Water heater blanket for furnace supply plenum?
We have several high efficiency gas furnaces. The furnace itself is
cool to the touch as are the insulated ducts. The only warm-to-hot part is the sheet metal supply plenum that is uninsulated. Since the furance is in our unfinished basement, it seems logical to insulate the plenum right? - Would a water heater blanket work well to insulate the plenum? - Any other suggestions for insultating material? (I know regular fiberglass batts are cheaper but I don't know if they are rated for contact with a supply plenum)? Also as a related question, we have a circa 2003 water heater who outside is barely warm to the touch (if at all). Would there still be any measurably signiicant benefit to wrapping it in a water heater blanket or is it already well insulated enough? Thanks! |

You can usually buy a roll at a plumbing supply. I have seen small rolls at Home Depot. |

Your ROI, return on investment is minimal for either of these in an unfinished basement. Heat rises. -- Colbyt Please come visit http://www.househomerepair.com |

True about heat risin but still the 5 sides (floors & walls) are uninsulated stone & concrete so doesn't heat radiate there too. Even if "most" goes up into the house, doesn't the rest go out? |

Heat also radiates downward and in all directions. A warm upstairs is still heating the downstairs, somewhat. Insulating the basement will reduce overall energy consumption. |

We are not tlaking insulating the loor between the basement and the main floor - we are talking insulating the outside walls of the basement - keeping the heat in. Thia way any heat lost by the furnace, hot water heater, duct work, etc - as well as heat lost through the floor, goes to heat the basement - keeping the floors warmer and reducing overal heating costs. |
