Water Heater Installation in Idaho Falls

We use First Hour Rating (FHR) calculations rather than simple tank gallon capacity alone. We factor in your household's peak morning or evening hot water demand—including simultaneous showers, dishwasher cycles, and washing machines—along with Idaho Falls' cold winter groundwater temperature (often 35°F to 40°F) to ensure your system recovers quickly without lukewarm spells.

The City of Idaho Falls Building Division mandates a plumbing permit for any new water heater installation or major alteration. As an Idaho licensed plumbing contractor, Idaho Falls Water Heater Pros pulls all required municipal permits, verifies electrical and gas code compliance, and schedules the final city plumbing inspection.

Under Idaho State Plumbing Code, when water is heated inside a closed plumbing system (such as one with a backflow preventer or pressure-reducing valve), it expands in volume by roughly 2% to 3%. Without an expansion tank to cushion this thermal expansion, the extra water pressure stresses tank welds, damages pipe fittings, and can cause the T&P relief valve to dump water onto your floor.

Yes. During basement finishing or home remodels, we frequently relocate water heaters into dedicated mechanical rooms or utility closets. We re-route cold and hot water copper/PEX manifolds, extend gas supply lines or 240V circuits, and install code-compliant direct-vent or power-vent piping to an exterior wall.

Our new Bradford White, Rheem, and AO Smith tank installations include standard 6 to 10-year manufacturer tank and parts warranties, along with our comprehensive 1-year local workmanship guarantee covering all labor, piping, and valve connections.
