Tankless Water Heater in Castle Pines, CO

Signs to consider tankless

• The tank in the garage or basement is aging and starting to rumble or weep
• Guests or teenagers keep running the hot water out
• You'd like a wall-hung unit and the floor space back
• An existing tankless unit throws codes or struggles on cold mornings
• Hot water output has slowly dropped over a few years

Local conditions in Castle Pines

Castle Pines incorporated in 2008 from the Castle Pines North community, and its housing reflects that: garages, mechanical rooms and exterior walls tend to be close to the water heater, which keeps a new sealed vent short. The bigger question in a newer home is usually gas supply. A tankless burner at full fire can draw several times what a tank does, and Black Hills Energy's meter and the house piping have to keep up with the furnace, range and fireplace at the same time.

Water depends on the address. Castle Pines North Metropolitan District (CPNMD) provides water and wastewater for most of the city, and it buys wholesale water from Highlands Ranch Water each year from October through April, so what comes out of the tap can change with the season. The Village at Castle Pines to the south is served by a separate district that draws on eight groundwater wells, and every home there has a backflow prevention device. CPNMD doesn't publish a hardness figure on the page reviewed, so a quick test helps set a flushing schedule for the heat exchanger.

What affects cost

• Gas line sizing. Upsizing the run from the Black Hills meter is the most common add-on.
• Venting. Sidewall or roof exits, with a condensate drain on condensing units.
• Unit capacity. Larger homes with several baths running at once need more flow.
• Recirculation. Adding a pump or loop for faraway bathrooms adds parts and labor.
• Permit. Water heater replacement is a City 1-Stop permit.

What happens when you call

If you smell gas, leave the house, then call 911 and Black Hills Energy using the emergency number on your gas bill.
