I'm amazed at these prices, I replaced a propane tank + furnace with horizontal loop ground source for $40k Canadian (+ tax, but government rebate matched that). It's almost paid for itself in about 6 years, I gave more detailed numbers in another reply.

Your setup sounds great, but depending on location in Canada, gas can be much cheaper than propane. I just priced running a gas line for my BBQ, and I'd break even on a $500 install cost after about 40 20lb propane tank fills.

Yes the calculations are different for natural gas, I don't have that option. Rural properties here (south/central Ontario) typically use delivered oil or propane supplemented by firewood.

I recently thought about running a BBQ gas line from my main 500 gallon propane tank, but with delivered propane close to $1/litre right now and a 20lb tank holding about 18 litres there's no saving over just using with the portable tanks. I prefer being able to move the barbecue around too, although I probably would run a line if I had an outdoor kitchen type setup.
