Combi Replacement

There are many installations of new, open systems using a 50g water tank and radiant in Seattle. There's also a lawsuit proceeding to make corrections, as the original Plasco tubing suffered UV failure, having been left out in the sun for several months. We've replaced 4 systems in one condo so far, and I'm told there's over 6000 units with similar systems.
The Combicor replacement uses an auto feeder with RPZ backflow protection. I can't expect the appliance to last more than 5-10 years, but at least the system is protected from potable contamination. Also tried the new Simplex ball valve/thermometers. Neat!!
