What a Westminster winter asks of your water heater
Winter nights here average 25°F from December through February, and the incoming water is that cold too. A new water heater has to bring that water up to temperature every time someone runs a shower or starts the dishwasher, and the colder the supply, the harder it works to get there.
Carroll County has seen 21 winter storms and 173 damaging wind events over the past ten years, and in 2024, 11% of Maryland households lost power for 24 hours or more at some point. Most gas water heaters with a standing pilot keep working through a power outage, since they don't need electricity to run. If you're choosing between fuel types or between tank and tankless, that's worth weighing alongside everything else. Whatever you install, it has to meet the federal minimum efficiency for its size, which is set separately for each tank volume rather than as one number for every water heater.

- How do I know it's time to replace my water heater?
- The clearest sign is water that doesn't get hot anymore, or runs out faster than it used to. Rust colored water, a tank that's rusting on the outside, or water pooling underneath it are all signs the tank itself is failing, and a leaking tank needs to be replaced, not repaired. A popping or rumbling sound when it heats up means sediment has built up on the bottom, which makes the tank work harder and wears it out sooner. Most storage tanks last a decade or a bit more, so if yours is getting up there in age and starting to act up, replacing it before it fails is worth doing on your own schedule instead of waiting for a flood.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on which one is better in every home. A tankless unit heats water as it flows through, so you don't run out of hot water partway through a shower, and it doesn't sit there keeping a tank of water hot all day when nobody's using it. Switching means changing how the unit connects to your gas line, your vent, and sometimes your electrical panel, since a tankless unit has different requirements than a tank. A contractor can look at your current setup and tell you what changes and what that means for your house.
- What changes when you install a tankless water heater?
- The unit itself is much smaller and mounts on a wall instead of standing on the floor, so it changes where and how it fits into the space. It needs its own venting, run to the outside, which is different from what a tank uses. Gas fired models often need a larger gas line than the one feeding the old tank, because they draw more gas for the moment water is running through them. Any of this work needs a permit and an inspection when it's done, and a contractor can walk through what your house needs before the swap.
