FAQs
Why should I choose a tankless water heater for my Englewood home?
Tankless units heat water on demand, which means unlimited hot water, up to 40 % lower energy costs compared with storage tanks, and a much smaller footprint—important in Englewood’s many space-conscious homes. Because they run only when you open a tap, the heat exchangers experience less standby loss, helping them last 20+ years with proper maintenance.
How do I size a tankless system for my household?
Sizing is based on two factors: 1) peak flow rate (gallons per minute) required by simultaneous fixtures and 2) the temperature rise between Englewood’s incoming groundwater (≈55 °F) and your desired hot-water setpoint (~120 °F). For example, two showers and a dishwasher running together might require 6–7 GPM. We calculate this and recommend a unit, typically 150–199 k BTU for a three-bath Englewood home.
Do I need any permits or code inspections in Englewood?
Yes. The City of Englewood Building Division requires a plumbing/mechanical permit for water-heater replacement, plus an electrical permit if we are adding or upgrading circuits. After installation, a city inspector will verify gas line sizing, venting, condensate drainage, electric bonding, and seismic strapping. We handle all permit applications and schedule inspections for you.
Will my existing gas line and venting work with a tankless heater?
Often, upgrades are necessary. High-efficiency condensing units may need ¾-inch or larger gas supply and Category IV PVC or polypropylene venting that terminates outside. Non-condensing models use stainless steel Category III venting. During our free on-site assessment, we measure line pressure, pipe diameter, and vent path to provide a firm quote that includes any required modifications.
What maintenance does a tankless water heater require in Englewood’s water conditions?
The Denver metro area’s water is moderately hard (110–140 ppm). We recommend a professional annual service that flushes the heat exchanger with food-grade vinegar or citric acid, cleans the inlet filter, and checks the combustion settings. If hardness is above 7 gpg, adding a scale inhibitor cartridge or whole-home softener can double the life of the unit.
How long does installation take and what will it cost?
A straightforward replacement typically takes one working day (6–8 hours). If gas or venting upgrades are needed, plan on an additional half day. Pricing for a fully installed, premium-brand condensing tankless heater in Englewood averages $3,200–$4,800 before utility rebates. Xcel Energy currently offers up to $400 in rebates for ENERGY STAR® certified models, and we file the paperwork on your behalf.
