This is the outdoor unit.



This is the inside unit.

Our first month in service shows a 40% reduction in electrical usage compared to a year ago. That doesn't count the wood we were burning last year (over three cords).

So far it heats the 1400sf of our Solar Saltbox style home with painless remote control ease during our mild winters. The installer calculations say it is good down to 17ยบ F and we would then have to use the wood stove. It is much quieter than I expected it to be. The inside unit whispers (maybe 1/4 the noise of an electric fan type space heater). The outside unit makes a bit more noise (it has a larger fan).

Our installed cost for the heat pump and the electrical work was $4,893 and we will get a $1,200 rebate from the electrical utility (it cuts demand for peak power usage - their big expense).

It can be reversed in the summer to provide cooling.
None of us are as smart as all of us.

Aren't they amazing when it comes to operating noise? 

Cooling in the summer is very good too.  [cool]
Just because something has been done and has not failed, doesn't mean it is good design.
