FAQs
What are the main benefits of switching to a tankless water heater for my Greenback home?
Tankless units heat water on demand, so you never run out of hot water and avoid the standby energy losses of a storage tank. They’re typically 25–40 % more energy-efficient, which can lower monthly utility bills. Tankless models are wall-mounted, freeing up floor space, and their average life span of 20+ years is nearly double that of conventional tanks. Many Greenback homeowners also appreciate the reduced risk of leaks because there is no large reservoir of stored water.
How do I determine the correct size (flow rate) of tankless water heater I need?
Proper sizing is based on the total gallons per minute (GPM) of hot water your household may use simultaneously and the required temperature rise (difference between incoming water temperature and desired output). We start by listing fixtures that may run at the same time—e.g., one shower (2.0 GPM) plus a kitchen sink (1.5 GPM) equals 3.5 GPM. In Greenback, incoming water averages about 55 °F, so achieving a 120 °F outlet requires a 65 °F rise. Our technicians perform these calculations onsite and recommend a unit (e.g., 7.5 GPM natural gas model) that comfortably meets peak demand without oversizing.
What does the installation process involve and how long does it take?
A typical residential installation takes 4–8 hours. We begin by shutting off water, gas, and electricity to remove the old tank. Next, we mount the tankless unit on an exterior or interior wall, run new venting (usually direct-vent concentric or PVC), and, if needed, upsize the gas line or install a dedicated 240 V circuit for electric models. We then connect water lines with isolation valves, purge air, test for leaks, and program the control panel. Before leaving, we show you how to adjust temperature and flush the heat exchanger. All work complies with Greenback building codes and manufacturer specs.
Will I need to upgrade my gas line or electrical service?
Often, yes. Gas tankless heaters require a larger BTU input—up to 199,000 BTU—so your existing 1/2-inch gas line may need to be upsized to 3/4-inch or 1-inch to maintain proper pressure. Electric tankless units draw 60–120 amps and may require multiple 240 V breakers. During our free in-home assessment, we measure gas line capacity and panel load to provide an accurate quote that includes any necessary upgrades. All modifications are permitted and inspected to ensure safety and code compliance.
How much maintenance does a tankless water heater require in Greenback?
Maintenance is straightforward: flush the heat exchanger with a 60 minute white-vinegar or descaling solution once a year (twice if your water hardness exceeds 12 grains per gallon). The flush removes mineral buildup that can reduce efficiency. We install isolation valves and a service port to make this quick—most homeowners can DIY or schedule a $99 service visit. You should also clean the inlet screen filter every 6 months. Following these steps preserves your warranty and keeps efficiency near peak levels.
What is the expected lifespan and what warranties do you offer?
With proper maintenance, a quality tankless unit lasts 20–25 years. Manufacturers typically back the heat exchanger for 12–15 years, other parts for 5 years, and labor for 1 year. Our company adds a 5-year labor warranty and offers optional extended coverage up to 10 years. We register your unit with the manufacturer, keep digital records of service history, and handle any warranty claims on your behalf.
