What Evanston winters ask of a water heater
Winter nights here average 10°F from December through February, and the ground water feeding your tank comes in cold. A water heater has to work harder to bring that water up to temperature, and it does that work most of the year, since homes here need heat from September through June.
Power loss is worth planning for too. Wyoming saw 8% of households go at least 24 hours without power in 2024, and Uinta County has logged 10 winter storms and 50 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 will not light until the power is back.
When you replace a tank, the new one has to meet the federal minimum efficiency for its type. That minimum is not one number. It is set by a formula based on the tank's rated volume, and it works out differently depending on the size you choose.

A heat pump water heater would save about $300 a year to run in Wyoming compared with an electric water heater.

- How do I know it's time to replace my water heater?
- The clearest sign is water that comes out rusty or that never quite gets hot anymore. A tank that's leaking from the bottom, or one making rumbling or popping sounds, is failing from sediment buildup inside and won't be fixed by a repair. Most tank water heaters have a working life measured in years, not decades, so if yours is old and starting to act up, replacing it before it fails outright saves you from a flooded utility closet. A cold night here in Evanston is a bad time to find out your heater quit overnight, so if it's showing any of these signs, get it looked at before winter sets in rather than after.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on your house needing one. A tankless unit heats water only when you turn on a tap, so you don't pay to keep a tank of water hot all day, and it won't run out partway through back-to-back showers the way a tank can. The tradeoff is upfront cost and the fact that a tankless unit needs the right gas line or electrical circuit to run, which your existing setup may or may not already have. A contractor can tell you whether your home is set up for one or what it would take to get there.
- What changes when you install a tankless water heater?
- The biggest change is that a tank disappears entirely, replaced by a unit about the size of a suitcase mounted on the wall. Because it heats water on demand instead of storing it, it needs a gas line sized to handle a much higher burner output, or in an electric model, a dedicated circuit that can carry a heavy load. Venting changes too, since a tankless unit typically vents through a wall with its own dedicated pipe rather than tying into an existing flue. All of this means the installation itself is more involved than swapping one tank for another, so a contractor will need to check your gas line, electrical panel and venting before giving you a plan for the job.
