Water Heater Replacement in Denver, CO

Signs the old heater is done

• Water seeping from the tank seam or the bottom of the shell
• Rusty hot water that clears on the cold side
• A heater past the 10 to 15 year range the Department of Energy gives for storage tanks
• Repeated part failures in the same year

Choosing the replacement

Most homes go back with the same fuel and a similar size, which keeps the job simple. Sizing depends on how many people shower back to back, whether there is a large soaking tub, and how much laundry runs at once. Some owners use the swap to look at a tankless model, which changes gas line, venting and electrical needs and is a bigger project.

The Denver permit

Denver Community Planning and Development lists water heaters in single-family and duplex homes as quick permits, applied for online through e-permits. A permitted install gets an inspection of the venting, gas connection and relief valve discharge. Ask whether the plumber pulls the permit as part of the price.

What usually gets updated

A new heater rarely goes in by itself. Common add-ons include:

• A new gas flex connector and shutoff
• A relief valve discharge pipe run to an approved spot
• An expansion tank where the plumbing needs one
• A drain pan if the heater sits above finished space
• Venting corrections, which can come up in houses where the original heater dates back decades

With about 55.5% of Denver housing built before 1980, a plumber may find older venting or connections to bring up to current standards.

What affects the price

Tank size and fuel type, the efficiency of the new unit, how easy the old one is to haul out, any code corrections, and the permit. Heaters in tight closets or finished basements take more labor to remove and set. Ask for a written quote that lists what is included, including disposal of the old tank and whether the permit fee is part of the total.

After the install

Keep the paperwork and warranty card, note the install date on the tank, and flush a few gallons every so often. Denver Water's supply is harder in winter and in the south part of its system, so buildup can vary by address.
