What Cumberland winters ask of a water heater
Winter nights here average 24°F from December through February, and homes need heat running eight months of the year, October through May. A water heater works alongside the furnace through that whole stretch, not just the coldest weeks.
Power is part of the picture too. Maryland households went without power for 24 hours or more at an 11% rate in 2024, and this county has logged 56 winter storms and 106 damaging wind events over the last ten years. A gas water heater with a standing pilot keeps working through an outage. One that depends on an igniter does not, until the power is back. Whatever you install, it also has to clear the federal minimum efficiency for its size and type, which is set separately for each tank volume rather than as one number for every heater.

A heat pump water heater would save about $420 a year to run in Maryland compared with an electric water heater.

- How do I know it's time to replace my water heater?
- The clearest sign is rusty water coming from the hot tap, since that usually means the tank itself is corroding from the inside. Water pooling around the base, a tank that's making popping or rumbling sounds, or hot water running out faster than it used to are other signs the tank is on its way out. A unit that's leaking from the tank itself, rather than a fitting or valve, can't be repaired and needs replacing. If yours is old and starting to act up, it's worth having a contractor look at it before it fails and leaks.
- Should I switch to a tankless water heater?
- It depends on what you want out of it. A tankless unit heats water on demand instead of storing it, 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 around the clock. It also takes up much less space than a storage tank. Against that, a tankless unit needs a gas line or electrical circuit sized for its higher draw, and venting rules for it are different from a standard tank. A contractor can look at your gas line, electrical panel and where the unit would go and tell you whether your house is a straightforward switch or needs extra work first.
- What changes when you install a tankless water heater?
- The biggest change is what feeds it. A tankless unit pulls a lot more gas or electricity for the short time it's running than a storage tank does, so the gas line or circuit often needs to be upsized to match. Venting changes too, since tankless units use their own vent type rather than the flue a storage tank uses. The unit itself mounts on a wall rather than sitting on the floor, which frees up space but means the water and gas lines have to be run to wherever it's mounted. Because the gas line, electrical, and venting can all be affected, a contractor needs to check what's already in place before pricing the switch.
