What a St. Paul winter asks of your water heater
Groundwater coming into your house is already cold before your heater does anything to it, and in a Ramsey County winter it starts colder still. Your water heater works to make up that difference every day for eight months a year, October through May. A unit sized and installed right for that load will hold up. One that's undersized or already worn down will run harder to keep up, and that catches up with it.
Power doesn't always stay on through a bad storm. Minnesota households saw outages of a day or longer in 2024, and Ramsey County has logged dozens of winter storms and damaging wind events over the past ten years. Gas water heaters with a standing pilot keep working through an outage. Most electric units and gas units with electronic ignition come back on by themselves once power returns, but they sit cold until then. New storage water heaters also have to meet a federal minimum efficiency standard, and that minimum is set by the tank's size and how the household draws hot water, so the right benchmark for your install depends on the unit you're replacing it with.

A heat pump water heater would save about $360 a year to run in Minnesota compared with an electric water heater.

- How do I know it's time to replace my water heater?
- Water pooling around the base is the clearest sign, and it usually means the tank itself has failed inside. Rusty water, a pilot that won't stay lit, or water that never gets as hot as it used to are the other signs worth acting on. Tank water heaters don't get better on their own once they start failing, they tend to get worse from there. If yours is giving you any of these signs, it's worth having someone look at it rather than waiting for the leak.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not just on your old tank failing. A tankless unit heats water as you use it, so you don't run out during a long shower or back to back loads of laundry, and it doesn't sit there keeping a tank of water hot all day. What it won't do is fix low water pressure or an undersized gas line, those are separate issues a contractor checks before recommending one. Most homes in this county heat with gas already, which makes a gas tankless unit a more straightforward swap. Switching from electric is a bigger change.
- What changes when you install a tankless water heater?
- The biggest change is venting. A tankless unit vents differently than a tank, often through the wall rather than up through the roof, so the spot it goes in may need new venting run to it. Gas units also need to be sized to your home's demand, meaning the gas line itself sometimes has to be upsized to feed it. None of this means something is wrong with your house, it's just part of the job a contractor plans for before the install starts, and it's why putting in a tankless unit usually takes more work than swapping one tank for another.
