I replaced this Hydro-Temp combination heat pump this summer.

It is a dual compressor system, heats air and water (DHW and Radiant)

The radiant heat exchanger(plate style) was replaced once then the second one went.

The DHW coaxial heat exchanger was bypassed, may be OK, tech didn't do any serious tests for leaks, just a sniffer tool to a hyvent.

The final straw was the air coil started leaking.

There are some refrigeration tinkerers on here that could fix this thing up or use it for parts.

I am in Rhode Island.
