FAQs
What advantages does a tankless water heater offer over a traditional storage‐tank unit?
Tankless (on-demand) water heaters heat water only when you open a tap, eliminating standby losses that occur with a tank. This can cut water-heating energy use by 25–40 %. They also provide virtually endless hot water, free up floor space because they mount on a wall, and last 18–20 years—about twice the life expectancy of a tank. In Gruetli-Laager’s moderate climate, the lower incoming-water temperature drop means the unit works less hard, further boosting efficiency.
How do I know if a tankless system will meet my Gruetli-Laager home’s hot-water demand?
The key is flow rate—the gallons per minute (GPM) of hot water your household uses when multiple fixtures run at once. Our certified technicians perform a sizing visit, adding the flow rates of showers, faucets, and appliances you’re likely to operate simultaneously. We then account for the local groundwater temperature (about 58 °F in Grundy County) to calculate the temperature rise the unit must achieve. If a single unit can’t cover peak demand, we can install tandem units or a dedicated unit for high-use fixtures like a spa tub.
What does the installation process involve, and how long will it take?
1) Site assessment and load calculation; 2) secure permits with the City of Gruetli-Laager and Grundy County Codes; 3) drain and remove the old tank (if present); 4) mount the tankless unit, run venting through an exterior wall or roof, and connect water lines; 5) upgrade or extend gas piping or install a 240-V electrical circuit, as required; 6) pressure-test, flush, and commission the system. For most single-family homes the entire job takes 4–8 hours, so you’ll have hot water again the same day.
Will I need to upgrade my gas line or electrical service?
Possibly. Gas tankless models generally need a ¾″ gas supply line capable of 150–200 k Btu/h, which is larger than what an older tank water heater used. Electric models typically require a dedicated 240-V breaker and 40–60 amps, plus proper wire gauge. During our assessment we measure existing capacity, recommend any upsizing, and include that work—along with venting and condensate drains—in one turnkey quote, so you stay code-compliant without surprises.
How much money can I expect to save by switching to a tankless water heater?
Actual savings vary by usage, but Energy Star® studies show households save $80–$120 per year, or about 25–40 % of water-heating costs. With Gruetli-Laager’s electric rates, payback averages 6–8 years. You may also qualify for up to a $600 federal tax credit (IRC §25C) and occasional TVA or local utility rebates, which shorten payback further. Because the unit lasts nearly twice as long as a tank, you avoid at least one full replacement cost over its lifetime.
What maintenance is required, and do you offer service plans?
Tankless units need an annual flush with white vinegar or a mild descaling solution to remove mineral buildup, especially with Gruetli-Laager’s moderately hard water. The inlet screen should be cleaned every 6–12 months, and the vent inspected for blockages. We offer an affordable maintenance plan that covers yearly flushing, safety inspections, and priority repairs. Most manufacturers provide 12–15-year heat-exchanger warranties when a certified technician performs this maintenance, protecting your investment.
