Here is my story.
Connecting geothermal to water heater.
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.
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.
Normally we suggest a 600 ft coil in a 250 ft horizontal trench 6 ft deep per ton.
For larger volumes of hot water water furnace also offers dedicated hydronic units.
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.
In the cooling mode the ghp is taking heat out of the house and returning it to the cooler earth.
Geothermal heat pumps ghps take this process one step further if you know what to do.
With a ghp you can get a factory installed domestic hot water generator dhw generator or as the techies call it a desuperheater.
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 means the unit can generate up to 50 of your hot water at almost zero cost.
What you really need is an thermal engineer.
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.
A geothermal heat pump heats your home using a compressor.
That might do what you need emphasis on might.
Ghps can be factory equipped with desuperheaters or domestic hot water generators.
In an effort to remove propane from my life due to costs and.
The compressor produces extra heat which is what we use to preheat your domestic hot water tank.
