Turning off HW heater while on vacation, lower T-stat or just leavepilot on?
I'm going away for a week and I wanted to put my gas HW heater in
"vacation mode". In the past I noticed that even if I turn down the T- stat dial, it still comes on, although the water temp is lower than the usual 140 deg. Am I better off just putting the gas valve to "pilot" instead of "on", that way I know for sure it will stay off? |

I also shut off the main water supply valve to the house as a precaution. Some people will argue that allowing the tank to cool down subjects it to stress and will result in earlier failure, but I've never seen that backed up by an actual data. Also, the temp swing from 130 down to 65 isn't that large compared to other temp changes with a lot of equipment that doesnt' cause failure. |

We had ours set to one-twenty but we've turned it down a bit from that after noticing that the "Vacation" setting was just about hot enough. When you think about it, if you have to add cold water to make your morning shower comfortable then why spend money to make the water hotter than you can stand in the first place? It's like driving with the parking brake on.... |

Well, not exactly. Most of the extra energy is not lost. If the water is hotter, you mix less of it with the cold to get the desired temp. That also means that you can take more showers at your desired temp before running out of hot water. The energy that is lost is mostly the additional amount due to standby losses at the higher temp. Most of the dishwasher manufacturers call for water that is at least 130. |

Well in all honesty, I don't know what the temp is, I just said 140 as a ballpark. But it probably is closer to 120 since I don't use a lot of cold water when taking a shower. |

A pilot flame uses a very small amount of gas while youre on vacation. |

Cut the main gas feed to it off and kill the power to it, if any. Can't be that hard to light. Maybe because for the ~10cents worth of gas it isn't worth the trouble. |

Most of the dishwasher manufacturers call for water that is at least 130. Dishwasers have their own heating elements so they can warm the water to whatever temperature they want. Dishwashers clean and (sometimes) sterilize just fine with cold water. In spite of what some might think, you should not add either bleach or fabric softener to a dishwasher. Some have a booster heater; I don't think all do. And most of those that do are intended only to boost ~20deg (from 120 to 140, allowing you to set the WH to the suggested scald prevention temp). I'm sure there are some with heaters designed to bring 40-50 degree water to 140, but they're rare. Our Frigidaire has a small display (it usually shows the time left, which is nice), but I'm always a little offended when it flashes "HO" at us while it heats the water :-) Josh |

Unless you need water pressure for sprinklers, turn OFF your water main, turn OFF the gas, turn OFF the water heater. When you turn your heater back on, follow the directions on the tank, it's usually quite easy. |

Its only a week the tank wont cool to room temp for maybe 3 days, id just turn it down. Be sure to turn off the water incomming main incase a pipe breaks, that can ruin a house in days. I used to leave for 3-4 days and turn off my tank, it was electric and still had maybe 80f water after many days. 140f costs alot more money than 120, I only heat my tank to what is needed for a hot water only shower. |

Pilot light models, leave the pilot light on at all times. I seriously doubt that this makes any difference. Turning off the pilot, even for a week, and the water won't even get down to room temp. Even if it does, it shouldn't be an issue. High efficiency water heaters and furnaces shut off the pilot themselves, and they don't have a problem. I suspect that the burning pilot could create more corrosion problems, as the resulting moisture from the pilot condenses on the cooler metal it can't really heat. |

Ours in located in the garage and the water is distributed through the attic. We live in Vegas and went away for 4 days so I turned it to the vacation setting.. We went came back, I forgot to turn it back up. We both showered and didn't notice for three days, since there is so much heat in the garage and attic during the summer here.

Even if you have a pressure regulator on the cold water input to your home, most of these have a back flow prevention....so if you use some hot water, then stop using water, all the spigots are closed. Then when the water heater comes on to re-heat the water, the pressure builds and cannot back flow through the regulator so it just builds and builds. And when you go away on vacation, the cycling on and off of the heater with NO use of water allows the pressure to build more then usual. So I always turn off the water heater when going away for a while just to keep the pressure from being able to build. The best answer is an expansion tank or pressure relief valve. I'm surprised this pressure build does not cause more problems then it does. Mark |

You're worried about the wear and tear of some valves (mine are all ball valves now and have never had to replace any of them) that probably only get exercised several time a year at the most. Low odds or not--how many catastrophic failures are you willing to put up with? Once is enough for me. BTW, how many faucet failures-kitchen, bathroom, etc.--have you experienced and over what time frame between them? Based on your comment, perhaps you ought to leave them on all the time instead of turning them on and off. With respect to the following comment: "What I do is turn the water heater down to the lowest setting and turn the water off to the house even if I'm gone for a night. It only takes me less than a minute" Now that is a potential catastrophe in the making. If you have an expansion tank, no problem. If you have a relief valve on your water heater (T&P Valve), no problem (if it works per design intent)--just some water on the floor. If there is no relief valve in the system (or it doesn't work properly) then you have a scenario that can result in a failure of the weakest link in your plumbing system----the water heater, a solder joint washing machine hose etc--. Water is not incompressible. It expands as it's temperature is increased--Example: Auto cooling system: every car today has an overflow tank to catch the coolant that comes out of the radiator as it is heated and expands. Almost all radiator caps are set to crack at 15 psi before they open. Without doing the math, increasing water temperature from room temp to about 140+F can increase the pressure of a closed system (no relief valve/expansion tank) to the 1000+ psi level. That's high enough to start breaking things. If you're interested: Delta P=BM*(Delta V)/V Whe Delta P is the change in pressure BM=Fluid Bulk Modules Delta V=Change in fluid volume (expansion as it heats up, can be calculated based on change of specific gravity vs temperature V=Volume of fluid in the closed system Granted, compressibility is not an everyday concern but it is an extremely significant factor in servo systems and can be the difference between a stable or unstable system.

The damage included furniture, walls, the ceiling below, etc. Now, he turns off the water main before vacation. |

"Phisherman" wrote in message ... On Sat, 22 Aug 2009 10:27:42 -0400, "MLD" My neighbor came back from a 4-week vacation with $34,500 damage due to an ice-maker line leak. The damage included furniture, walls, the ceiling below, etc. Now, he turns off the water main before vacation. I have a well and electric water heater. I always turn the breakers off when leaving overnight. This means I could get whatever is in the tank and no more water. Moved in this house about 4 years ago. The other house was fed by a comunity well and a gas water heater. It was built around 1965. The water pipes started getting pin hole leaks about 10 years ago. I had the pipes replaced after patching them about 5 times over a couple of years. After moving and while trying to sell the house I left the water on. Came in after being gone 2 days and found one of the hoses of the washing machine had broken and was leaking very bad. Just lucky it was a house where the washer was in the little room of a carport so there was no real damage done. I then cut off the water and turned the water heater to pilot unless I was at the house. |

I'm going away for a week and I wanted to put my gas HW heater in "vacation mode". In the past I noticed that even if I turn down the T- stat dial, it still comes on, although the water temp is lower than the usual 140 deg. Am I better off just putting the gas valve to "pilot" instead of "on", that way I know for sure it will stay off? Just put it on pilot. Mine's a power vent , and i just shut it off when we leave for more than 24 hours. 'Course the water gets shut off also. |
