Installing Refrigerant Tubing to be Heat Pump Ready
I’m in construction on a small affordable housing 6-plex with one-bedroom units. The budget won’t allow for 6 mini-split heat pumps at this time so we’re doing electric cove heaters initially (pretty standard for affordable housing here in Oregon). We’re pre-wiring for a future heat pump retrofit but I’m also wondering if anyone has experience pre-installing the refrigerant tubing in the walls?
I’ve self-installed a heat pump before and the problem I’m seeing is what to do with the ends of the copper tubing at each end. From my memory we needed a foot or more of tubing protruding from the wall at each end to make the install, but this can’t be abruptly bent or rolled out of the way the way wiring can. Is it feasible to cut the tubing just behind a drywall access panel and have the future HVAC installer sweat/solder a connection here? And a similar approach at the exterior?
I’d love to propose a workable solution like this to the local heat pump store.
