I was going to install a high efficiency gas boiler until a friend of mine showed me your work. You guys have done the hard part! Makes it easy to jump right in.

Yes, it's been a thought. I'm coastal, so not much variation in the seasons.

Water main is supplying 42*F right now. Last week the air was warmer, and this week its colder.

For my climate, being able to select between air or water would be the best.

I think final evolution will be both an air source evaporator and a ground source evaporator (likely water main). Put both on a common suction header. Each gets their own TXV and a solenoid valve on the liquid feed.
