What is a heat pump water heater?

A heat pump water heater is an electric water heater that heats water by moving heat rather than generating it directly. Instead of running electricity through resistance elements like a conventional electric tank, it uses a small heat pump — the same technology found in a refrigerator or air conditioner, run in reverse — to pull warmth out of the surrounding air and transfer it into the water. Because moving heat is far more efficient than creating it, these units use dramatically less electricity.

Nearly every unit we install is a hybrid heat pump water heater, which combines the efficient heat pump with backup electric-resistance elements. On ordinary days the heat pump does the work; during heavy demand the backup elements can kick in so you never run short on hot water. As a pleasant side effect, the unit also dehumidifies and slightly cools the space it sits in — a welcome bonus in a Denver basement.

How much does a heat pump water heater cost in Denver?

A professionally installed heat pump water heater in the Denver metro typically costs $5,000 to $7,500 before the Xcel rebate. The final number depends mostly on your electrical situation and the tank size you need. Our pricing is all-in — equipment, labor, permits, and cleanup.

After the Xcel rebate of up to about $1,500 is credited, most Denver homeowners pay noticeably less out of pocket. See our Denver cost breakdown for a line-by-line look.

How does the Xcel rebate work?

Xcel Energy offers a rebate for qualifying heat pump water heaters, and Denver Heat Pump Water Heaters credits it directly on your invoice so you never wait for a check. The standard rebate is $750, and Xcel customers whose home heat is natural gas qualify for a bonus bringing it to roughly $1,500. Because we are a participating Xcel contractor, we handle the paperwork and apply the amount upfront as an instant discount.

• Standard rebate: about $750 for qualifying hybrid heat pump water heaters.
• Gas-heat bonus: up to about $1,500 for Xcel customers switching from a natural-gas water heater.
• Credited upfront: we deduct it from your invoice — no rebate forms to mail, no waiting.

How much can it save me?

A heat pump water heater can use up to about 70% less energy than a standard electric-resistance water heater, which is where the bulk of the savings come from. For a typical Denver household, that efficiency translates into meaningfully lower monthly utility bills, and the gap widens as electricity is used more sparingly. Over the 10–15 year life of the unit, those savings add up to a substantial return against the higher upfront cost.

What size do I need (50 vs 65 vs 80 gallon)?

The right tank size depends on how many people live in your home and your peak hot-water demand. Most Denver homes land on a 65-gallon hybrid, which comfortably serves a typical family, while smaller households do fine with a 50-gallon and larger homes with high simultaneous demand step up to 80 gallons.

Where should it be installed?

A heat pump water heater should be installed in a space with enough surrounding air for it to draw heat from — typically a basement, utility room, or garage with roughly 700–1,000 cubic feet of air or a louvered door. Denver’s prevalence of unfinished basements makes placement straightforward for most homes. The unit needs a nearby condensate drain and a 240V electrical connection, both of which we handle as part of the install.

Which brands are best?

We prefer and most often install the Rheem ProTerra, which offers an excellent balance of efficiency, reliability, and quiet operation. We also install A.O. Smith Voltex, Bradford White AeroTherm, and State units depending on availability and your preferences.

• Rheem ProTerra — our preferred unit; efficient, quiet, and well-supported.
• A.O. Smith Voltex — strong performance and widely available.
• Bradford White AeroTherm — durable, contractor-trusted build.
• State — a reliable value option.

How long does installation take?

Most heat pump water heater installations are completed in a single day. A straightforward swap where the electrical is already in place often takes just a few hours, while jobs that require a new 240V circuit or panel upgrade run longer. We pull the permit, install the unit, route the condensate drain, haul away your old water heater, and schedule the inspection. See our installation page for the step-by-step process.

Is it worth it in Colorado?

Yes — for most Denver-area homes a heat pump water heater is well worth it. Between the up-to-70% energy savings, the Xcel rebate of up to about $1,500 credited upfront, and a 10–15 year lifespan, the economics are compelling along the Front Range. Colorado’s dry climate and the abundance of basements and utility rooms with ample air make placement easy, and the added dehumidification is a bonus. If your current water heater is aging, replacing it with a hybrid heat pump model is one of the highest-value upgrades you can make. Explore your options on our water heater replacement page.
