Eight months of hot water demand in Pueblo County
Winter nights here average 19°F from December through February, and homes need heat from October through May. A water heater in Pueblo County works through eight months of cold incoming water, which means the tank runs longer to bring it up to temperature.
The county has also seen 184 winter storms and 209 damaging wind events over the past ten years, and across Colorado 13% of households lost power for 24 hours or more in 2024. A new installation should account for what happens to the unit when the power goes out along with the cold. Federal efficiency minimums for storage water heaters are not one number. They are set by a formula tied to the tank's rated volume, so the minimum a new unit has to meet depends on its size.

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?
- The clearest sign is water that comes out rusty or metallic tasting from the hot side only. That means the tank itself is rusting from the inside. Water pooling at the base of the tank is another sign, since it usually means the tank has a crack or seam failure that will not seal itself. If the unit is making rumbling or popping sounds during heating, sediment has built up on the bottom of the tank, and that speeds up wear on the tank floor. A water heater that cannot keep up anymore, running out of hot water faster than it used to, is also telling you the tank or its heating element is failing, not that someone in the house is using more water.
- Should I switch to a tankless water heater?
- It depends on what you want out of your hot water and what your home can support, so a contractor needs to look at your gas line, venting, and water use before that question has a real answer. Tankless units heat water on demand instead of storing it, so you get continuous hot water rather than running out after a tank empties. They also take up much less space than a tank. Switching usually means changes to the gas line sizing and venting, since tankless units draw more gas at once than a standard tank, and that is the part a contractor prices for your specific house.
- What changes when you install a tankless water heater?
- The biggest change is how the unit is fed. Tankless heaters need a larger gas line than most storage tanks use, because they fire at a higher rate to heat water instantly rather than gradually. Venting changes too. Tankless units typically vent with a different pipe than a tank did, run to an outside wall rather than up through a chimney. Some homes also need an upgraded electrical connection for the unit's ignition and control system. None of this is guesswork, a contractor checks your existing gas line, vent path, and electrical setup before installation to know exactly what has to change in your house.
