Cold nights and long winters shape what a new tank needs to do
Delta County homes need heat from September through May, nine months of the year. A water heater here spends most of the year working against cold groundwater, and on winter nights that average 17°F from December through February, incoming water is at its coldest right when demand for hot water is steady. That is a long stretch for a tank to hold up under.
Weather here also cuts power. The county has logged 192 winter storms and 42 damaging wind events over the past ten years, and across Colorado, 13% of households lost power for 24 hours or more in 2024. A gas water heater with a standing pilot stays lit through an outage and needs no power to run. One with electronic ignition will not fire until power is back. That difference is worth weighing when choosing a new unit, not just matching whatever was there before.

A heat pump water heater would save about $370 a year to run in Colorado compared with an electric water heater.

- How do I know it's time to replace my water heater?
- Start with what the tank is telling you, not just its age. Rust-colored water, a tank that's rusting on the outside, water pooling underneath, or water that's no longer getting hot are signs the tank itself has failed rather than a single part. A leaking tank won't stop leaking on its own. That one calls for replacement, not a repair.
- Should I switch to a tankless water heater?
- It depends on what you want from it, not on whether tankless is better in general. A tankless unit heats water on demand instead of storing it, so you don't run out partway through back to back showers, while a storage tank holds a set amount and keeps reheating it whether anyone's using it or not. Switching also means changes to the gas line, venting, and sometimes the electrical, since a tankless unit has different requirements than the tank it replaces. A contractor can look at your home and tell you what that involves for your setup.
- 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, but what changes around it matters more. Tankless units often need a larger gas line to deliver enough fuel for the burner to heat water instantly, and they vent differently than a tank, usually through a dedicated vent sized for that unit. Some installations also call for an electrical outlet nearby for the unit's controls. A contractor evaluating your home can tell you which of these apply to your gas line, venting, and electrical.
