What Chester winters ask of a water heater
Your water heater works into cold ground water for seven months a year here, October through April, with winter nights averaging 27°F. The colder the water coming in, the harder the unit works to bring it up to temperature, and that load falls on a tank every day of those seven months.
Delaware County sees its share of winter storms and damaging wind, and 15% of Pennsylvania households lost power for at least 24 hours in 2024. A storage tank with a standing pilot will keep making hot water through an outage. One with electronic ignition will not light until power is back, though it comes back on by itself once it is. Either way, sizing and setup matter more here than in a milder climate, and the federal minimum efficiency your new unit has to meet is set by its rated volume, so the right minimum depends on the size tank your household needs.

A heat pump water heater would save about $400 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 age, along with what shape the tank is in. Water pooling at the base means the tank has rusted through from the inside, and that's a replacement, not a repair. Rusty hot water, a tank that's making noise, or a pilot that won't stay lit are worth having a contractor look at too. Winter nights here average 27°F, and homes need heat October through April, so a water heater that's already showing its age is worth replacing on your schedule rather than waiting for it to fail in the cold.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not just on your current tank failing. A tankless unit heats water on demand, so you don't run out during back to back showers the way you can with a tank. They also tend to last longer than storage water heaters. The tradeoff is that installation is more involved than a tank swap, since venting and gas or electric supply requirements are different. A contractor can look at your home and tell you whether the switch makes sense for your setup.
- What changes when you install a tankless water heater?
- The biggest change is that you stop storing hot water and start heating it as you use it. That means no more running out partway through a long shower, but the unit has to be sized correctly for your fixtures or you'll notice the difference at the tap. Venting is different too. Tankless units often need different venting than a tank did, which can mean new venting through a wall or roof. Because the requirements differ from a standard tank, this is a job for a contractor who can check your home's gas line, electrical, and venting before quoting the work.
