Ever wonder what the most time consuming part of installing a solar water heating system is? Hands down it is the solar piping! Regular copper pipe requires high level of plumbing skills to carefully solder and run your copper. Once soldered the entire system needs to be flushed to remove the poisonous flux acid and then the system needs to be pressure tested. This is the easy part! Next the entire pipe system needs to be properly insulated. Not with cheap polyurethane foam but high temp EPDM foam. After this you then need to seal the insulation with either special tapes or tubing such that rain and sun won't damage the foam. Think your done? .... Wait you still need to run the temp sensor lines to and from the collector.
