Park City asks a lot of a water heater
Winter nights here average 12°F from December through February, and the incoming water runs cold with them. Add in that homes need heat from August through June, eleven months out of the year, and a water heater here is rarely working with warm ground water to start from.
The area also sees real weather. Ten years of records show 113 winter storms and 35 damaging wind events, and 7% of Utah households lost power for at least 24 hours in 2024. A new installation should account for what happens when the power goes out, not just how it runs on a normal day. On the efficiency side, the federal minimum for storage water heaters is not one number. It is a formula based on the tank's rated volume, applied differently across draw patterns, so two tanks of different sizes can face different minimums even if they are the same type.

A heat pump water heater would save about $320 a year to run in Utah compared with an electric water heater.

- How do I know it's time to replace my water heater?
- Look at the age first. Storage water heaters have a limited lifespan, and once yours is old, a repair now just delays a replacement later. Rust in the water, especially the hot side, means the tank itself is corroding from the inside, and that does not get better. A leak at the tank means the same thing, since these tanks do not develop leaks that seal themselves. Water heaters here run nearly year round, so a tank near the end of its life is working hard almost every month with little rest to slow the wear.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on your current tank being old. A tankless unit heats water on demand instead of storing it, so you do not run out during a long shower or back to back loads of laundry. It also takes up much less space than a tank. Whether it is worth switching comes down to your household's hot water use and your home's setup, and a contractor can walk through that with you for your specific house.
- What changes when you install a tankless water heater?
- The biggest change is that hot water no longer runs out. A tank holds a fixed supply and empties under heavy use, but a tankless unit heats water as it flows, so it keeps up as long as it is running. It also needs a larger gas line or a dedicated electrical circuit than a tank does, since it heats water instantly instead of keeping a tank warm all day. Venting is different too, and where the unit sits on the wall changes since there is no tank to work around. A contractor can look at your home's gas line, electrical panel, and venting to say what changes for your setup specifically.
