What a Liberty winter asks of a new water heater
Winter nights here average 22°F from December through February, and cold groundwater coming into the tank means the burner or element works harder to bring it up to temperature. That is real load on a new unit from the day it goes in.
Power is part of the picture too. Statewide, 19% of Missouri households went at least a day without power in 2024. A gas water heater with a standing pilot keeps making hot water through an outage. One with electronic ignition will not light until the power is back. Whichever type goes in, it has to meet the federal minimum efficiency set for its tank size, which is figured separately for each size rather than as one flat number.

A heat pump water heater would save about $270 a year to run in Missouri compared with an electric water heater.

- How do I know it's time to replace my water heater?
- Look at the age first. Most tank water heaters have a working life measured in years, not decades, and once a tank is old, a repair is often just a delay before the next breakdown. Rust colored water, rust on the outside of the tank, or water pooling underneath are signs the tank itself is failing, and a tank that leaks can't be repaired. Rumbling or popping sounds mean sediment has built up on the bottom and the unit is working harder than it should. A contractor can tell you whether what you're seeing is worth fixing or whether the tank is done.
- Should I switch to a tankless water heater?
- It depends on what you want out of it. A tankless unit heats water on demand instead of storing it, so you don't run out partway through back to back showers, and it doesn't sit there keeping a tank of water hot when nobody's using it. It costs more to install than a like for like tank swap, and it may need changes to your gas line or venting to run properly. A contractor can look at your home and tell you what installing one would actually involve.
- What changes when you install a tankless water heater?
- The biggest change is that hot water gets made as you use it instead of pulled from a tank that's already heated. That means no standby heat loss, but it also means the unit needs enough gas supply and the right venting to fire at full output. Many homes need the gas line, vent, or electrical hookup upgraded to meet what the new unit requires, even when the old tank worked fine on what was there. A contractor can check your home's gas line, venting, and electrical setup before you decide.
