I have a small basement and am thinking of getting a tankless water heater. Are theyb reliable, cost efective and do they have to be put in a heated space? I have a large crawlspace that I could heat if that be the case. How much do they cost and can they work on PVC pipe? Are they easy to install?
My parents have one from Bosch and are very pleased with it. Beyond that, I don't know a whole lot, except that they need to be installed on an outside wall. I keep meaning to do more research, since my water heater's at an age where it could work for five more years, or could die tomorrow.
