Electric Tankless Water Heater Buying Guide
There are many things to consider when shopping for an electric tankless water heater. Electric tankless water heaters are a great way to lower your water and electric bills while still enjoying a pleasant hot shower.
Unlike water heaters with tanks, they are very energy efficient, and they also are small and don’t take up much space. They only heat the water as needed, so you don’t waste energy. There’s also no limit to how much hot water you have, because it heats the water continually. Due to the small size, many people tend to use them as an under sink water heater too, which provide instant hot water and can be hidden within the cabinet.
However, since electric tankless water heaters are quite a large financial investment, you should always make sure that the one you are purchasing is of great value so that you can reap all these benefits.
If you are upgrading from an old conventional water heater, you may also qualify for a tax incentive by upgrading. This means you will be able to put some of this tax credit towards a better water heater. Here are the things you should look for when shopping for an electric tankless water heater.
The size of your electric tankless water heater is an important consideration to make when doing your shopping. Ideally, the water heater should be very compact so you can install it anywhere in your home.
This is particularly important if you are planning on installing it in a small space, like a bathroom or closet, or if you are planning on using the electric tankless water heater in your RV. Compact water heaters are also more aesthetically pleasing and won’t be an eyesore in your space. Look for a heater that has a sleek design that you like and will be happy to have in your home.
While not necessarily essential, a very helpful feature you should look for when shopping for an electric tankless water heater is a digital temperature display. This makes it easy for you to see exactly what temperature the water is and adjust it as needed.
There should be a knob or buttons near the display that make it easy to change the temperature. You should also consider the increments with which you can adjust the temperature. Ideally, you should be able to adjust it in increments of one degree or smaller for total control over your water.
Consistent Flow Rate
For the most comfortable experience showering or washing your hands, you will want to make sure that your water heater puts out water at an even rate. It’s also important that the water heater maintains the temperature, regardless of how much water is being used.
Some lower quality water heaters aren’t able to maintain their temperature when they get close to their maximum water output. The best quality water heaters are designed to ensure that this doesn’t happen, with flow control measures.
When looking at water heaters, the temperature output is something that can make a difference in your experience with it. The wider range of temperature outputs available, the more control you will have over your water. Some water heaters have potential temperature outputs as high as 140 degrees.
Ease of Installation
While all water heaters are going to require some installation, it’s important that the installation process isn’t too difficult or confusing. The water heater should come with instructions on how to set it up and where everything needs to be connected.
Ideally, the heater should be very easy to mount and attach as well. Some heaters even come with the cords and attachments you need to get everything set up, which adds even more convenience. If you are unsure what this process is going to entail, look up a how-to installation video on YouTube to learn more about what you will need to do to set it up.
The materials used in the electric tankless water heater you purchase should be very durable. Copper and stainless steel are common choices because they are incredibly long lasting. However, metals do come with some risk of corrosion.
Because of this, some companies are starting to develop water heaters that are made without any metal. This might be something to consider if you are worried about the quality of your water.
Every home has slightly different plumbing and electrical systems. Before purchasing a tankless water heater, it’s important to check your home’s specifications to determine what type of water heater you need.
In particular, you will need to look at the amperage and the kilowatts of output that the water heater has. You will also need to look at your home’s breakers and the required wire size of the heater, as well as the minimum water flow the heater requires in order to work.
Some water heaters can be quite noisy while they are working. This can be very irritating for you, the other residents in your home, and your neighbors. To avoid this, you should look for a water heater that operates silently. Technology is improving rapidly, and companies are figuring out how to develop water heaters that aren’t loud or clunky.
Inlet Water Temperature Requirements
The inlet water temperature is the temperature of the water that comes into your home. The inlet water temperature varies widely depending on where you live. You can look up the inlet water temperature for your area online.
Before purchasing your water heater, you will need to look at what the required inlet water temperature is for the specific product that you are purchasing. Ideally, the inlet water temperature requirement should be rather low, so that it will work well in both cold and warm climates.
An electric tankless water heater is a great investment for your home. It will allow you to take more comfortable showers without spending extra money on your electric and water bill.
Electric tankless water heaters may be a big investment up front, but they really pay for themselves over time. When shopping for your electric tankless water heater, use the features mentioned in this guide to ensure that you get the biggest bang for your buck.
