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.

Here is my story. This means the unit can generate up to 50 of your hot water at almost zero cost. 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. Normally we suggest a 600 ft coil in a 250 ft horizontal trench 6 ft deep per ton.

The compressor produces extra heat which is what we use to preheat your domestic hot water tank. A 2 ton unit would require two 250 ft trenches at 6 feet deep. What you really need is an thermal engineer. With a ghp you can get a factory installed domestic hot water generator dhw generator or as the techies call it a desuperheater.

A geothermal heat pump heats your home using a compressor. Geothermal heat pumps ghps take this process one step further if you know what to do. The desuperheater harvests the extra heat using a pump and heat exchanger and deposits it into your electric hot water tank. 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. That might do what you need emphasis on might. This is brilliant because this design can save energy and it can increase the output capacity of the tankless water heater. In an effort to remove propane from my life due to costs and.

Ghps can be factory equipped with desuperheaters or domestic hot water generators. Best guess would be a 2 ton water to water unit. 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.
