Tankless Water Heater in Sedalia, CO

Where does Sedalia water come from, and does it matter for a tankless unit?

Sedalia Water and Sanitation District, a small district formed in 1958, took over a water system originally installed by the railroad and serves properties within its boundaries. Homes elsewhere in the 80135 ZIP aren't covered by it. The district's water source and hardness weren't listed in the sources reviewed, so the honest answer is to test. Hardness or other minerals settle in a tankless heat exchanger, and a test tells the plumber whether yearly flushing is enough or whether treatment belongs ahead of the unit. The district office is at (303) 688-2506.

What about sewer and the condensate drain?

Despite its name, the Sedalia district says it does not provide sanitary sewer service, and no other sewer provider was verified. That's relevant to a condensing tankless unit, which produces acidic condensate that has to drain somewhere. Many installers add a neutralizer before the drain line. If your home isn't on municipal sewer, talk to the plumber about where condensate will go and whether a neutralizer makes sense for your private onsite wastewater system.

Who permits the work and what fuel will it use?

Sedalia is unincorporated, so the Douglas County Building Division issues building permits, weekdays 8 a.m. to 5 p.m. The state lists Douglas County as running its own county-wide plumbing inspection program, so plumbing is permitted locally rather than by the state. Gas service wasn't verified for Sedalia; your gas bill shows the utility, and propane homes need a propane-rated unit. Either way, the line must carry a tankless burner at full fire. If you smell gas, leave the house first, then call 911 and your gas utility or propane supplier from outside.

A Sedalia note

Sedalia sits about 8 miles northwest of Castle Rock on U.S. 85. Rural outages stop gas tankless units, which need power for their controls, so if the lights go out often, ask about backup power or weigh a storage tank instead. Winter water also arrives colder, which lowers how much hot water any tankless unit can deliver at once, so the plumber sizes for the coldest months rather than summer. Altitude trims burner output as well, and the maker's derating figures belong in that sizing.
