Geothermal and water heater selection
Hi, I am in the process of building a new home that will have geothermal heating and cooling. Of course one of the benefits of geothermal is "free hot water." My geothermal installer is recommending two hot water heaters.
There will be no hot water on days the unit isn't running. My question is, should I buy two 85 gallon Marathon Water heaters from my local power utility for $918.06 (includes tax), or should I just buy standard water heaters?
My goal is to be as energy efficient as possible while not breaking my wallet.
