Chris, great and i love that you're working on this. We need more heatpumps in this world!
Any chance there's a solution coming for people with hydronic systems? We have a house in rural Ontario that has in-floor hydronic in the basement and hydronic radiators upstairs too. We'd love to get off propane, but there are virtually zero options without us installing ducts (which due to the German wood-frame design is very difficult to achieve without a lot of unfavourable cosmetic alterations)
There are air-to-water heat pumps, provided your emitters are sized such that you can heat your home with flow temps at/under 135°F. (I was able to test the prior winter and turning my aquastat way down and see when the house was no longer able to maintain the desired setpoint. For me, that was at about 9°F and it fell by about 1°F inside for every 2°F outside below that over a single night.)
If you can get by with 135°F (or ideally 130°F) flow, Google for "air to water heat pump" and there's likely a vendor that will sell into Ontario. (Ultimately, I decided against it for economic reasons, mostly because of a monopoly supplier in my area giving me a monopoly quote while not accepting Monopoly money.)
Interesting! I think upstairs we would struggle but the basement slab runs cooler, I’m pretty sure it would handle this pretty fine. I’ll check it out, thanks!!
