FAQs
What are the main benefits of switching to a tankless water heater in Gruetli-Laager?
Tankless (on-demand) heaters provide endless hot water, use up to 30 %–40 % less energy than storage tanks, and take up far less space—an advantage in many Gruetli-Laager homes that have limited mechanical-room square footage. Because the heat exchanger only fires when water is needed, standby heat loss is virtually eliminated, giving you lower utility bills year-round. In addition, most tankless units qualify for federal and Tennessee energy-efficiency rebates, which can offset a portion of the purchase price.
How do I determine the correct size (flow rate) for my tankless unit?
Sizing is based on two factors: (1) the total gallons per minute (GPM) of hot water you expect to use simultaneously—e.g., running a shower (2 GPM) and a dishwasher (1.5 GPM) at the same time would require 3.5 GPM—and (2) the temperature rise needed to bring incoming cold water up to your desired hot-water set-point. In Gruetli-Laager, winter ground-water temperature averages about 55 °F. If you prefer 120 °F hot water, you need a 65 °F rise. A typical three-bathroom home here ends up with a 7–9 GPM gas unit or a 18–24 kW electric unit. Our technicians will perform an on-site audit to calculate your exact demand and recommend the proper model so you never run out of hot water.
Will a tankless system handle Gruetli-Laager’s water quality and climate conditions?
Yes. Local municipal and well-water tests show moderate hardness (7–9 grains per gallon). While this is safe for potable use, scale can form on any water-heating surface over time. We install a sediment pre-filter and, when hardness exceeds 10 GPG, a scale-inhibiting cartridge to protect the heat exchanger. Regarding climate, outdoor-rated gas units include built-in freeze protection down to –22 °F, well below Grundy County’s record lows. Indoor models vent through a sealed concentric vent and are not exposed to freezing conditions.
What does the installation process involve and how long does it take?
A standard replacement in an existing mechanical room usually takes one working day. We start by turning off water, gas/electric, and safely draining and removing your old storage tank. Next we mount the compact tankless unit on a wall bracket, run new water isolation valves, and upgrade the gas line to the larger BTU requirement (typically ¾-in. CSST). For electric models, we install the necessary 240-V breakers and copper conductors. Venting is routed through an exterior wall or the roof with Category III stainless or PVC, depending on the model. Finally, we purge air, test for leaks, program the controller, and show you how to operate and maintain your new system.
Are permits and inspections required for a tankless water heater installation in Gruetli-Laager?
Yes. Grundy County enforces the 2018 International Residential Code (IRC). Any change to a fuel-gas line, electrical service, or venting path requires a mechanical/plumbing permit, and the final work must be inspected by the county building official. Our company handles the permit application, schedules the inspection, and provides all manufacturer specification sheets so you remain fully code-compliant and eligible for warranty coverage.
What routine maintenance should I expect and how long will the unit last?
Manufacturers recommend a yearly service that includes flushing the heat exchanger with food-grade vinegar to remove mineral scale, cleaning the inlet filter, and running a diagnostic check. This takes about one hour and significantly extends efficiency. Gas burners should also be vacuumed and inspected. With proper maintenance, quality tankless units last 20–25 years—roughly double the lifespan of a conventional tank. Most brands offer 12-year heat-exchanger and 5-year parts warranties, which we register for you upon installation.
