Connecting Geothermal To Water Heater

A geothermal heat pump heats your home using a compressor.

That might do what you need emphasis on might. In an effort to remove propane from my life due to costs and. I bought a house 2 years ago that has no access to natural gas and had propane for the hot water heater furnace and dryer. Ghps can be factory equipped with desuperheaters or domestic hot water generators.

A 2 ton unit would require two 250 ft trenches at 6 feet deep. Geothermal heat pumps ghps take this process one step further if you know what to do. Normally we suggest a 600 ft coil in a 250 ft horizontal trench 6 ft deep per ton. This is brilliant because this design can save energy and it can increase the output capacity of the tankless water heater.

By passing this extra heat off to the dhw circuit in the ghp you get free hot water. As a waterfurnace wshp unit runs it can capture heat that would normally go to waste and divert it to your water heater tank through an optional component called a desuperheater. With a ghp you can get a factory installed domestic hot water generator dhw generator or as the techies call it a desuperheater. Here is my story.

This means the unit can generate up to 50 of your hot water at almost zero cost. In the cooling mode the ghp is taking heat out of the house and returning it to the cooler earth. The compressor produces extra heat which is what we use to preheat your domestic hot water tank. The last few days i have been reading through the forums to try and find an answer but i can t figure out if a special water heater needs to be used with certain brands of geo systems.

With the tankless water heater in the system the heat pump and ground loop can be sized a little smaller which saves on purchase and installation costs. What you really need is an thermal engineer. Best guess would be a 2 ton water to water unit.
