Remember the water heater must fit through the hatch to permit future change outs.
Gas hot water heater in attic.
Giant tanks of water happen to take up a lot of square footage and primarily for that reason many builders have opted to place water heaters in the attic of new homes.
Gas water heater the attic space should be appropriately ventilated especially during the summer as the outside temperature and humidity could increase to high values so the attic temperature will reach critical temperatures which will affect the correct working condition of the gas water heater.
As outside temperatures increase the need for proper combustion air and attic ventilation becomes even more critical.
As with all gas water heater installations it is very important to have sufficient combustion and dilution air to insure proper drafting of the exhaust products and safe water heater operation.
A water heater in the attic saves square footage tank type water heaters are big hulking cylinders filled with anywhere from forty to seventy gallons of hot water.
A transfer grille from the ceiling of the water heater room to another room of the house will allow combustion air to be pulled from conditioned space eliminating the flow of hot air into the attic in the winter and out of it in the summer.
