FAQ:

Q: Why choose a Natural Gas tankless water heater?

A: A natural gas tankless water heater is an efficient way to have a ready-supply of hot water on demand. The Rinnai RL series of tankless water heaters offers a great combination of value and efficiency.

Q: What are the top 10 tankless water heater brands?

A: So far, we have seen the tankless water heater brands Rinnai, Rheem, Takagi, Stiebel Eltron, Eemax, EcoSmart, and Sio Green. However, when drawing up a list of the top 10 models, we also considered several other water heater manufacturers.

Q: Which is better gas or electric tankless boilers?

A: The higher GPM of gas tankless boilers means they are better able to provide hot water to multiple appliances at once. On the other hand, if you’re looking for a point-of-use heater, such as one for your shower water or for a hot tub, electric will be sufficient.

Q: How much LP does a tankless water heater use?

A: LP heaters are similar to gas, but you’ll use one gallon of LP for every 3-4 gallons of gas, and they also burn cleaner with fewer emissions. Flow is measured in gallons per minute (GPM), and the flow rate of your tankless water heater is going to depend on both the specifications of your heater as well as where you’re living.
