FAQs
How does a tankless water heater work and why should I consider one for my Collegedale home?
A tankless (on-demand) water heater uses high-powered gas burners or electric elements to heat water only when you open a hot-water tap. Because there is no storage tank continually reheating 40–80 gallons, it can cut standby energy losses by 24–34 %. Homeowners in Collegedale appreciate three big advantages: endless hot water, up to 50 % lower utility bills versus an older tank, and a unit that usually lasts 18–20 years—nearly double the lifespan of a conventional heater.
What size or capacity tankless unit do I need?
Sizing is based on two factors: 1) the peak flow rate you need (measured in gallons per minute) and 2) the temperature rise required to get incoming cold water up to your preferred 120 °F. In Collegedale, ground-water temperature averages about 55 °F, so you need a 65 °F rise. For a typical household running two showers and a dishwasher at once, we usually recommend a 9–11 GPM gas unit or a 27 kW electric unit. During the in-home consultation we’ll calculate your exact demand, look at gas line or electrical service capacity, and propose the right model so you never run out of hot water.
How much does professional tankless water heater installation cost in Collegedale?
Installed prices generally range from $2,600–$4,500 for gas models and $2,000–$3,700 for whole-house electric models. The final cost depends on the unit’s capacity, whether we have to upsize gas lines or electrical service, venting requirements, permits, and any code upgrades (e.g., seismic straps, drain pan, or condensate neutralizer). We provide a written quote that includes labor, materials, removal and recycling of your old tank, permit fees, and the first year of annual flush service.
How long does installation take and will I be without hot water?
Most residential replacements are completed in one working day. We shut off the old tank in the morning, mount the new wall-hung unit, run venting and gas/electrical connections, flush the lines, and program the controller. Your hot water is usually restored by late afternoon. If extensive gas-line upgrades or panel work are required, we may schedule a second day, but we will notify you in advance and, if possible, leave the old tank in service overnight.
Do I need a permit in Collegedale, and do you handle the paperwork?
Yes. The City of Collegedale and Hamilton County require plumbing and, for gas units, mechanical permits. Electric units may need an electrical permit as well. As a licensed and insured contractor, we pull all necessary permits, coordinate any inspections, and ensure the installation meets the 2021 International Plumbing and Fuel Gas Codes as adopted locally. This protects your home, keeps the warranty valid, and may even help with future resale value.
What maintenance does a tankless water heater require and can you provide it?
Tankless units need an annual or bi-annual service: descaling/flushing the heat exchanger with food-grade vinegar (or a manufacturer-approved solution), cleaning the inlet filter, and checking the burner, vent, and condensate line. In Collegedale’s moderately hard water (6–9 grains per gallon), we recommend yearly service to prevent mineral buildup and maintain efficiency. We offer an affordable maintenance plan that covers the flush, safety inspection, and firmware updates, keeping your warranty compliant and extending the life of the unit.
