I support progress on heat pumps and really wanted one.
I live in Calgary and wanted AC, had to get a new heater and water heater. We priced out the heat pump, and because of our cold winters would still need a furnace on top of the heat pump. Total quote was $26,000 and we still had to figure out how to fit it all to code in our tiny mechanical room. Getting quotes was like pulling teeth, the HVAC industry seems to hate them here.
Instead we got a new gas furnace, AC, gas water heater, auto water shut off valve with sensors and even the whole house pipes replaced for $14,000 total. The heater is so efficient that it will pay for itself in 3 years compared to the 20 year old one that was in here.
I don't have an analysis of electricity heat pump costs vs gas if we also had a heat pump. But even with the greener homes rebate it was not viable to get a heat pump yet. Maybe next time?
Yeah. Heat pumps are pretty shitty in Alberta. Even in Calgary with our chinooks, the cold snaps hurt them.
I've got a heat pump on my swimming pool. If I forget to shut it off at night, it turns into an ice cube the minute it hits about 12 degrees. They are a bit different than the heat pumps for houses, but having a heat pump in our winters isn't going to work. That much is clear. Like everything else, when they say it'll work till -30, it's really only good till about -5, then it'll have to pull so much energy to grab that heat out of the air, it's no longer efficient.
The idea is great, but I'm not sure they will be the ultimate solution in Alberta. Our altitude also has an impact on them too.
For sure. I lived in Penticton for a bit and the heat pump became more or less useless at around -10/-12, even down there. High efficiency gas is the best we have right now
