Pueblo winters put steady demand on your water heater
Your water heater works harder from October through May, eight months of the year. Cold ground and cold intake water mean it has to run longer to hit the same temperature. On the nights that drop near 19 degrees, that strain lands on the parts that wear first. The heating element works overtime. The thermostat cycles more. The anode rod gets eaten down faster than it should.
Pueblo County has also seen its share of winter storms and wind events over the past ten years, and losing power is part of life here. Most water heaters come back on by themselves once power returns, but a unit already worn down may not recover the same way. If yours is making noise, running out of hot water sooner than it used to, or not heating like it did last year, that is worth a look before it fails outright.

A new water heater would cut about $60 a year off hot water for a typical Colorado home.

Repair makes sense when an element, thermostat or gas valve has failed.
Replacement makes sense when the tank itself is leaking.
- Why is my water heater leaking from the bottom?
- The most common cause is the tank itself failing from the inside, where sediment builds up over the years and corrodes the steel until it gives way. Once a tank leaks like this, it needs to be replaced, not repaired, because the damage is inside the lining. Water at the bottom can also come from a loose drain valve or a failed temperature and pressure relief valve, both of which a contractor can check before condemning the tank. If your water heater is old, an inspection will tell you which one you're dealing with.
- Why won't the pilot light on my water heater stay lit?
- Most of the time this means the thermocouple has worn out and can no longer hold the gas valve open once you let go of it. A dirty pilot orifice or a draft in the area can also blow the flame out. If the tank uses a standing pilot, it doesn't rely on household power, so a winter outage here won't be the cause. A contractor can test the thermocouple in a few minutes and replace it if it's reading weak.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Mineral buildup on the heat exchanger is the most common issue, and it's usually cleared with a descaling flush rather than a part replacement. Igniter failures, sensor faults, and error codes tied to venting or water flow can also be diagnosed and fixed without replacing the unit. A contractor can read the error code and tell you whether it's a repair or, in rarer cases, something serious enough to warrant replacement.
