Most Denver hot water heaters last 8-12 years. The warning signs are predictable: rusty water out the hot tap, popping or rumbling sounds from sediment, the pilot won't stay lit, or you find a wet spot at the base. By the time the tank visibly leaks, the failure is hours away, replacement is no longer optional. We dispatch with the right unit and the right gas/electric/venting hardware on the truck.
Tank Replacement: 40, 50, 75 Gallon
Most Denver homes run a 40 or 50 gallon gas tank in the basement or utility closet, with a few homes (especially Highlands Ranch and newer Aurora subdivisions) running 75-gallon units for households with multiple bathrooms. Replacing like-for-like is the fastest path: we shut off gas and water, drain the old unit, swap the tank, reconnect the gas line with new flex connectors, install the T&P relief valve, fill, purge air, and relight the pilot. Most replacements take 2-3 hours start to finish. We pull the Denver permit on the same call and schedule the city inspector. We reconnect the unit with code-compliant natural gas piping and new flex connectors.
Tankless Water Heater Conversion
Converting from a tank to a tankless unit isn't a like-for-like swap. Most 3/4" gas lines feeding a tank heater can't support a tankless unit pulling 199,000 BTU, we run a dedicated 1" gas line from the meter when required. Tankless also needs Category III stainless venting (Rinnai, Navien specifications), proper combustion air, and a condensate drain for high-efficiency units. Expect the conversion to take a full day. The payoff: endless hot water, smaller footprint, and roughly half the standby energy loss of a tank. We won't push a conversion if your existing tank is two years old and properly sized, but for a 10+ year old unit feeding a busy household, the math usually works. See our dedicated tankless water heater installation page for the sizing and venting detail.
Electric vs Gas: Which to Replace With
If you currently have a gas water heater and the gas line is sized right, replacing with gas is almost always cheaper to operate. Electric tank units cost more per gallon of hot water in Denver's utility rates and recover slower. Heat pump water heaters (hybrid electric) are the exception, they're 2-3x more efficient than standard electric and qualify for federal rebates and Xcel rebates in Colorado. We size and install heat pumps when the basement has enough ambient air volume to support them (250+ cubic feet around the unit). For tight closets, stick with gas or tankless.
Permit, Code, and the Stuff Inspectors Look At
Every water heater replacement in Denver requires a permit and an inspection. The inspector checks for: sediment trap on the gas line, T&P discharge piped to within 6 inches of the floor or drain, expansion tank on the cold supply, seismic strapping in some jurisdictions, and proper combustion air for gas units. We install all of these to spec on every replacement, no calls back six months later when a different plumber points out the expansion tank that should have been there from day one. Homeowners across Aurora face the same inspection checklist.
