What a water heater in La Plata has to handle
Winter nights here average 29°F from December through February, and a water heater has to bring in water that's just as cold and get it up to temperature every time someone runs a tap. That's the season it works hardest, and it runs that way for months.
Charles County has recorded 11 winter storms and 188 damaging wind events over the past ten years, and across Maryland, 11% of households lost power for 24 hours or more in 2024. A gas water heater with a standing pilot keeps making hot water through an outage. One that relies on an electric igniter does not.
New storage water heaters also have to meet a federal minimum efficiency, and it isn't one number. It's a formula tied to the tank's rated volume, applied separately across four draw patterns, so two tanks of the same type but different sizes can face different minimums.

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?
- Water pooling at the base of the tank means it's leaking, and that's not something to wait on. Rusty or metallic-tasting hot water is another sign, especially if it doesn't clear up after running the tap a while. If the water isn't getting as hot as it used to, or you hear rumbling or popping from the tank, sediment has likely built up on the bottom and the unit is working harder than it should. Age matters too, so if you're not sure how old the tank is, that's worth finding out even if nothing looks obviously wrong yet.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on any rule that says tankless is better. A tankless unit heats water only as you use it, so you don't pay to keep a tank full of hot water sitting around all day. It also takes up less space and tends to last longer than a storage tank. Against that, a tankless unit costs more to install and may need upgraded gas or electric service to run, so whether it makes sense for your house is a question a contractor can answer once they've looked at what you have.
- What changes when you install a tankless water heater?
- The biggest change is what's on the wall instead of in the closet or basement. A tankless unit mounts on the wall and takes a fraction of the floor space a tank does. It also needs its own venting, sized and run differently than a tank's venting, and depending on the model, may need larger gas piping or a dedicated electric circuit to deliver enough power to heat water on demand. Because this touches gas or electric lines and venting, the job needs a permit and inspection through the local building office, the same as installing a storage tank does.
