What Greenwood Village's water does to a water heater
When water is heated, the calcium and magnesium in it drop out as sediment and settle on the bottom of the tank. The burner or lower element then has to heat through that layer, so the heater runs longer, pops and rumbles, and wears faster. Greenwood Village gets Denver Water's water through local distributors, and it averaged about 105 mg/L of hardness in 2025 (about 6 grains per gallon), a little harder in winter. Moderate scale. A yearly flush and an anode check every few years keep a tank close to its rated life.
Denver Water through local districts
Water in Greenwood Village comes from Denver Water, delivered through distributors that include the City of Greenwood Village and the Cherry Creek Village Water District, so your bill may name the district rather than Denver Water. At about 105 mg/L of hardness, a tank builds moderate sediment, and a yearly flush keeps it close to its rated life. Larger houses sometimes have two heaters or a high-capacity one, and a replacement is the time to make sure the size still fits the household.
Repair or replace?
Under about eight years old, with a failed part like a thermocouple, gas valve, heating element, or thermostat, a repair usually makes sense. At about ten years or older, or with any leak from the tank itself, replacement is the better money: a leaking tank can't be fixed. You get the price before any work starts, and most replacements are done the same day they're quoted, with the old unit hauled away. A replacement is also the time to check whether you need an expansion tank (when one is required).
Gas or electric, tank or tankless
We repair and replace both gas and electric water heaters, standard tanks and tankless units. Tankless works well at this hardness. Descale it about once a year so scale doesn't choke the heat exchanger.
Make the next one last
- Flush the tank once a year to clear sediment
- Check the anode rod every few years
- Descale a tankless unit about once a year
- Know where the cold-water shutoff on top of the heater is, and how to turn the heater off, before you need to
