Parker asks a lot of a water heater
Winter nights here average 12°F from December through February, and homes need heat from October through May, eight months a year. A water heater in Parker runs through a long cold season, working alongside a furnace that's on for most of the year.
The federal minimum efficiency for storage water heaters isn't one number. It's a formula based on the tank's rated volume, applied separately across four draw patterns, so two tanks of the same type but different sizes can face different minimums. The right unit for a Parker home depends on its size and how the household uses hot water, not just what's cheapest to install.

A heat pump water heater would save about $280 a year to run in South Dakota compared with an electric water heater.

- How do I know it's time to replace my water heater?
- The clearest sign is water around the base of the tank. Once a tank starts leaking, it will not seal itself back up, and it usually means the tank has rusted through from the inside. Other signs worth acting on are water that never gets as hot as it used to, rumbling or popping sounds from the tank, and rusty water coming from the hot tap only. A tank water heater that is nearing the end of its typical service life and starting to show any of these signs is worth replacing before it fails outright, since a failure here means a cold house through a stretch of winter that runs from October to May.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on whether your current tank works fine. A tankless unit heats water as it flows through rather than storing a tankful, so you get continuous hot water instead of running out partway through back to back showers. It also takes up much less space than a tank. Against that, a tankless unit costs more to install than a like for like tank, and a contractor needs to check your gas line or electrical service can support it before you commit. A contractor can look at your house and your hot water habits and tell you whether it makes sense here.
- What changes when you install a tankless water heater?
- The biggest change is that you stop storing hot water and start heating it on demand. A tank keeps a tankful hot and waiting. A tankless unit fires up only when you open a hot tap, so you never run out but the flow rate at any one moment is limited by the unit's size. This usually means running a larger gas line or a dedicated electrical circuit, since the unit needs more power at the moment of use than a tank does. Venting changes too, since most tankless units need their own vent sized and routed for that unit specifically. A contractor will size the unit to your home's fixture count and water use before installing it.
