What San Bernardino County asks of a water heater
Winter nights here average 39°F from December through February, and homes across the county run their heat five months a year, November through March. That is not extreme cold, but it means the water coming into your heater is colder for a real stretch of the year, not just a few weeks.
Power is the bigger question. Across California, 17% of households lost power for 24 hours or more in 2024, and this county has logged 89 winter storms and 425 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps working through an outage. One with electric ignition does not, and an electric tank heater will not either. Worth knowing before you pick a replacement. Whatever you install, it has to meet the federal minimum efficiency for its size, which is set separately by tank volume rather than as one number across the board.

A heat pump water heater would save about $780 a year to run in California compared with an electric water heater.

- How do I know it's time to replace my water heater?
- Age is the first thing to check. Once a tank water heater gets old, the tank itself becomes more likely to fail than any part inside it. Rust colored water from the hot tap, a tank that's rusting on the outside, or water pooling underneath are signs the tank is going, not something to patch. If it's making popping or rumbling sounds, that's sediment built up on the bottom, and it means the heater is working harder than it should. A unit that's still fairly young and just needs a part is usually worth repairing instead.
- 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 instead of storing it, so you don't run out of hot water partway through back to back showers or a full load of laundry. It also doesn't sit there keeping a tank of water hot all day when nobody's using it. Switching means a different kind of install than swapping one tank for another, so a contractor will need to look at your gas line, venting, and where it can go before pricing it out.
- What changes when you install a tankless water heater?
- The unit itself is smaller and mounts on a wall instead of standing on the floor, so it frees up the space the old tank used. It needs its own venting, and depending on the model, that venting runs differently than a tank heater's did, so the path through the wall or roof usually has to be redone rather than reused. Tankless units also demand more gas flow in the moment, since they're heating water on demand instead of drawing from a stored supply, which means the gas line has to be checked to see if it can keep up. A contractor will need to look at the house to say what needs to change to make the switch.
