FAQs
What are the main advantages of upgrading to a tankless water heater?
A tankless (on-demand) water heater produces hot water only when you open a tap, eliminating the standby heat loss of a storage tank. Most Englewood homeowners see energy-bill savings of 24–40 %. You also get virtually endless hot water, freeing you from the “running out” problem of a tank. Tankless units mount on a wall, gaining 10–20 ft² of floor space, and they typically last 20+ years—about twice as long as a conventional tank. Added benefits include more precise temperature control, lower risk of tank leaks/floods, and compatible smart-home monitoring options.
Will a tankless system work with Englewood’s cold winter groundwater temperatures?
Yes. Modern gas and electric tankless heaters are engineered to handle incoming water as cold as 40 °F, which is common along the Front Range in January. The key is proper sizing: the colder the inlet temperature, the higher the BTU or kilowatt rating you need to achieve your desired flow rate. During our in-home assessment we measure your winter groundwater temperature, count simultaneous fixtures, and recommend a unit—often 180–199 k BTU for gas or 27–36 kW for electric—to deliver 2.5–5 GPM of 120 °F water even on the chilliest mornings.
How do I determine the right size tankless water heater for my household?
Sizing is based on peak demand, not tank volume. We add the flow rates (in gallons per minute, GPM) of the fixtures you’re likely to run at once—e.g., shower 2.5 GPM + kitchen faucet 1.5 GPM + washing machine 2.0 GPM = 6 GPM. Then we calculate the temperature rise: desired hot-water temp (120 °F) minus winter inlet temp (~50 °F), or 70 °F. A gas unit that produces 6 GPM at a 70 °F rise would need roughly 180 k BTU. Electric models require similar math but use kilowatt rating instead. Our plumbers handle the calculation and show you options that balance performance, efficiency, and budget.
What is involved in converting from a storage-tank heater to a tankless model, and how long does it take?
A typical upgrade in Englewood takes one working day. We 1) drain and remove the old tank, 2) mount the new tankless unit on a wall or bracket, 3) upsize the gas line or install a dedicated 240-V circuit (electric models), 4) add Category III/IV stainless venting or concentric PVC intake/exhaust through the sidewall or roof, 5) connect water lines with backflow and isolation valves, and 6) program and test the unit. Permits and a city inspection are included. More complex jobs—relocating the heater, running a long vent, or upgrading the home’s gas meter—can extend the project to two days.
What maintenance does a tankless water heater require in Englewood?
Denver-area water averages 8–12 grains per gallon, so mineral scale is our main concern. Manufacturers recommend flushing the heat exchanger with a vinegar solution or citric-acid descaler once a year (twice if you have very hard water). The service takes 45–60 minutes and keeps efficiency high while preventing costly scale damage. You should also clean the inlet screen filter quarterly and check the vent for obstructions. We offer an affordable annual maintenance plan that includes flushing, combustion analysis, firmware updates, and full safety inspection.
Are there rebates, tax credits, or financing options for tankless installations in Englewood?
Absolutely. Xcel Energy currently offers residential rebates of $200–$400 for qualifying high-efficiency gas tankless units. Under the federal Inflation Reduction Act (IRA), ENERGY STAR certified gas tankless heaters with ≥0.95 UEF qualify for a 30 % tax credit up to $600. Electric heat-pump water heaters carry a credit up to $2,000. Many Englewood banks and credit unions provide low-interest home-improvement loans, and our company partners with financing programs that let you spread payments over 6–60 months. We complete all rebate paperwork and supply the documentation needed for your tax preparer.
