Cold water for seven months means longer recovery times
From October through April your incoming water runs cold. On nights that average 28°F it runs colder still. Your water heater has to work harder to bring it up to temperature, and it does this for seven months of the year. That extra runtime wears on the heating element or burner assembly faster than it would somewhere milder.
When the thermostat, heating element, or gas control valve starts to fail, you notice it in the shower first. Water turns lukewarm partway through, or never gets hot at all. A power outage can also shut a water heater down, and outages are not rare here. Most units come back on their own once power returns, but a unit that was already struggling may not recover the same way.

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 cracking under pressure. Once a tank starts leaking this way it will not seal or patch, since the failure is inside the steel where you can't reach it. It could also be a loose drain valve or a fitting weeping at the bottom, which a contractor can check before assuming the tank is done. If the leak is coming from the tank body, 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 sits in the pilot flame and tells the gas valve it is safe to stay open. When it wears out it can't hold that signal, so the valve shuts the gas off and the pilot goes out. A dirty or misaligned pilot orifice or a draft in the flue can cause the same thing. A contractor can test the thermocouple and replace it, which is a straightforward fix and doesn't mean the whole water heater is failing.
- 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 each one can be fixed without replacing the unit. Tankless units also run diagnostic error codes, so a contractor can often tell what's wrong before opening it up. Replacement is usually only needed when the heat exchanger itself has cracked or corroded through.
