Connecting Geothermal To Water Heater

The compressor produces extra heat which is what we use to preheat your domestic hot water tank.

Connecting geothermal to water heater.

With a ghp you can get a factory installed domestic hot water generator dhw generator or as the techies call it a desuperheater. This means the unit can generate up to 50 of your hot water at almost zero cost. A tankless water heater can be plumbed into the geothermal system to provide supplemental heat on the coldest of days to the water coming into the ground source heat pump. In an effort to remove propane from my life due to costs and.

A geothermal heat pump heats your home using a compressor. The desuperheater harvests the extra heat using a pump and heat exchanger and deposits it into your electric hot water tank. Here is my story. 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.

By passing this extra heat off to the dhw circuit in the ghp you get free hot water. In the cooling mode the ghp is taking heat out of the house and returning it to the cooler earth. For larger volumes of hot water water furnace also offers dedicated hydronic units. Best guess would be a 2 ton water to water unit.

Normally we suggest a 600 ft coil in a 250 ft horizontal trench 6 ft deep per ton. Geothermal heat pumps ghps take this process one step further if you know what to do. 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. A 2 ton unit would require two 250 ft trenches at 6 feet deep.

Ghps can be factory equipped with desuperheaters or domestic hot water generators. What you really need is an thermal engineer. 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.
