Adding Another Heating Zone
Hi, looking to add a zone to my heating system. I currently have a propane boiler with four zones, 1) HWT 2) Air exchange 3) infloor in garage and I want to add infloor under joist throughout the main floor. My question is, once the pex is installed underfloor, what is best to reflect the heat upwards? Plates or insulation or both? The house has a crawl space 4-ft. and main is approx 1300 sqft.
