How Much Will You Save?
One of the main reasons people switch to tankless is for the potential energy savings. Traditional tank water heaters constantly heat water, even when you’re not using it, which wastes energy. Tankless heaters, on the other hand, only heat water on demand, so you’re not paying to heat water that’s just sitting in a tank.
Look for heaters with a high Energy Factor (EF). This rating indicates how efficiently the heater converts energy into hot water. The higher the EF, the more efficient the heater. While the initial cost of a tankless heater might be higher than a traditional tank heater, the long-term energy savings can often offset the difference. Do your research and compare the EF ratings of different models to see which one offers the best energy savings for your usage patterns. This is often a deciding factor when deciding on the best whole house electric tankless water heaters.
Features and Technology: What Else Does It Offer?
Beyond the basic specs, consider the extra features and technology offered by different models. Some heaters come with digital displays that show the water temperature and flow rate, while others have remote controls that allow you to adjust the temperature from anywhere in the house.
Some advanced models even have built-in self-diagnostics that can detect potential problems and alert you before they become major issues. Descaling is essential for electric tankless water heaters. Look for a model with an easy descaling process. Also, consider models with safety features like overheat protection and leak detection. These added features can enhance your experience and provide extra peace of mind.
Warranty and Reliability: How Long Will It Last?
Finally, don’t forget to check the warranty and reliability of the heater. A good warranty can protect you from unexpected repair costs. Look for heaters with a long warranty on the heat exchanger and other key components.
Read reviews and see what other customers are saying about the reliability of the heater. Are there any common problems or issues that people have reported? Also, consider the brand reputation. Some brands have a proven track record of producing reliable and long-lasting tankless water heaters. Choosing a reputable brand with a good warranty can save you headaches and money in the long run. Carefully considering the warranty and reliability will help you find the best whole house electric tankless water heaters that will provide years of reliable hot water.
Okay, that’s a lot to think about, but you’ve got this! By considering these seven key factors, you’ll be well on your way to choosing the perfect whole house electric tankless water heater for your home. Happy showering!
FAQ
What exactly *is* a whole house electric tankless water heater?
Think of it like this: instead of heating a big tank of water and keeping it warm all the time, a whole house electric tankless water heater heats water on demand. So, when you turn on your shower or tap, the heater kicks in and warms up the water as it flows through. This means you’re not wasting energy heating water you might not even use, which can save you money on your electricity bill in the long run!
It’s designed to supply hot water to your entire house, unlike smaller point-of-use models that are meant for a single sink or shower. They are definitely an investment upfront, but their efficiency and endless hot water supply can be a real game-changer for busy households. Plus, you never have to worry about running out of hot water mid-shower ever again!
Are these tankless heaters difficult to install?
Okay, so here’s the honest truth: installing a whole house electric tankless water heater isn’t usually a DIY project unless you’re a licensed electrician or plumber. These units require a dedicated high-voltage electrical circuit and, often, modifications to your plumbing to handle the flow rate. Messing with electricity and water lines can be dangerous if you don’t know what you’re doing!
That being said, the installation process itself isn’t overly complicated for a professional. They’ll assess your current electrical panel, upgrade it if necessary, run the proper wiring, connect the heater to your plumbing, and ensure everything is working safely and efficiently. Getting a professional ensures it’s done right the first time and protects you from potential electrical or plumbing issues down the road.
How much electricity do these things actually use? Will my bills skyrocket?
That’s a really smart question! Whole house electric tankless water heaters do draw a significant amount of power when they’re actually heating water. However, the beauty of them is they use virtually no power when you’re not using hot water. Think of it like a light switch – it only uses energy when it’s on. So, while the instantaneous power draw is high, the overall consumption can be lower than a traditional tank heater.
To give you a better idea, consider your hot water usage habits. If you’re constantly running hot water throughout the day, a tankless model might not save you a huge amount. But, if you’re like most families who have peak usage times (mornings and evenings), you could see a noticeable reduction in your energy bills. It’s also worth considering the energy waste of constantly heating a tank of water even when you aren’t using it, which tankless avoids entirely.
Are there any downsides to electric tankless heaters?
Well, no product is perfect, right? One potential downside is the initial cost. Tankless heaters typically cost more upfront than traditional tank models, although they can often save you money over time. Another factor is the electrical requirements. As mentioned earlier, you might need to upgrade your electrical panel to handle the heater’s high power demand, which adds to the initial expense.
You also need to consider your water flow rate. If multiple people are using hot water at the same time (like running the shower and doing laundry simultaneously), you might experience a slight drop in water pressure or temperature. However, choosing a model with a higher flow rate capacity can usually mitigate this. The benefits often outweigh these drawbacks, but it’s important to be aware of them.
How long do these heaters typically last?
Here’s some good news: electric tankless water heaters are known for their durability! On average, you can expect them to last around 20 years or even longer with proper maintenance. That’s significantly longer than traditional tank heaters, which usually have a lifespan of around 10-15 years.
The longer lifespan is mainly due to the absence of a tank. Tank heaters are prone to corrosion and sediment buildup over time, which eventually leads to leaks and failures. Tankless heaters, on the other hand, don’t have these issues. Regular maintenance, like flushing the unit to remove mineral deposits, can further extend its lifespan and keep it running efficiently.
What size tankless heater do I need for my home?
Determining the right size is crucial for getting the most out of your tankless heater. The key factor is your “peak demand” – the maximum amount of hot water you’re likely to use at any given time. For example, if you often run the shower, dishwasher, and washing machine simultaneously, you’ll need a heater that can handle that combined flow rate.
A good starting point is to add up the flow rates of all the hot water appliances you might use at the same time. Most appliances have the flow rate listed in their manuals or on the unit itself. Then, consider the temperature rise needed. This is the difference between the incoming water temperature and the desired hot water temperature. A colder climate generally needs a higher temperature rise, thus a more powerful unit. Many online calculators can help you estimate the right size based on your specific needs.
What kind of maintenance do these heaters require?
The good news is that electric tankless water heaters are relatively low maintenance! The most important maintenance task is flushing the unit regularly to remove mineral buildup. Hard water can cause mineral deposits to accumulate inside the heater, reducing its efficiency and potentially damaging the components.
The frequency of flushing depends on the hardness of your water. If you have very hard water, you might need to flush it every six months. Otherwise, once a year should be sufficient. You can usually do this yourself with a descaling kit, or you can hire a plumber to do it for you. Also, periodically check the electrical connections to make sure they’re tight and free of corrosion. That’s about it! Regular maintenance will help keep your heater running smoothly for years to come.
