What Lancaster County winters ask of a water heater
Groundwater coming into the tank is already cold when December through February nights average 24°F, so the unit works harder to bring it up to temperature. That heating season runs seven months here, October through April, which means a new water heater is rarely idle.
Power is part of the picture too. In 2024, 15% of Pennsylvania households went at least 24 hours without power, and this county has seen 16 winter storms and 215 damaging wind events over the past ten years. Any new installation should account for what happens to hot water when the power drops, and for how long. Whatever size and type you choose, the federal minimum efficiency it has to meet is set by a formula tied to its rated volume, so a larger tank and a smaller one are held to different numbers even within the same type of heater.

A heat pump water heater would save about $390 a year to run in Pennsylvania compared with an electric water heater.

- How do I know it's time to replace my water heater?
- The clearest sign is water around the base of the tank, because a storage tank that has started to leak from the tank itself will not stop. Rust colored water from the hot side, a pilot or igniter that won't stay lit, or hot water that runs out much faster than it used to are also signs the tank is failing rather than just needing a repair. If your water heater is old and any of these show up, replacing it before it fails is easier than dealing with a flooded closet or basement. A contractor can tell you whether what you're seeing is a tank problem or something smaller, like a heating element or a thermostat.
- Should I switch to a tankless water heater?
- It depends on what you want out of your hot water and what your home can support, not just on whether tankless is newer technology. A tankless unit heats water only as you use it, so you don't run out during a long shower or back to back loads of laundry the way you can with a storage tank. But it usually needs different gas or electrical service than a tank did, so the switch is more involved than a straight swap. A contractor can look at your gas line, venting, and electrical panel and tell you what installing tankless would actually require in your house.
- What changes when you install a tankless water heater?
- The unit itself changes size and location, since a tankless heater mounts on a wall instead of standing on the floor, and it often goes in a different spot to reach venting or a gas line. Many tankless units need a larger gas line than a tank did, because they heat water on demand and draw more gas at once. Venting changes too, since tankless units typically vent through PVC rather than the metal flue a tank used. A contractor will check your gas supply, venting path, and electrical outlet before installation, since those often need work along with putting in the new unit.
