Who doesn’t want a Tankless water heater these days right? Tankless water heaters last nearly twice as long as the contemporary water tanks. So we have compiled together a list of the top ten Tankless Water Heaters, rating them according to their price and quality as a whole.

10. EcoSmart 18

It is a 18kW 3.5 GPM Electric Tankless Heater. The best thing about this one? It comes with a lifetime warranty! You can easily install this heater indoors and the features include a self-modulating technology apart from a digit temperature control which allows you to set the temperature precision of nearly 1 degree. It is perfect for apartments with up to 3 people. Moreover, you can be guaranteed of coverage for the entire time you are at your home.

9. EcoSmart 36

Apart from high energy savings and high flow rate, this electric Tankless Heater might be ideal for you. It measures just  17 x 19 x 3.8 inches and weighs just 17 pounds, thus ensuring you can place it anywhere, even inside some old storage closet, you never bothered opening for a long time. It is easily one of the smallest electric tankless water heaters which are still fully capable of an impressive power.

According to Ecosmart, this heater is about 90 percent smallest than the standard ones in this range. Moreover, it doesn’t even require vents to function.

8. Rheem RTE 13

Capable of delivering a 4 GPM at 240 Volts, the RTE 13 is a small but efficient electric heater that can be installed into any small sized space. With such capacity it might just be enough for several people showering simultaneously, therefore there is no need to worry, about ending up with cold water. But there is a downside to this small size that for larger homes, it simply wouldn’t be enough.

Moreover, it won’t be suitable for extreme temperatures, since the 4 GPM is for ideal conditions, and can easily drop down to 2 if your usage is a lot. But the best and most attractive thing is the price; it is relatively very inexpensive and best suitable for a small home.

7. Takagi T-KJr2-IN-NG

The only setback would be that since it runs on natural gas, you will to have to require proper venting done since fumes need to expelling continuously so as to avoid building them up in the place you reside. Though it’s not at all dangerous as it may seem, but certainly but proper venting would certainly add up the cost as well as require time.

6. Rinnai RL75iN

This natural gas unit might have some quality issues, but with a uniform energy factor of 0.81, it would largely amount to savings. Moreover, with a maximum domestic hot water flow rate of 7.5 GPM, you need not worry about running out of hot water in between multiple showers are being serviced.

Furthermore, it is amongst the few models that can be converted to propane. The best thing is it is Wi-Fi compatible so can be controlled wirelessly.

3. Takagi T-KJr2-IN-LP
