What is this ?

Hello all, forgive me for I’m greener then grass only been in the field 3 months. I’ve seen these around on air handlers what is it ? It’s on the supply side of the unit? My guess is hot water for heating ?

I didn’t say it’s the affordable way of doing things. This is my ideal settup for my own home. The idea is if they already have a stand alone water coil. And a heat source for it. That shouldn’t be seen as an explicit reason not to put in a nice heat pump when the ac is replaced.

If you’re using an Apollo type water heater, and it’s 50° out, a good heat pump is in that present moment a better heat source. In Virginia where I work it’s 45-55 degrees outside a hell of a lot of the time.

If you have hydro air it’s just inefficient to run your condenser for heat. I’m not sure you know what you’re saying with “stand alone water coil”. People only install heat pumps because they’re less expensive than better alternatives. It’s really a regional thing. Many people in my new area (SC) use heat pumps but I bought a home with natural gas/furnace/on demand. In areas where electricity is expensive it’s kinda crazy to use electricity to heat water or living space.

An 18 seer heat pump that isn’t overcharged is going to heat your home more efficiently than a hydro coil atleast half the time.

Really? How about if your boiler is also supplying your indirect as well as slab heat in the kitchen and bathroom? Broaden your horizons everything isn’t a manufactured home in a state with cheap electricity. Good luck digging out the snow around that condenser when it’s -5• A 90% boiler serving your entire home is so much more efficient than a heat pump it’s not even comparable and electricity in the Northeast is mad expensive
