What a Los Angeles water heater has to handle
Homes here need heat from November through April, six months a year, with winter nights averaging 41°F. A water heater is working through that same stretch, and a new one has to be sized and installed to keep up through it.
Power is part of the picture too. Across California, 17% of households lost power for 24 hours or more in 2024, and the county has recorded 112 damaging wind events and 9 winter storms over the past ten years. A gas water heater with a standing pilot keeps working through an outage. One with electronic ignition will not light again until power comes back. Whatever goes in has to meet the federal minimum efficiency set for its tank size, a number that changes with the volume rather than one figure for every heater.

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?
- The clearest sign is age combined with trouble. If your water heater is old and you're seeing rust-colored water, a tank that's noisy, or water that won't get hot anymore, it's closer to the end than the beginning. A leak at the tank itself, rather than a fitting or valve, means replace it now, since a tank does not get repaired once it's leaking. If a contractor tells you the tank is rusting from the inside, that's not something to patch.
- Should I switch to a tankless water heater?
- That depends on what you want out of it, not on any rule that says you should. A tankless unit heats water only when you're using it, so you don't run out partway through a shower and don't pay to keep a tank of water hot all day. It also takes different venting and gas or electric supply than a tank does, so switching is a bigger job than replacing a tank with another tank. A contractor can look at your gas line, venting, and where the unit would go and tell you what the switch actually involves in your house.
- 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. It needs its own venting, sized for that unit, and often a larger gas line than the one feeding a tank heater. Because it heats water on demand instead of storing it, hot water reaches every fixture as long as the unit is running, but very high simultaneous demand, like two showers and a dishwasher at once, can outpace what one unit produces. A contractor sizes the unit and the gas and venting to the house rather than swapping it in place of the tank.
