Stiebel Eltron Tankless Heater

"The Stiebel Eltron Tempra 36 Plus Tankless Water Heater features exclusive Advanced Flow Control German patented technology invented by Stiebel Eltron to automatically maintain water temperature for constant comfort. It’ll reduce flow slightly if hot water demand exceeds capacity to ensure that hot showers will never be interrupted. Tempra 36 Plus will typically use 15-20% less energy compared to conventional electric tank water heaters. Although, it’s possible to save significantly more energy depending on personal home usage habits. The difference is that conventional tank water heaters continually store hot water, and as a result, lose 15%-20% of the total energy consumed to the environment around them. This is called standby heat loss. Tank water heaters that use gas or oil are even less efficient, because they also lose heat through their vents to the outdoors. Our tankless water heaters do not need venting, and will not store hot water, waiting for you to use it. They operate on-demand to provide continuous and endless hot water when you need it, and not waste energy when you don’t.

Best Water Heaters of 2022 Year

Buyer's Guide, Comparison and Advices

What to Look for in a Water Heater

Gas or Electric

The choice between an electric and gas-powered water heater depends on a number of factors, including local utilities and your own personal preference. Electric water heaters are favored by people looking for low upfront costs and households that aren’t set up with natural gas. While gas heaters are more expensive upfront, they can save you hundreds of dollars a year, depending on energy costs in your area.

Tankless or Tank

Tank water heaters keep a certain amount of hot water in a tank at any given time, ready to send to multiple appliances at once. Tankless water heaters quickly heat incoming water as you need it, and take up less space than a water heater with a tank. However, one unit may not be able to provide hot water to multiple fixtures at once, so you may need to buy multiple water heatersfor your home.

Tank Capacity

If you go the tank route, make sure that your water heater can store enough water hot to keep up with your family. While tank water heaters can provide water for multiple places at once, it will take longer to heat up new water than a tankless heater, which could leave you with an unexpected cold shower.

Best Water Heaters of 2022

Tank Water Heaters This most common type of water heater uses an insulated tank to heat and store water until it’s needed. Available in electric, liquid propane and natural gas models.

How to Determine Which Water Heater is Best for You

Gas vs. Electric

Gas and electric water heaters each have numerous advantages and disadvantages, but any comparison is complicated by additional myriad factors. If environmental sustainability is key for you, an electric water heater is the best option as electric units are much more efficient and don’t directly depend on fossil fuels to operate.

The cost of operating an electric water heater can be much higher than a natural gas water heater counterpart. In a power outage, a gas water heater will continue to run. Electric water heaters—especially Energy Star Certified ones—often offer federal and even state level tax credits which may save you money. These savings may not appear to be much at first, but run a careful calculation before buying—you may be surprised.

Tank vs. Tankless

Tankless water heaters require significant cost and labor to install and set-up, but the energy-savings in the long run can be well worth the expense. Tankless water heaters provide an endless supply of hot water which never sits in a tank that may pool or contain rust or sediment build-up. To learn more about tankless water heaters, check out our Best Gas Tankless Water Heaters of 2022.

 

Tank-style water heaters, on the other hand, are easy and inexpensive to install and can deliver hot water much more quickly than tankless water heaters. Tank-style water heaters also have a more consistent flow rate than tankless, which allows you to more consistently supply hot water to multiple appliances and taps at the same time—but not on endless supply.

Ease of Use

One final determination to make when selecting a new hot water heater for your home is in the ease of use for your new appliance. Many modern electric hot water heaters come with digital displays to help you monitor and control your hot water heater. Others may come with an app and be controllable via Wi-Fi. Still, others are smart home enabled and can communicate with your other smart devices, including Amazon Alexa (yes, you can talk to your water heaters now).

While these may not be your key choices when finding a new hot water heater, the extra functionality may be an important consideration to make your life easier down the road.

Water heater warranties

You might be tempted when shopping around for your water heater to make a decision based on features and price alone. But the importance of a good warranty shouldn’t be overlooked, as in a crisis, you’ll want to feel reassured you can get your home back up and running again. So, if you don’t want to be left without hot water for a long stretch of time, then pay close attention to a model with a strong guarantee. 

 

Typically, water heaters last from eight to 12 years, with their corresponding warranties usually covering six to 12 years. This does have a catch though, as labor warranties only tend to cover one year.

How many years does a hot water heater last?

When you’re spending so much at once for a hot water heater, the question of longevity is a concern. Fortunately, tank style water heaters generally last eight to 12 years on average – depending on if you have hard water in your area and perform regular maintenance to keep the heater running at peak efficiency. We found through our research and discussions with plumbing professionals that you can expect a new water heater to last for about 10 years. Setting aside a little money every year to help offset the cost for when you do have to replace it can help reduce the stress of forking over a chunk of change you weren’t expecting to spend.

 

We also found that many plumbing experts advise installing a hot water filter to help reduce the amount of sediment and minerals that get into your water heater. This extra system could help double the lifespan of your water heater, but we recommend consulting with your local plumber first to find out if it would be worth it in your area.
