TL;DR: Water heater installation cost in Utah County as of 2026: $1,200-$3,500 for tank replacements, $2,500-$5,500 for tankless, based on industry estimates, including permit, haul-away, and code items (seismic straps, expansion tank, pan). Fuel changes, venting upgrades, and relocation push the top end.
| Install (industry est.) | Range |
|---|---|
| 40-50 gal tank, like-for-like swap | $1,200-$2,200 |
| 50-75 gal or power-vent tank | $1,800-$3,500 |
| Tankless conversion (gas) | $2,500-$5,500 |
| Heat-pump (hybrid) electric | $2,800-$5,000 |
| Add-ons: expansion tank / pan / strap | $150-$450 total |
Why do quotes for the same heater differ?
The unit is half the price; the rest is scope. Code items Utah inspections check, seismic strapping, thermal expansion tank on closed systems, drain pan in finished spaces, proper venting, belong in every honest quote. Fuel switches add circuits or gas line work; moving the heater adds plumbing; old-unit disposal and the city permit should be included, not surprises.
Is the cheaper quote actually cheaper?
Compare what is in it: a $1,100 swap that skips the permit, straps, and expansion tank fails inspection at resale and can void warranty coverage. Ask each bidder the same three questions, permit included? code items included? haul-away included?, and the spread usually collapses.
How do you keep the new heater alive?
In Utah County’s very hard water: start it softened, or commit to annual flushing, the same scale that killed the last unit is waiting for this one. Decision guides: tank vs tankless and gas vs electric; quotes at water heater installation or 801-874-8479.
