A new water heater here works eight months of cold into every year
Winter nights in Allegheny County average 24°F from December through February, and homes need heat from October through May. That's eight months where the water coming into the tank is already cold, and the heater has to work harder to bring it up to temperature. A tank sized and rated for that draw matters more here than it would somewhere warmer.
Power is worth planning around too. Across Pennsylvania, 15% of households lost power for 24 hours or more in 2024, and the county has logged 12 winter storms and 548 damaging wind events over the past ten years. If you're choosing between a gas and an electric water heater, that history is worth weighing. Whatever you install, the federal minimum efficiency it has to meet is set by a formula based on the tank's size, not one flat number, so the minimum for your new heater depends on how many gallons it holds.

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?
- If it's leaking from the tank itself, that's the clearest sign, and there's no fixing it. Water pooling underneath means the tank has rusted through from the inside, and once that starts it only gets worse. Age matters too. Most tank water heaters last 8 to 12 years, so if yours is in that range and giving you trouble, cold water, rumbling, water that looks rusty, it's worth having someone look at it rather than waiting for it to fail outright. A tank that fails while you're away can mean a basement full of water, so don't ignore the warning signs.
- 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 it flows through rather than storing and reheating a tankful, so you don't run out of hot water partway through a shower and it doesn't sit there losing heat when nobody's using it. What it won't do is fix a house with old or undersized gas piping or electrical service on its own, since tankless units often need more of both than a tank did. A contractor can tell you what your house would need to make the switch work.
- What changes when you install a tankless water heater?
- The unit itself is smaller and mounts on a wall instead of taking up floor space, so you get that room back. Behind the wall, though, a few things usually have to change. Gas units often need a larger gas line to deliver enough fuel for the burner to heat water on demand, and they need venting sized and routed for that unit specifically, not whatever venting the old tank used. Electric tankless units draw a lot of power, enough that many homes need an electrical panel upgrade to handle it. None of this is a reason to avoid it, it's just what has to be planned for before the old tank comes out.
