What a Stevens Point winter asks of a water heater
Groundwater coming into the house is already cold before your water heater does anything with it. Winter nights here average 10°F from December through February, and the house calls for heat nine months of the year, September through May. That is most of the year spent asking more of a tank that has to bring incoming water up to temperature, not less.
Power is part of the picture too. Wisconsin saw 18% of households lose power for 24 hours or more in 2024, and Portage County has logged 27 winter storms and 44 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps making hot water through an outage. One that depends on electronic ignition does not, until the power is back. New units also have to meet the federal efficiency minimum, which is set by a formula tied to the tank's rated volume rather than one number for every size, so two tanks of the same type can carry different minimums depending on how much they hold.

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 that isn't hot anymore, or runs out fast. Rust colored water from the hot tap, a tank that's rusting on the outside, or puddles forming around the base mean the tank itself is failing, not just a part inside it. Popping or rumbling sounds point to sediment built up on the bottom, which gets worse over time and makes the unit work harder to heat the same amount of water. If your tank is old and giving you any of these signs, it's worth having a contractor look at it before it fails outright and leaves you without hot water or with a leak to clean up.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on any rule that says everyone should switch. A tankless unit heats water only when you open a hot tap, so it doesn't keep a tank of water hot around the clock, and it won't run out partway through a long shower the way a tank can. It also takes up much less space and can last longer than a tank unit with the right upkeep. Against that, it costs more upfront and needs a contractor to check that your gas line, venting, and electrical can support it, since not every home is set up for one without changes.
- What changes when you install a tankless water heater?
- The biggest change is that hot water becomes available as long as you need it, since there's no tank to run dry. You'll also get a smaller unit, usually mounted on a wall, in place of the tank taking up floor space. On the practical side, a tankless unit often needs a larger gas line or a dedicated electrical circuit, and different venting than your old tank used, so a contractor has to check what your home already has before installing one. Some homes need those upgrades done as part of the switch, which is something only a contractor can price after seeing the setup.
