Fixing Bad Radiant

Attached is the fix for the open system that wouldn't heat the home or provide proper DHW. The Vitodens 222F cabinet model has a small footprint and a built-in 30g DHW SS tank. We used a larger FPHX to take the place of the low loss header. Pic 2 is the original system.

    Thanks. Flamco tank brackets. They make both non-potable and SS for potable. I found a neoprene insulation jacket made for FPHX's which will be installed. The exchanger puts out a lot of heat.

    Beautiful job (as usual.) I suspect you have another customer for life.

    Beautiful work as always. What was the problem with the old Uponor tubing that it needed to be replaced? Was it in floor or panel rads?
