i have a water furnace premier at. the pex in the floor is laid very close together so it wouldn't be a lot of effort to heat the space between the runs. i'm not so concerned about the investment amount to be honest, its more of a situation where we can't use gas as a fuel alternative for a boiler and the geothermal is already here. i have a manifold with 7 zone loops and my pipe is laid over by aprox 20 x 50 foot area.
no no, i'm not talking between the tubes. i'm just saying that there is little space between the tubes (about 8 inch) throughout the entire floor.
This statement perplexes me a bit:
"If you want to use the water furnace to heat water to run through the pex tubes it can be done by diverting some of the hot gas that currently runs to the central heating coil to a heat exchanger with that hot gas on one side of the heat exchanger, and the water in pex tube manifold, and fitting a water pump to move the water through the pex tubes?"
are you saying that its gas or gaseous matter that flows through the heating coil (copper tubes with fins that looks like a radiator) and not straight water? My understanding of the system was that water comes from tubes in the ground and that water is brought to temp by the constant ambient temp deep underground and that if that water isn't warm enough to heat the house when the fan forces air through the "rad" that the water flows through its assisted by an electronic heating coil that the air passes through before it makes its way through the ducts.
it also looks like that the system can draw from a slave tank thats connected inline with the houses domestic hot water tank for additional assistance, however at this time and ever since i've been here, the in and out valves to the tank have always been closed, so its not using any of that. let me know if that helps you any or if my understanding is totally out to lunch.
