Backup generator for heat pump
I am building a new home in northern Minnesota that will be heated by a 7-ton geothermal heat pump. Given the unreliability of our electric power, a backup (NG-powered) generator would be useful, but I'm wondering whether anyone here has used a backup generator to power their heat pumps. The instantaneous draw (when the compressor starts) can be as high as 40 amps I'm told. How large (KW) a generator do you have?
Maybe the woodstove is a cheaper source of backup heat!
