FAQs
How does a tankless water heater save energy compared with a conventional storage tank?
Standard tanks keep 40-50 gallons of water hot 24/7, constantly cycling the burner or elements and losing heat through the tank walls ("stand-by loss"). A tankless unit only fires when a hot-water tap is opened. Because there is no stand-by loss, households in Gruetli-Laager typically see energy-use reductions of 25-40 %, and in many cases utility bills drop $75–$150 per year, depending on usage and local electric or propane rates.
What size (flow rate) tankless water heater do I need for my Gruetli-Laager home?
Sizing is based on two factors: (1) the maximum gallons per minute (GPM) you’ll need at one time, and (2) the temperature rise between the incoming cold-water temperature and your desired hot-water temperature. In Gruetli-Laager, incoming water averages 55 °F. To reach 120 °F you need a 65 °F rise. A typical two-bath home that might run one shower (2.0 GPM), one sink (1.0 GPM) and a dishwasher (1.5 GPM) simultaneously should choose a unit that can supply roughly 5 GPM at a 65 °F rise—usually a 180,000 BTU gas model or a 27 kW electric model. Our technicians will calculate your exact demand during the in-home consultation.
Will a tankless heater work with my existing gas, propane, or electrical service?
Often yes, but an assessment is required. High-efficiency gas models need a ¾-inch (or sometimes 1-inch) gas line and a Category III or PVC vent. Propane systems require proper regulators and clearances. Electric tankless units typically need a 200-amp panel and two to three 40-60 amp double-pole breakers. During our free estimate we inspect your current plumbing, venting and electrical/gas supply; if upgrades are necessary we outline the scope and cost before work begins.
How long does installation take, and will I be without hot water?
A straightforward replacement usually takes 4–6 hours: shutting off utilities, removing the old tank, mounting the new unit, making water, gas or electric connections, then testing and flushing. More complex jobs (e.g., panel upgrades or new vent runs) can extend installation to a full day. You will be without hot water only during the swap-over period—generally less than half a day—and we schedule at your convenience to minimize disruption.
What routine maintenance is required on a tankless system in Grundy County?
Gruetli-Laager’s water has moderate mineral content, so we recommend an annual descaling/flush. We connect isolation valves, circulate a vinegar solution for 30–45 minutes, then rinse the heat exchanger. Cleaning the inlet filter and checking the condensate drain (for condensing gas models) is also part of the visit. With proper maintenance, units commonly last 20+ years—double the life expectancy of most storage tanks.
Are there rebates or incentives for installing an energy-efficient tankless unit?
Yes. Through 2032, the federal Energy Efficient Home Improvement Credit refunds 30 % of the equipment and installation cost—up to $600 for gas units or $2,000 for highly efficient electric heat-pump water heaters. The Tennessee Valley Authority’s EnergyRight program often offers $150–$300 in bill credits for qualifying upgrades, and Gruetli-Laager Utility District periodically runs promotional rebates. We handle all paperwork and supply the documentation you need for tax filing and utility submissions.
