@disk4mat You get lower than -30C (-22F)? you must be pretty far North for that.
I am in Calgary AB today is 35C .
@NorthernInvader I heartily agree! We have both a heat pump and propane furnace. It really helps us minimize how much we utilize the propane. We only fill our 500 gallon tank once per year. Our heat pump runs off of net zero solar, too! 😁 Electric bill is super economical, too.
@NorthernInvader
Our news was saying if you get a heat pump they are only good to 30 so have a gas back up.
