Connecting Geothermal To Water Heater

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.

Connecting geothermal to water heater.

The desuperheater harvests the extra heat using a pump and heat exchanger and deposits it into your electric hot water tank. This is brilliant because this design can save energy and it can increase the output capacity of the tankless water heater. 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. Ghps can be factory equipped with desuperheaters or domestic hot water generators.

A geothermal heat pump heats your home using a compressor. This means the unit can generate up to 50 of your hot water at almost zero cost. With a ghp you can get a factory installed domestic hot water generator dhw generator or as the techies call it a desuperheater. That might do what you need emphasis on might.

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. In an effort to remove propane from my life due to costs and. Here is my story. 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. Best guess would be a 2 ton water to water unit. In the cooling mode the ghp is taking heat out of the house and returning it to the cooler earth. By passing this extra heat off to the dhw circuit in the ghp you get free hot water.

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. For larger volumes of hot water water furnace also offers dedicated hydronic units. A 2 ton unit would require two 250 ft trenches at 6 feet deep.
