  • Insulation?

    If an electric water heater is inside a living space where the highest temperature for the area will only be 50 degrees......does it need any insulation on it at all?

    Thanks.

    Not if you set the stat at 50 degrees.

        I would insulate the hot pipes so to help prevent heat loss.

          Why would it need any insulation? Why not just the raw steel tank?

          Thanks.

              don't the heaters already come with 1''-2'' of foam insulation under the outer shell?

              we have gas heaters that are required for new construction that are r18 insulated.

              electric heaters are similar, but i might only do 1 a year out here.

                I've found that if you wrap an electric heater in a cool climate that it condensates inside the jacket and corrodes the terminals

                    I was told not to add a blanket to the new water heaters with foam insulation under the TIN
                    I can build anything You want , if you draw a picture of it , on the back of a big enough check .

                      most likely due to the fvir air intake you would be covering

                          What would be the lowest temp that same area will go to? What is the stat temp set at?

                            This is nothing more than a hypothetical question as I sometimes am just thinking. So the lowest temperature is not known.

                            Just wondering if some places with cold environments (aka, low average temperatures) could somehow take advantage of the standby radiant heat loss from a tank.

                            Could maybe work. But there would probably be problems with temperature control.

                            Just thinking. Probably dumbly/dangerously.

                              I was reading a water heater insulation blankets instructions and it says to not block any air flow to the burner on gas models and on electric models to cut the blanket away from the electrical componets because it can overheat and deteriorate wiring. Thats a summary
