Only a tankless one. Keller’s code does not permit water heaters in attic spaces, with the single exception of tankless water heaters.
Keller’s fee schedule lists a $100 plumbing permit for miscellaneous work such as a water heater when no building permit covers the job. The city only issues permits to registered contractors, so ask whether a quote includes it.
It depends on how many people use hot water at the same time, not only on the bedroom count. Keller households average 2.77 people, and 2.87 in owner-occupied homes, so we ask about peak use and give you a flat, upfront quote on a tank and a tankless option.
Only inside a sealed enclosure, so its combustion air does not come from the living space, behind a solid, weather-stripped, self-closing door. A direct-vent water heater does not need the enclosure, and a fuel-fired heater may not go in a room used as a storage closet.
Treat it as one. A leak from the tank body usually means replacement and can cause water damage fast. Shut off the water supply to the unit and call us; we offer same-day and 24/7 service, and in Keller the replacement cannot go back into an attic unless it is tankless.
