    water heater on or off-gctid731807

    Curious .......

    Whats the concensus over leaving your hot water tank and water pump turned on or off when you are leaving for the day say 8 hours or more ?

    More energy efficient to hold the temperature or to heat up the temperature loss over the day ?

    We turn off the water pump after each use. Just a habit.

    Water heater I leave off while away from the boat.

    Just what we have always done. No real reason. Just what we do.

      If I cannot leave my boats potable water system on, and the hot water heater on during a shore excursion, then I have a problem with my boat that needs to be fixed.

      If I am leaving the boat for more than a couple days then I'll shut off the HWH, more out of habbit and energy conservation than anything else. I also shut off the potable water but I have no reason to, because if I had a leak I'd of course fix it.

      I don't turn off the HWH and water pressure at home when I'm away, what makes a boat so different???

        I usually turn off the water supply and water heater when away from my boat for more than a day to save energy. The PO had a water line leak while they were away and it drained the water tanks into the bilge. No major damage, but it can happen.

        My home is 30 years old and I always turn off my main water valve and water heater when I leave. My neighbors on both sides have had substantial water damage when toilets have overflowed while they were gone for extended periods.

          Off and off.

          If something fails (known to happen) in your water lines the pump would empty your water into the boat. The hot water talk has a life span, why shorten it by leaving it on for no reason.

            I never leave the boat for a period of time without turning off the dock water supply and the on board water pump along with the HWH. Dock sid water supply left on can sink your boat.

                I am with Kevin. If I leave for me than a couple of days, everything gets turned off. If you are leaving for a few hours or a day, leave it on.

                I would think there would be more wear and tear heating it up from cold, rather than leaving it on.

                  Also, I never connect my boat to the shore water supply. For those that do, I definitely recommend that it be shutoff when leaving the boat.

                    Shut them off when not in use is a good policy. Along the theme of water heater has a definite life span, you can increase the life span by changing the anode rod in the heater every four or five years.

                          If we leave for the day fishing or whatever I turn off the pump. Not that 200 gallons will sink the boat but I wouldn't want to loose all my water.

                          I connect to shore water when I'm at my home dock. I always turn it off at the dock even If I'm only going to be gone a couple hours.

                          I had a refer ice maker line break in a rental in Phoenix. It ran for a month before our gardener called to tell us water was coming out of the side of the house. It wiped out 4 rooms including the kitchen. Lesson learned.

                            A hot water heater and full fresh water tank is the same displacement whether it is on board, or if it has leaked into the bilge. If it has leaked into the bilge then the bilge pumps should handle it.

                            The point is, the amount of water in the fresh water tank and water heater will not sink the boat.
