How Does a Water Heater Loop Heat a Home in Chapel Hill?
What we found and did
Alex Clements replaced a 40 gallon natural gas water heater at a Chapel Hill home in the 27514 area and installed the loop system for the Apollo unit for heat. He put a checked valve on both the hot inlet and cold outlet, and installed a boiler drain on the hot side of the loop system to be able to get all the air out. Because the heater had to be turned up for the HVAC unit, he installed a mixing valve at the top of the heater to get the 120°.
