I've looked through most of the forums and haven't seen this addressed: I recently had a Harman Accentra Pellet Stove installed in my home. It's heats the whole house, so my heat pump hasn't kicked on since we've had the stove(YES!![Fist pump]). My question is, is there a possibilty that the lack of use could damage the heat pump due to cold/snow/ice? Should I have the heat pump "kick-on" a certain amount of time in the week? The heat pumps(one for upstairs/one for downstairs) are at least 12 years old. Thanks.
