Top tankless models to buy
Rheem RTGH 95
Best tankless water heaters are designed with two heat exchangers that make the condensing technology possible, providing ultra-efficient water heating for the highest energy savings.
The largest and most advanced model from Rheem is tankless water heater RTGH-95DVLN that has the highest efficiency of 0.94 and a water flow of 9.5 GPM, making it ideal for homes with up to 4 showers. Its secondary condensing heat exchanger is made of durable and strong stainless steel. As it is Energy Star compliant, the unit easily qualifies for different incentives.
This tankless model is equipped with the remote controller for convenient temperature set up, EZ-Link to connect two units for higher hot water demand, and the option to manifold up to 20 units. The hot start programming reduces the temperature fluctuation and "cold water sandwiches," increasing comfort.
Good alternatives to the above model are RTGH-90DVLN and RTGH-84DVLN both built for houses with up to 2-3 bathrooms and water flow of up to 8.4 GPH, utilizing the same advanced features as mentioned above, but with the lower power.
Either one you choose, the tankless models are equipped with several safety elements making them well protected from extreme conditions (high temperature or freezing), and also backed by the 12-year factory warranty.
