Tankless water heaters in Greeley: Atmos rebates and altitude
Greeley’s gas utility is Atmos Energy (Atmos’s April 2026 tariff), and Atmos still pays rebates on efficient gas water heaters. Xcel, which supplies gas in most of the surrounding area, offers none for gas models.
| Atmos Energy rebate, 2026 | Efficiency required | Rebate |
|---|---|---|
| Natural gas tankless | UEF of 0.95 or higher | 80% of total cost, up to $800 |
| Natural gas tank, 55 gallons or less | UEF of 0.86 or higher | 80% of total cost, up to $700 |
Apply within 60 days of installation; rebates last while Atmos’s funding does. ENERGY STAR describes gas tankless models that meet its own 0.95 UEF minimum as condensing, so a qualifying unit typically vents through plastic pipe and needs a condensate drain.
Greeley’s USGS reference point is 4,674 feet, the lowest of the towns we serve but well above the 2,000 feet where the fuel gas code requires gas flow to be adjusted. Rinnai’s 2,001 to 5,200 foot setting covers Greeley, and there one 199,000 Btu/h natural gas model derates to 170,000 Btu/h, about 15% less, so it delivers fewer gallons per minute at the same temperature rise. Our guide to what size water heater you need covers sizing for that.
Replacing a water heater in an older Greeley home
Greeley is the largest city we serve after Fort Collins, with about 115,073 residents (U.S. Census Bureau, Vintage 2025 estimate), and its housing is older than in the newer towns nearby. Of its 41,784 homes, 45.6% were built before 1980 and 16.3% in 2010 or later, and the median home dates from 1985 (U.S. Census Bureau, ACS 2020-2024 5-year estimates).
On a replacement, especially in an older house, we check:
- Venting. A heater that vents into a chimney or metal flue has to draft properly, since exhaust spilling indoors is a carbon monoxide risk.
- Gas shutoff and sediment trap. Code requires a shutoff in the same room within 6 feet and a sediment trap at the inlet; missing ones go on the quote.
- Replacement exceptions. A drain pan isn’t required where none existed, and Colorado’s rule to pipe relief valve discharge to a drain or outdoors exempts replacements.
Greeley water heater permits and the 2027 license rule
The City of Greeley lists water heaters among the work that needs a permit. Its Building Inspection Division issues them from 1100 10th Street (970-350-9830).
There’s no flat water heater fee: the permit fee is based on the project’s estimated construction value, using the ICC’s latest Building Valuation Data, plus a plan review fee of 65% of it and 2.8% for card payments.
Homeowners doing their own work may need a notarized 2026 Homeowner Affidavit. Its plumbing clause requires that you live in the home as your primary residence, that it isn’t for sale, resale or rent or generally open to the public, and that the work is inspected. Anyone paid for the work must be licensed or registered with the City, and from January 1, 2027, all trades will need a City of Greeley license to pull permits, according to an August 2026 City announcement.
Is Greeley’s water hard?
Greeley does not publish a hardness figure in the sources we checked; its 2026 drinking water quality report, covering 2025, lists none. Look for one in the City’s annual water quality report, or have your water tested. For a tankless unit, compare the result with the manual; Rinnai’s condensing models allow up to 200 mg/L of hardness and exclude scale damage from the warranty.
What happens when you call
Tell us the fuel, the heater’s age and what it’s doing. A licensed plumber, covered by liability insurance, diagnoses it on site and gives you a written, itemized quote, and if repair is the better value, we say so. On a replacement we pull the Greeley permit, install and test the heater, haul the old one away and schedule the City inspection.
