What Whatcom County winters ask of a water heater
Winter nights here average 27°F from December through February, and homes run their heat all twelve months. A water heater installed here works through that cold every year, not just for a few weeks.
The federal minimum efficiency for storage water heaters is not one number. It is a formula based on the tank's rated volume, applied separately across four draw patterns, so two tanks of different sizes can face different minimums even when they are the same type. A licensed installer will confirm which minimum applies to the size you need before it goes in.

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

- How do I know it's time to replace my water heater?
- Age is the first thing to check. Most tank water heaters last around a decade, so if yours is getting up there, a repair may just delay a bigger failure. Rust colored water from the hot tap, water pooling around the base, or a tank that's making rumbling or popping sounds are all signs the tank itself is wearing out from the inside. A tank that can't keep up, one that runs out of hot water faster than it used to, points the same way. If the tank is leaking, that's not a repair, that's a replacement, since a leaking tank won't seal back up.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on any rule that says tankless beats tank. A tankless unit heats water as it flows through instead of storing it, so you don't run out of hot water partway through a long shower or back to back loads of laundry. It also takes up less space than a tank. Switching usually means changes to the gas line, venting, or electrical supply, since tankless units have different demands than the tank they're replacing. A contractor can look at your home and tell you what that switch would actually involve.
- What changes when you install a tankless water heater?
- The water heater stops holding a reserve of hot water and starts heating it on demand instead. That means no standby losses from a tank sitting full of hot water all day, but it also means the unit needs enough gas or electrical capacity to heat water fast, right when you turn on the tap. Venting is usually different too, since a tankless unit vents differently than a standard tank. The install often means new venting, a bigger gas line, or upgraded electrical, depending on the unit and the home it's going into. A contractor can tell you which of those changes your house needs.
