Questions & Answers

I was wandering which whole home tankless hot water heater I need. I have 2 bathrooms, washer and kitchen. live alone and seldem have overnight guest. Thanks Brad

Based on your supplied data, there is quite a range to be considered which will depend on the Gallons Per Minute(GPM) output of your faucets, shower heads, kitchen water usage and washer size. Ultimately, you can decide to operate using one unit, or install two smaller units depending on the layout of your residence. 

We recommend contacting a local contractor who specializes in tankless water heaters in your area that can properly calculate your Gallons per Minute usage.

As an electric application, the largest electric model that will potentially work is the Rheem RTE27 (click here to view) which will supply enough hot water for 5 GPM hot water flow, which will provide enough hot water for 2-4 fixtures at any given time in operation (or more if low-flow fixtures are used).

If the plumbing layout is wide, you may loose efficiency in the piping, and a second unit may be needed. A second unit is also recommended if you would like more than 5GPM of hot water flow.
