METHODOLOGY
To pick the best water heaters, we took into account a number of factors. These include:
- Price
- Size/Flow Rate
- Reliability
- 'Smartness'
- Ease of Installation
- Warranty
With the weighting in our methodology tilted heavily towards reliability, all of these factors all helped to build a picture of the best all-round model, as well as the best model in a variety of specific family and home circumstances.
OUR OVERALL WINNER
In a world of smart connectivity and ‘bells-and-whistles’ features, it’s easy to get daunted and distracted by the models on the market. After all, the fundamental job of a water heater is to heat water – everything else is peripheral. For that reason, the EcoSmart 27 stood out. Its simplicity breeds reliability – it is easy to use and doesn’t break down quickly.
Its flow rate at a 35 degrees F rise is 5.27 gallons per minute, which will have you more than covered for endless hot water for the whole house. It is also extremely eco-friendly which will benefit you by cutting your energy costs. According to the Department of Energy, this model will save you 50% on your water heating bills. Its lower price and strong warranty is what edged it out ahead of its electric tank competitors, but if you prefer tank heaters you can check out our best tank water heaters page.

What People are Saying:
“For myself, easy to install, though i knew what i was getting into. I purchased this to replace (2) 50 gallon tanks. I knew that i was going to need the (4) 40 Amp breakers and 4 lines of 8/2 wiring. Please make sure you have enough room in your power panels or hire an electrician to ensure this would be a good fit.” – Home Depot reviewer

What People are Saying:
“The noise is a non-issue. It’s about as loud as a vent fan over your stove, so if it’s in a basement or garage it’s not a problem. My sons playroom is in the basement and we are there most evenings and I can’t say I even noticed it in the background. Anyway, the fan doesn’t run all of the time. The compressor on top does most of the water heating for efficiency and the regular heating elements are for back up if using a lot of water.” – Lowe’s reviewer
