What a Camden County winter asks of your water heater
Winter nights here average 25°F from December through February, and the water coming into your house is that cold too. Your water heater has to bring it up to temperature seven months a year, October through April.
Power is part of the picture. A large share of Missouri households went at least 24 hours without power in 2024, and this county has seen 7 winter storms and 57 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps working through an outage. One with electronic ignition, or an electric tank, will not heat water until power is back. Whatever you install also has to meet a federal minimum efficiency, and that minimum is set by the tank's size, so the number that applies depends on the unit you choose.

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?
- The clearest sign is water pooling around the base of the tank. Once a tank starts leaking, it will not stop, since the steel has rusted through from the inside. Rusty or metallic-tasting hot water and a tank making rumbling or popping sounds are also signs it is failing, usually from sediment that has built up on the bottom over years of use. If your water heater is showing any of these, a contractor can tell you whether it is worth repairing or time to replace it.
- Should I switch to a tankless water heater?
- It depends on what you want from your hot water and what your home can support. A tankless unit heats water only as you use it, so you get a steady supply without a tank running out partway through back to back showers. But installing one often means changes to the gas line, venting, or electrical circuit that a storage tank never needed, since tankless units draw more power at the moment they fire up. A contractor can look at your home's setup and tell you what switching would actually involve.
- What changes when you install a tankless water heater?
- The biggest change is what feeds the unit. Gas tankless water heaters usually need a larger gas line than a storage tank used, because they burn much more fuel in the moment to heat water on demand. Venting changes too, since tankless units require their own vent type and routing rather than sharing what the old tank used. Electric models need enough amperage on the circuit to handle the load. A contractor can check your gas line, venting, and electrical panel to see what your home would need.
