My water heater, which is located in the attic, sprung a leak from it's drain valve last weekend after I drained it for sediment. The thing is on it's last legs and should be replaced soon, before it goes completely and dumps 40+ gallons of luke-warm water inside my house. I called a few plumbers yesterday to try and get an estimate of having a new water heater installed in the garage instead of the attic, or at least to find out the installation cost of tankless water heater in the attic. All of them told me they would have to see the house and I would have to pay for privilege of an estimate. Has anyone here had a water heater moved from the attic to the garage? Or had a tankless water heater installed in your attic? Is the cost reasonable or should I just get a new water heater put in above my head again?
