Cold groundwater and long winters wear on your water heater here
Winter nights in Deer Lodge County average 13°F from December through February, and the water coming into your tank starts that cold. The tank has to work harder and longer to bring it up to temperature, and it does this every day, all year, since homes here need heat in some form 12 months a year. That steady demand wears on the heating element and the thermostat that controls it.
Power is part of it too. Across Montana, 18% of households lost power for 24 hours or more in 2024, and this county has seen 49 winter storms and 15 damaging wind events over the past ten years. When power drops in the middle of a heating cycle and comes back on, most tanks recover on their own, but the repeated strain adds up over the years. If your water is taking longer to heat, running out faster than it used to, or the tank is making noise it didn't before, that is the wear showing itself.

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 leaking, which means it needs to be replaced, not repaired. Before assuming that, check the drain valve at the bottom and the fittings above it, since a loose valve or a leaking pipe connection can look like a tank leak but is a simple fix. Water pooling underneath can also come from condensation or from the temperature and pressure relief valve venting, so a contractor needs to trace where the water is actually starting from before deciding what it means for your tank.
- Why won't the pilot light on my water heater stay lit?
- A pilot that won't stay lit is usually the thermocouple, the small sensor that tells the gas valve the flame is burning. When it wears out or sits out of position, the valve shuts the gas off as a safety measure even though the pilot lit fine a moment before. A weak gas supply or a draft in the flue can cause the same thing, so a contractor will check the thermocouple first and then look at gas pressure and venting if that doesn't solve it. A standing pilot runs on gas alone, so it stays lit through a power outage, which matters here given how often winter storms knock the power out.
- Can a tankless water heater be repaired?
- Yes, most tankless problems are repairable. Mineral buildup on the heat exchanger is the most common issue, and it's cleared with a descaling flush rather than a replacement. Ignition failures, sensor faults and error codes usually point to one part, like the igniter or a flow sensor, that a contractor can test and swap out. Replacement only comes up when the heat exchanger itself has failed or cracked.
