A idea about geothermal heating & cooling


Is this kind of thing suitable for DIY? It sound really simple. So just replace the air source condenser with coaxial condenser, dig the wells, pump water through the condenser?

BTW, approximately how much will the coaxial condenser cost for a 5 ton heat pump?

You could do the change out of the condenser coil to coaxial.

But you would need a HVAC tech to do your recovery and recharge.

Don't know what the cost of a coaxial would be, haven't priced one out for replacement lately.

Doesn't the control circuit need to be modified? For example, the defrost mechanism. There may also be a meter that adjust the pressure according to the outside temperature. When groundwater is used, should it measure the temperature of the groundwater instead?

I also read from somewhere that the air handler need to be matched to the heat pump. Does changing the condenser bring the need to also change the air handler?

Lots of things would need changed.

Better off just buying a self contained geo/water sourced heat pump.

Wow. This is exactly what I'm talking about. I firmly believe that this is something I'd be able to pull off. But I probably won't do it because I may have to change it back or buy and install a new heat pump when it comes to reselling my house. I can't count on the next owner to be able to work with the monster I would have created.

BTW, when people say the air handler need to match the heat pump, they mean to match in what respect?

Tested/rated to work with the condenser/outdoor unit.

A 3 ton Trane condenser is not a match for/to a 3 ton Rheem air handler.

Can the coaxial condenser be matched to the air handler by adjusting the flow rate?

Are you talking the coaxial condenser only, or a water sourced condenser.

All condensing units/pieces, must be matched for the total heat transfer of the indoor unit.

I was referring to coaxial condenser. I mean do you have to do ask an HVAC or geothermal expert to help you buy a coaxial condenser that matches the air handler, or you can buy a coaxial condenser based on the tonnage and operating pressure and work out the optimal flow rate that matches the air handler.

You have to buy it based on your heat sink/heat source.
