What Portsmouth asks of a new water heater
Winter nights here average 35°F from December through February, and homes need heat from November through April, six months of the year. A water heater has to draw and warm colder groundwater through that whole stretch, and one sitting in a garage or unconditioned space works against cold air on top of that.
Power is the other thing to plan for. Statewide, 22% of Virginia households went at least 24 hours without power in 2024, and this area has logged 6 winter storms and 22 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps making hot water through an outage. One with electronic ignition or an electric element does not. Whatever gets installed also has to meet the federal minimum efficiency for its size, a number set separately for each tank volume and draw pattern rather than one figure for every heater.

- How do I know it's time to replace my water heater?
- If your water heater is old and starting to act up, that combination is your best signal. Watch for water pooling at the base, since that usually means the tank itself is rusting through from the inside, and a repair will not fix that. Rusty or metallic-smelling hot water, a tank that is noisy, or hot water running out faster than it used to are also signs the tank is near the end. Replacing it before it fails outright means you get to choose the timing instead of dealing with a flood or a cold shower.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on where you live. A tankless unit heats water on demand instead of storing it, so you get a steady supply of hot water without a tank slowly reheating in the background. That can matter if your household regularly runs the tank dry, or if you want to free up the closet or utility space a tank takes up. It needs the right gas line or electrical capacity to work, so a contractor should look at your home before you decide either way.
- What changes when you install a tankless water heater?
- The biggest change is that hot water gets made as you use it instead of sitting ready in a tank. That means no more running out of hot water partway through a shower, but the unit needs enough gas supply or electrical capacity to heat water fast, which sometimes means upgrading a gas line or a circuit. Tankless units mount on a wall and take up a fraction of the space a tank does, so where it goes in the house usually changes too. Venting is different as well, since tankless units need their own vent sized for the unit rather than sharing the setup a tank used.
