What a Salisbury winter asks of your water heater
Winter nights here average 29°F from December through February, and homes run their heat October through April, seven months a year. A cold house means cold incoming water, and your water heater has to make up more of a difference every time someone runs a shower or starts the dishwasher.
Power is part of the picture too. Wicomico County has logged 12 winter storms and 68 damaging wind events over the past ten years, and in 2024, 11% of Maryland households went at least 24 hours without power. A gas water heater with a standing pilot keeps working through an outage since it uses no electricity at all. One with electric ignition, and most electric water heaters, will sit idle until power comes back, then start up again on their own. Whatever you install has to meet the federal minimum efficiency for its size and type, a figure set separately for each tank volume rather than one number for every heater.

A heat pump water heater would save about $370 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 age. Tank water heaters have a limited lifespan, and once you're near the end of it, a repair is just delaying the next failure. Watch for water pooling around the base, rusty water from the hot tap, or a tank that makes rumbling sounds as sediment builds up on the bottom. If the unit is leaking from the tank itself rather than a fitting, that tank is done and needs replacing, not patching.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on whether one is better than the other everywhere. A tankless unit heats water on demand instead of storing it, so you don't run out during back to back showers, and it takes up a fraction of the space a tank does. It also costs more to install and may need changes to your gas line or electrical to run properly. A contractor can look at your home's setup and tell you what switching would actually involve.
- What changes when you install a tankless water heater?
- The biggest change is that hot water becomes available as long as you need it, since there's no tank to run dry. Venting is different too, tankless units often need a dedicated vent sized for the unit, not the flue a tank used. Gas units may need a larger gas line to deliver enough fuel for the burner to heat water instantly. Because this is a different type of installation, the local permit and inspection still apply, same as a standard water heater swap.
