Our installed pricing starts at $7,500 for a 50-gallon system and runs to roughly $9,700 for an 80-gallon Bosch, depending on the model and what the existing setup requires. After the $2,250 Xcel Energy rebate and the Colorado tax credit pass-through, most Denver metro homeowners land between $5,167 and $7,367 net. Income-qualified households stacking HEAR can come in closer to $3,400. The variables that move the number are whether a new 240V circuit is needed, whether there’s a gravity drain for condensate, and whether the closet needs modification for airflow. We break the line items down further in our Denver HPWH cost guide.

It depends entirely on which unit you buy, and this is the single most important question on this page. The Bosch GreenTronic 7000 T runs its heat pump down to 5 °F ambient, so it keeps working as a heat pump through a Denver cold snap. The Rheem ProTerra’s lower limit is 37 °F — below that it switches to electric resistance backup, which still makes plenty of hot water but at roughly four times the operating cost. If your water heater lives in an attached but unheated garage, we will steer you to the Bosch. If it lives in a conditioned basement, either brand is a fine choice.

No. The federal 25C Energy Efficient Home Improvement Credit — the one worth up to $2,000 on a heat pump water heater — was terminated by the One Big Beautiful Bill Act (P.L. 119-21), signed July 4, 2025, for property placed in service after December 31, 2025. There is no reduced 2026 rate and no phase-down. The Xcel Energy rebate, the Colorado state credit, and HEAR are all unaffected and still available. Be skeptical of any 2026 quote that still includes a federal credit line item.

Use first-hour rating rather than tank size. A household of one or two is comfortable on a 50-gallon (roughly 67–69 gallons in the first hour). Three to four people, especially with back-to-back morning showers, want the 65-gallon. Five or more, or a home with a large soaking tub, should go 80-gallon. Heat pump water heaters recover more slowly than gas, so sizing up one step from your old gas tank is usually the right instinct — a 65-gallon heat pump is the honest replacement for a 50-gallon gas unit.

Rheem’s ProTerra plug-in models run on a standard 120V, 15-amp circuit, which often means no electrician and no panel work at all — a meaningful saving when you’re converting from gas and there’s no 240V anywhere nearby. The trade-off is efficiency and recovery: the 120V 65-gallon is 3.33 UEF with a 63-gallon first-hour rating, versus 4.05 UEF and 77 gallons for the 240V version. If the circuit run is short and your panel has room, the 240V unit is worth it. If it isn’t, the plug-in is a genuinely good answer rather than a compromise.

Both brands run in the mid-to-high 40s dB(A) — Rheem publishes 45 dB(A), Bosch 49 dB(A). That’s comparable to a quiet refrigerator or a bathroom fan on low, but it is a real sound, and it’s a compressor sound rather than a hum. Nobody regrets one in a basement utility room or a garage. Directly below a bedroom or beside a home office is worth thinking about. Both units also need roughly 700–1,000 cubic feet of air around them, or a louvered door or duct kit, which rules out a sealed closet without modification.

A straightforward replacement where a suitable circuit already exists is typically 5–8 hours, one day. Add half a day if we’re running a new 240V circuit, converting from gas, or modifying a closet for airflow. We schedule the city inspection before we leave, and you keep hot water the same evening in nearly every case.

Yes, entirely. We file the Xcel application and the Colorado tax credit documentation ourselves, and the $2,250 rebate is credited directly on your invoice rather than reimbursed later. You never front the rebate money and you never chase a check. The only requirement on your end is an active Xcel Energy gas account — gas-only or gas plus electric. Electric-only Xcel customers are not eligible for this particular rebate.

Usually, yes. We stock the common Bosch and Rheem sizes and hold ASAP slots for no-hot-water emergencies. If your tank has already failed, call (303) 219-1000 rather than booking online — we’ll triage it same day. If you’re replacing proactively, booking a consultation online is the faster path and gets you a firm install date typically within the week.

Expect 10–15 years, similar to a quality conventional tank, with a 10-year tank and parts warranty from both manufacturers. Maintenance is light: rinse the air filter every few months (it’s a two-minute job and the app reminds you), check the anode rod around year five, and flush the tank annually — Denver metro water is moderately hard, so sediment is a real factor. We offer a maintenance plan, but nothing about it is mandatory to keep your warranty.

Yes, and many Denver homeowners consider it a feature. The unit pulls heat and moisture out of the surrounding air, so it acts as a modest dehumidifier and produces a small cooling effect in the room it occupies. In an already-cold basement in January that’s a downside worth designing around; in a muggy July it’s free dehumidification in exactly the room that needs it.

Financially it’s a closer call than the switch from electric resistance, because Colorado natural gas is inexpensive — the annual operating difference is on the order of $70. The case for switching from gas is usually about something else: eliminating a combustion appliance and its flue, freeing up a chimney or venting run, avoiding a new gas line on an addition or ADU, pairing the water heater with solar you already have, or reducing your home’s carbon footprint. If your gas tank is healthy and you’re purely optimizing dollars, we’ll tell you to wait — and we do tell people that. If endless hot water matters more to you than efficiency, a tankless system may be the better fit.
