My "day job" is as maintainance super, at a country club. We have 38 heat pumps. They are water source pumps, with a boiler, a cooling tower, a plate type heat exchanger, two 750 gpm circulation pumps, and a ton of controls.
With all that, the individual heat pumps work very much the same as the "air to air" pumps that are used in residential systems. The only difference is ours are more efficient. (Due to a constant temperature water supply, as opposed to variations in the ambiant air temp. that you deal with on air to air)
OK, my point is, the ones we deal with work better than normal residential units. And they still don't do such a great job.
With outside temperatures of below 30 degree's, or above 95 degree's, they struggle.
(Granted, some of that is becouse our 98 year old building isn't as well insulated as it should be)
Heat pumps are great in theory. They work at a low cost MOST of the time. The bulk of the units I have dealt with, in home use, require suplimental heat (Usually electric strip heat in the ductwork). There goes all the "gains" that you made in "savings" with the heat pump.
I have one "full time" tech, that does nothing but service the equipment in our building. He has almost 30 years of experience in the HVAC field. He is building a new house at this time. So am I. With more background in the field of HVAC than the average individuals, we are BOTH going with gas, forced air heat,then using conventional air conditioning. My "tech" lives in an urban area. He will have "city gas" (Natural gas). I am building on our farm, which is WAY OUT in the boonies. I will use propane. It's not cheap, but niether is letting your electric heat, or your heat pump run continuously, throughout the colder, and hotter months.
Bottom line. Heat pumps may be a little less expensive to operate, but they aren't that much less expensive to install. And when you're all done with the "install", you will have a much more "consistantly comfortable" home with the gas system.
JMHO, John
