We have a 1930's era home which we bought this summer. We've noticed that it takes FOREVER to get hot water to any of the fixtures, even many of the basement fixtures closest to the heater. I hate wasting so much cold water. We have lots of pressure, even on the third floor of the house, and once the hot water comes it is scalding. I'm wondering if this is simply attributable to insulation and plumbing lengths, or if the water heater itself is in any way responsible? I'd like to stop wasting so much water but am not sure where to start. I don't even know which type of contractor this would come under (plumber? insulation? gc?). Any advice would be greatly appreciated.
