Tankless Water Heater in Dacono, CO

Who issues the permit in Dacono?

The City of Dacono handles building permits through its Community Development department, with building services contracted to SAFEbuilt. Water-heating equipment is listed among work that triggers a permit, and a tankless swap usually also involves gas piping and a new vent that the inspector will want to see. The permit technician and Community Development staff can be reached at 303-833-2317. In most cases the installing plumber files the application and schedules the inspection, so you don't need to visit City Hall at 512 Cherry Ave yourself.

Is the gas supply up to a tankless burner?

Black Hills Energy is the gas utility in Dacono. A whole-house tankless unit can draw several times the gas of a storage tank at full fire, and it does so in short bursts, which is when an undersized line shows up as ignition faults or fluctuating temperature. Before choosing a model, a plumber adds up every gas appliance in the house and measures the pipe from the meter. Some homes need a larger line for part of the run. Because the metro area sits around a mile high, the unit's altitude derating also factors in. If you smell gas at any time, leave the house first, then call 911 and Black Hills Energy using the number on your gas bill.

What about Dacono's water?

The City runs its own water department under Public Works, with customer service at 303-833-2317, ext. 121. The City doesn't post a hardness figure on the pages reviewed, so a simple home test is the best guide for how often to flush the heat exchanger. Most manufacturers recommend at least once a year. Isolation valves on the hot and cold lines make that job easier and are worth adding during the install. Sewer service in Dacono comes from St. Vrain Sanitation District, which matters if you choose a condensing unit: its condensate drain needs a proper place to discharge into household plumbing.

A local note

Dacono was settled by coal miners in 1901 and is one of the Carbon Valley Tri-Towns with Frederick and Firestone. Older homes near the original town site may vent the water heater through a chimney shared with the furnace, while newer subdivisions usually have a garage wall close by for a short, simple vent.
