Air-to-water heat pump for hydronic heating–am I being realistic?
I’m looking to replace my direct hot water tank (8 years old) and gas boiler (45 years old) with an energy efficient system. My heat emitters are old convectors. It’s all monoflow piping.
Last year I got an estimate to get new rads + homerun manifold tied into a nice Viessman HE boiler and indirect tank. It was a little over $20k after my state’s rebates. I didn’t want to pull the trigger at that time because I didn’t have enough info to go for it.
After doing some more research, and thinking toward the future, I’d prefer an air-to-water heat pump with electric HE boiler backup (with new rads and manifold) plus electric hot water tied into this. I plan on getting a solar panels within the next 5 years when we get a new roof.
My state’s rebate for an Air to Water heat pump is $10k. I’d like to spend less than $30k prior to rebate, but I don’t know if this is even realistic. Before I dive deeper into planning what I’d like, does the Air-to-water heat pump system sound like it would be cost prohibitive?
Any perspective would be helpful.
