New House Choices

Going to build a 6200 sqft home in Eastern Tennessee.

Was looking at Geo Thermal but when calculating the theoretical cost savings vs. cost of unit installed, when calculating cost of money over that period, one would never recover the cost vs. that of a heat pump.

Have had in-floor heating before and wasn't too fond of it, mainly because we like carpeting and the room temperature was too difficult to control.

Are heat pumps still inefficient when the temp is in the 20s?

Not fond of gas, but if it is the only/best choice, then we'll likely look into it harder, although we'd have to have an underground tank since there aren't gas pipes in the area.

Given the above, what would be your recommendation for the best/efficient way to heat the house (also cool)?

Also, if you were going to have a heat pump system, would you prefer one large zoned system, or two smaller units. Any way to keep the compressor warmer in the winter?

Thanks for your thoughts.

Hello: hopro

To answer your heat pump question pertaining to efficiency during low outside temperatures is NO.

The operating principle is based upon the concept that everything has heat, therefore, nothing is really cold and that heat can be used. The problem is, temps of 20 degrees there isn't much heat to be drawn out of the air.

A home of the size mentioned, may need more then 2 heaters. The number of units depends on the floor plan, building materials, houses facing direction, etc. Energy wise, the idea is not to keep rooms heated that are unused during the sleeping hours of nights nor areas unused during the days, etc.

It's also a good idea to have multiple units to spreadout the heating load. This method offers several units which will not totally depend on only one heater for the square footage of a home the size your building.

Ultimately, the choice is yours.

I do not claim to be neutral nor unbaised. I can offer only my opinions, in this forum.

Regards & Good Luck
