What a Nixa water heater has to handle
Winter nights here average 26°F from December through February, and most homes run their heat from October through April. Cold groundwater means your water heater works harder to bring water up to temperature, and it does that job seven months of the year.
Power is part of the picture too. Missouri saw 19% of households lose power for 24 hours or more in 2024, and Christian County has logged 11 winter storms and 143 damaging wind events over the past ten years. A gas water heater with a standing pilot will keep working through an outage. One with electronic ignition will not light until power is back. Whatever you install, it has to meet the federal minimum efficiency rule for its size, which is set separately for each tank volume rather than as one number for every unit.

- How do I know it's time to replace my water heater?
- Check the age on the tank's label first, most storage water heaters wear out over time rather than failing all at once. Rust-colored water, a tank that's damp or sweating at the base, or water that won't get as hot as it used to are signs the tank itself is failing, not just a part inside it. A leak at the tank means replacement, since the tank can't be patched. If you're only losing hot water partway through a shower and the tank looks dry, that's more likely the thermostat or heating element, and worth having a contractor check before you assume you need a new one.
- Should I switch to a tankless water heater?
- It depends on what problem you're trying to solve. Tankless units heat water as it flows instead of storing it, so they don't run out the way a tank can. If your household regularly runs hot water dry, back to back showers or a shower running while the dishwasher's going, a tankless unit fixes that. If running out has never been an issue, a standard tank heater does the same job with a simpler installation. A tankless unit also needs a gas line and venting sized for it, so a contractor should confirm your home can support that before you decide.
- What changes when you install a tankless water heater?
- The gas line usually needs to be larger, since a tankless unit draws more gas to heat water on demand instead of keeping a tank warm. Venting changes too. Tankless units vent differently than a standard tank, and that often means running new venting to the outside. There's no tank standing by, so you also lose that reserve of already-hot water sitting ready. A contractor will need to check the gas supply and venting path in the specific house before installation, since those two things decide whether the swap is straightforward or more involved.
