How do I equate my current furnace capacity to that of geothermal heat pump systems? The sizes I see referenced for the GHP systems seem to relate to air conditioner capacities - 3-ton/4-ton/et cetera.

I am considering replacing my current gas forced air heat/air conditioner with a GHP system - and while I'm at it, considering including the heating requirements for my swimming pool. I know the up-front costs will be BIG (I just don't know how big yet).

Thanks in advance,
Bob

Anyone that is bidding on the job should run a heatloss and AC load on the home. This will tell you how many ton the unit should be. Now that pool I dont know??????? I have just use solar on the pools I have had, that was in Fl.

I'm just trying to figure out if this is even in the realm of feasibility, before I drag someone out to do a full analysis.

The pool guys have heaters rated at 200,000 btus and 300,000 btus (apparently, my pool falls somewhere in the middle and either would do the job, one just running longer). But I don't know how 300,000 btus compares to how many tons of GHP?

Im back to you have to run a load on the home to say what you need there. A BTU is a BTU but it dont work just that way here on a GEO set up.
A ton of AC is 12,000 btu. We have some homes with air to air heat pumps 4500sq ft 6 tons with back up electric heat.
From my past . You might want to keep the pool on its own set up for heat. It gets so they dont use the pool all year after a year or so. So it donr pay to heta and you can turn it off if you want .

Thanks. Appreciate your insights. I'll get somebody to do the analysis and figure it out.
