What a Pottsville winter asks of a water heater
Water heaters here work through eight months of heating season, October through May, with winter nights averaging 21°F. That is a long stretch of cold months for a tank to keep up with.
Schuylkill County has logged 20 winter storms and 71 damaging wind events over the past ten years, and across Pennsylvania 15% of households lost power for 24 hours or more in 2024. A gas water heater with a standing pilot keeps working through an outage like that. One that needs power to ignite does not, until the power comes back. Whatever you install, the federal minimum efficiency it has to meet depends on your tank's rated volume, so the number that applies to your size tank is not the same one that applies to a bigger or smaller one.

- How do I know it's time to replace my water heater?
- Look at the age first. Most tanks last about 10 years, and once you're past that, a repair is just a patch on something close to failing anyway. Water pooling at the base is usually the tank itself rusting through from the inside, and that doesn't get fixed, only replaced. Other signs to watch for are water that comes out rusty or metallic-tasting, a tank that makes rumbling or popping sounds as sediment builds up on the bottom, or hot water that runs out faster than it used to. If your water heater sits in a spot where a leak would reach flooring or finished space below, don't wait once you see the first sign of tank corrosion.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on your old tank failing. Tankless units heat water on demand instead of storing it, so you don't run out of hot water partway through a shower or a load of laundry, and they don't sit there keeping a tank of water hot all day when nobody's using it. What they don't do is heat water faster in an emergency or work during a power outage, since the ones made for household use still need electricity to run even on a gas model. A contractor can look at your gas line, venting and household hot water use to tell you whether the switch makes sense for your house.
- What changes when you install a tankless water heater?
- The biggest change is that you stop storing hot water and start heating it as it flows through the unit. That usually means new venting, since tankless units vent differently than a tank, and it often means upsizing the gas line, because the burner has to heat water fast rather than slowly over time. The unit itself mounts on a wall instead of taking up floor space, which opens up the area where your old tank sat. A contractor needs to see your gas line, existing venting and where you want the unit placed before saying what the job actually involves in your house.
