West Bend asks a lot of a water heater
Winter nights here average 14°F from December through February, and homes need heat eight months a year, October through May. That's a long stretch where the water coming into the tank is cold and the heater has to work to keep up.
Power doesn't always stay on to run it. Wisconsin saw 18% of households lose power for 24 hours or more in 2024, and the county has logged 12 winter storms and 54 damaging wind events over the past ten years. A new installation should account for that. The federal minimum efficiency for storage water heaters isn't one number either. It's set by a formula tied to the tank's rated volume, applied across four different draw patterns, so the minimum for your household depends on the size tank you need.

A heat pump water heater would save about $330 a year to run in Wisconsin 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, since that means it's leaking and won't be repaired. Water that comes out rusty or with a metallic smell points to the tank rusting from the inside, which also means replacement rather than repair. A unit that can't keep up anymore, or makes popping and rumbling noises from sediment built up on the bottom, is wearing out. Most storage tanks last a good while, but once the tank itself is compromised, no repair fixes that.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on any rule that says you should. A tankless unit heats water as it flows through rather than storing it, so you don't run out of hot water partway through back to back showers. It won't heat water during a power outage any more than a standard electric tank would, so that's not a reason to switch. Wisconsin saw 18% of households lose power for at least 24 hours in 2024, so if backup during an outage matters to you, ask the contractor about that before deciding.
- What changes when you install a tankless water heater?
- The biggest change is that hot water doesn't run out, since the unit heats water on demand instead of drawing from a stored tank. It also takes up far less space, usually mounted on a wall instead of standing on the floor. Venting and gas line sizing are often different from what a storage tank needs, which is why this isn't a straight swap. A contractor can look at the house and say what needs to change to make the switch.
