What a new water heater needs to handle in Dundalk
Incoming water runs cold here. Winter nights average 26°F from December through February, and a water heater has to work harder to bring that water up to temperature during those months, on top of a house that's already asking for heat seven months a year, October through April.
Power is worth planning for too. Statewide, 11% of Maryland households went at least 24 hours without power in 2024. A gas unit with a standing pilot will keep making hot water through an outage that would shut an electric one down. On the efficiency side, the federal minimum for a storage water heater isn't one number. It's a formula based on the tank's rated volume, applied separately across four draw patterns, so the minimum your new unit has to meet depends on its size and how much hot water your household uses.

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?
- Look at what the water heater is telling you, not just how old it is. Rust colored hot water, a tank that's sweating or rusting on the outside, or water pooling underneath are signs the tank itself is failing, and that's not something a contractor can patch. If it's still making hot water but taking longer to recover between showers, or making a rumbling sound while it heats, that's usually sediment built up inside the tank and worth having looked at before it gets worse. A contractor can tell you whether what you're seeing means repair or replacement.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on whether your current tank is failing. A tankless unit heats water on demand instead of storing and reheating it, so you don't run out mid-shower, and it takes up less space since there's no tank to house. Just over half of homes in Baltimore County heat with gas, and tankless units run on either gas or electric depending on the model and what your home already has. Switching usually means changes to the gas line, venting, or electrical circuit, so a contractor needs to see your setup before you know what that means for your house.
- What changes when you install a tankless water heater?
- The unit mounts on a wall instead of standing on the floor, which frees up the space the old tank used. Venting is different too. A tankless unit needs its own vent sized for it rather than sharing a flue the way some tank water heaters do. The gas line or electrical circuit feeding it may need to be upsized, since it draws a burst of energy to heat water instantly instead of drawing steadily to keep a tank warm. Because this changes the venting and the gas or electrical connection, it needs a permit from the local building office and an inspection once the work is done.
