The only time the HP will shut off is in a case where you have a Dual Fuel system. HP with Gas backup.
Like I said. Some heat pumps have a balance point setting that WILL TURN OFF the heat pump and switch the first stage heat to the back up heat. Most applications electric strip heaters.
Which is inaccurate... you stated switching to electric strips. The only time you want to shut off the HP while the supplemental heat is on is when it's NOT backed up with electric.Originally posted by voleye
Some have outside thermostats that shut the pump off and switch to the electric heat at what is refered to as a balance point.
Otherwise you want the HP to continue to operate so you can save on operational cost, as it will always operate more efficient than straight electric strips.
At the prices he posted his ROI (Return on Investment) would warrant the electrical upgrade.quote:
With his cost of fuels, he'd be better off backing up the HP with electric strips.
But not if you have to run a heavier electric service to get 100 amps or so for the heat strips?
