What winter in Wood County asks of a water heater
Nights here average 10°F from December through February, and the heating season runs nine months, September through May. That is most of the year with cold water coming into the house and a water heater making up the difference.
Power is part of the picture too. Wisconsin saw 18% of households lose power for 24 hours or more in 2024, and Wood County has logged 25 winter storms and 47 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps making hot water through an outage. One with electronic ignition will not light until the power is back. Whatever you install, it has to meet the federal minimum efficiency for its size and draw pattern, and that number is different for every tank size, so the right one depends on which you choose.

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?
- Water pooling around the base, water that comes out rusty from the hot side only, and a tank making popping or rumbling sounds are the clearest signs. That popping is sediment that has settled and hardened on the bottom, and once that builds up the tank works harder and can crack. Age matters too, so if yours is old and starting to act up, replacing it before it fails is worth doing. A unit that fails outright usually does it without warning, and with winter nights here dropping to 10°F, going without hot water while a replacement gets scheduled is worse than planning ahead.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on any problem with your current tank. A tankless unit heats water on demand instead of storing it, so you get a steady supply as long as it's running and never run out mid-shower. It also takes up much less space than a tank. What it won't do is deliver hot water instantly at the tap, since the water still has to travel through the pipe from the unit to you. A contractor can look at your gas line, venting, and water usage to say whether tankless makes sense for your house specifically.
- What changes when you install a tankless water heater?
- The biggest change is that a tankless unit needs a gas line and venting sized for it, and both are often different from what a storage tank used. Tankless units draw more gas at once to heat water quickly, so the existing gas line may need to be upsized. Venting changes too, since tankless heaters vent differently than most tank models. None of this is guesswork a homeowner should do alone. A licensed contractor, registered with Wisconsin's Department of Safety and Professional Services, will check the gas supply, venting, and water lines before installing to make sure everything is sized correctly for the new unit.
