Connecting Geothermal To Water Heater

Normally we suggest a 600 ft coil in a 250 ft horizontal trench 6 ft deep per ton.

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. What you really need is an thermal engineer. Ghps can be factory equipped with desuperheaters or domestic hot water generators. In the cooling mode the ghp is taking heat out of the house and returning it to the cooler earth.

A geothermal heat pump heats your home using a compressor. 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. This is brilliant because this design can save energy and it can increase the output capacity of the tankless water heater. Here is my story.

This means the unit can generate up to 50 of your hot water at almost zero cost. A 2 ton unit would require two 250 ft trenches at 6 feet deep. 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. The compressor produces extra heat which is what we use to preheat your domestic hot water tank.

Best guess would be a 2 ton water to water unit. By passing this extra heat off to the dhw circuit in the ghp you get free hot water. For larger volumes of hot water water furnace also offers dedicated hydronic units. In an effort to remove propane from my life due to costs and.

The desuperheater harvests the extra heat using a pump and heat exchanger and deposits it into your electric hot water tank. 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. Geothermal heat pumps ghps take this process one step further if you know what to do.
