What a water heater in Aquia Harbour is up against
Winter nights here average 28°F from December through February, and the incoming water is coldest right when the tank works hardest. A new water heater has to recover through that cold stretch every year it's in service.
Power is the other risk. Across Virginia, 22 percent of households lost power for at least 24 hours in 2024, and this area has logged 8 winter storms and 132 damaging wind events over the past ten years. A gas water heater with a standing pilot will keep making hot water through an outage. One that depends on electric ignition won't, until the power is back.
Whatever model goes in has to clear the federal minimum efficiency for its size and type. That minimum is set by a formula tied to the tank's rated volume, not one number for every water heater, so the actual minimum depends on the size you install.

- How do I know it's time to replace my water heater?
- Look at the age first. Most tank water heaters have a working life span, and once yours is old enough that a repair costs nearly as much as replacing it, a contractor will usually tell you to replace it. Rusty water from the hot tap, a tank that's damp or rusted at the base, or water that never gets as hot as it used to all point the same way. If a contractor tells you the tank itself is leaking, that's the end of the line. Tanks aren't patched, they're replaced.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on your old tank failing. A tankless unit heats water as you use it instead of storing it, so you don't run out during back to back showers the way you can with a tank. It also takes up less space and tends to last longer than a storage tank. Against that, installing one can mean changes to the gas line, venting, or electrical that a storage tank replacement wouldn't need, and a contractor has to look at your home to know which apply. Winters here run cold, averaging 28°F December through February, and colder incoming water makes a tankless unit work harder to hit the same temperature, so it's worth asking a contractor to walk through how that affects sizing for your house.
- What changes when you install a tankless water heater?
- The unit itself is smaller and usually goes on a wall instead of taking up floor space. Because it has no tank, it needs enough gas or electrical capacity to heat water on demand, and that often means upgrading the gas line, the electrical circuit, or the venting to match what the new unit requires. Where it's installed and how it's vented can also change from where the old tank sat. A contractor will look at your home's gas, electrical and venting setup before quoting the job, since what needs upgrading varies house to house.
