What a Cortez winter asks of a water heater
Water heaters here work eight months a year, October through May, with winter nights averaging 19°F. Cold incoming water takes more energy to heat, and a tank running that long needs to be sized right from the start.
Montezuma County has seen 115 winter storms and 22 damaging wind events over the past ten years. Across Colorado, 13% of households lost power for at least 24 hours in 2024. A gas water heater with a standing pilot keeps working through an outage. An electric one waits for the power to come back. Whatever fuel you choose, the unit has to meet a federal minimum efficiency, and that minimum is set by the tank's size. The right size for your home is not automatically the right size for the house next door.

- How do I know it's time to replace my water heater?
- Water pooling around the base or rust in the water are the two signs that mean stop waiting. Once a tank leaks at the tank itself rather than a fitting, it will not get better and will only get worse. A water heater working harder than it used to, taking longer to recover after a shower, or making a rumbling sound from sediment built up on the bottom is also nearing the end. If yours is old and giving you any of these signs, get it looked at before it fails outright and floods the area around it.
- Should I switch to a tankless water heater?
- It depends on what you want from it, not on your home being any different from another. A tankless unit heats water only as you use it, so you get endless hot water instead of running out partway through a shower, and it takes up far less space than a tank. It costs more to install and needs gas line and venting changes a tank never did. A contractor can look at your gas supply, your venting, and how much hot water your household actually uses, then tell you whether the switch makes sense for your house.
- What changes when you install a tankless water heater?
- The biggest change is that hot water no longer runs out. A tank holds a fixed amount and once it is gone you wait for it to reheat. A tankless unit heats water on demand, so as long as it is sized right for your fixtures, it keeps up no matter how long the shower runs. Installing one also usually means new venting, since tankless units vent differently than tank models, and in some cases a larger gas line to supply the burner. Some households also see their gas or electric use drop because the unit is not keeping a full tank hot around the clock, though how much depends on the household.
