When I put the addition on my house, I ran Rehau Pex to radiant heat the floor in two zones. The weather is mild in Seattle, so I haven’t hooked it into the hot water heater yet. The plumbing inspector said I should use my gas 40 gal. hot water heater as it would be adequate to heat my areas and provide hot water to the house. What I need is a a diagram of how exactly to hook the lines into the water heater and run them to a manifold and pumps. I’ve looked around for information on this and have come up blank and, sadly, the rough sketch the inspector made to direct me was lost long ago…
Does anyone out there have experience with this or perhaps ideas on how to do it? Diagrams or pictures would be helpful as I am a “do-it-yourselfer” and not familiar with lots of the technical terms.
