Cold groundwater and long winters wear on a water heater here
Water heaters in Havre work against cold incoming water for ten months of the year, September through June. The colder the water coming in, the longer the burner or the heating element has to run to bring a tank up to temperature, and that extra run time wears on the thermostat and the heating element in an electric unit, or the burner assembly and thermocouple in a gas one.
Winter nights here average 8°F, and Hill County has seen 17 winter storms and 98 damaging wind events over the past ten years. Power loss is not rare in Montana, with 18% of households going at least a day without electricity in 2024. An electric water heater will not heat water until power is back, and a gas unit with an electronic ignition will not either, though one with a standing pilot keeps running through the outage. When the power comes back on, most units restart on their own, but if yours does not, that is worth checking.

A new water heater would cut about $60 a year off hot water for a typical Montana home.

Repair makes sense when an element, thermostat or gas valve has failed.
Replacement makes sense when the tank itself is leaking.
- Why is my water heater leaking from the bottom?
- Most often the tank itself has rusted through from the inside and is starting to fail. Sediment builds up at the bottom of the tank over years, and once it corrodes the steel, water finds its way out and there is no patching it. It can also be a loose drain valve or a fitting that has failed, which is a much simpler fix. A contractor can tell the difference by looking at where the water is actually coming from, but if it is the tank itself, the water heater needs to be replaced, not repaired.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small sensor that tells the gas valve the pilot is burning. When it wears out, it shuts the gas off even though the flame is lit. A dirty pilot orifice or a draft in the area can also blow the flame out. A contractor can test the thermocouple and clean or replace the parts causing it, and with winter nights here dropping to 8°F, a water heater that keeps going out is worth getting looked at before you are stuck without hot water in the cold.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Mineral buildup on the heat exchanger, a failed igniter, or a clogged inlet filter are common issues and none of them require replacing the whole unit. A contractor can flush the heat exchanger or replace the specific part that has failed. Tankless units run for many years when the parts inside are kept working, so repair is almost always the first option, not replacement.
