Water Heater Questions, Answered

$1,450–$2,400 installed for a standard 40–50 gallon gas or electric tank including permit, code corrections and haul-away. Power-vent gas $2,200–$3,200, hybrid heat pump $3,400–$5,200 before rebates, tankless conversion $4,200–$6,800. Full breakdown on our cost guide.

Scope, almost always. Permit, expansion tank, T&P discharge correction, venting, gas line upsizing and disposal are either included or they are not. Get the model number and the six inclusions in writing from each bidder.

Yes, a flat fee, and it is credited toward the repair or replacement if you go ahead. You know the number before we dispatch.

Yes, on replacements and upgrades. We will also identify current Xcel Energy, City of Denver and federal incentives that apply to your chosen unit.

If the tank itself leaks, replace — there is no repair for a corroded vessel. Otherwise: under eight years with a repair under about $400, repair. Past twelve years, replace. In between, compare the repair against half the installed cost of a new unit.

Gas tanks 8–12 years, electric tanks 10–15, hybrid heat pumps 13–15, tankless 18–20. Annual flushing and anode replacement is the difference between the bottom and top of each range.

Read the serial number on the rating plate. Most manufacturers encode the month and year in the first four characters — for example, a serial beginning 0417 often means April 2017. Conventions differ by brand; send us a photo and we will tell you.

Rarely. At that age the anode is long gone and the tank steel is corroding, so you are spending on a component while the vessel is the thing failing.

Gas: the pilot is out, the thermocouple has failed, or a safety has shut the unit down — often due to a blocked flue. Electric: a tripped breaker, a tripped ECO reset, or a failed upper element or thermostat. See water heater repair.

A failed lower element on an electric unit, a broken dip tube mixing cold into the top of the tank, heavy sediment reducing usable capacity, or simply a tank that is undersized for the household.

Water flashing to steam beneath a sediment layer on the tank floor. Flush it before the trapped heat cracks the glass lining. See maintenance and flushing.

Sulfate-reducing bacteria reacting with a magnesium anode rod. Switching to an aluminum-zinc or powered anode, with a tank sanitization, fixes it in most homes. See anode rod replacement.

The anode rod is consumed and the tank's steel is corroding. This is usually the final warning before a leak. Plan a replacement now rather than after the basement is wet.

The tank is reaching relief pressure or temperature. In Denver the usual cause is thermal expansion on a closed system with no working expansion tank, or static pressure above 80 psi. Never cap the valve.

The ECO high-limit trips near 180°F. Repeated trips mean a shorted element or stuck thermostat contacts. Stop resetting it and have it diagnosed — that switch is the last safety before dangerous temperatures.

Yes. The City and County of Denver requires a plumbing permit and inspects the installation. We pull it and meet the inspector.

On closed systems, yes — meaning any home with a pressure-reducing valve or backflow preventer, which covers most Denver homes. Its air charge must match your measured static water pressure.

120°F. Hot enough to limit bacterial growth, cool enough to reduce scald risk and standby loss.

Not always. Efficiency standards changed tank dimensions in 2015, so a same-capacity unit can be two to four inches taller and wider. We measure the opening, the closet header and the vent clearance before ordering.

Colorado allows homeowners to perform work on their own owner-occupied residence in many cases, but the permit and inspection still apply, and gas connections, venting and relief piping carry real safety consequences. An uninspected install can also complicate an insurance claim or a future sale.

Usually. We hold same-day slots for no-hot-water calls and stock the common sizes on the truck.
