FAQs
What are the main advantages of installing a tankless water heater in my Reliance home?
Tankless units heat water only when you open a tap, eliminating standby heat loss common with storage tanks. This can reduce energy consumption by 25–40 %. Because there is no tank, you gain space and never “run out” of hot water—perfect for large families or homes with soaking tubs. Tankless heaters also have a service life of 18–25 years, roughly double that of most tank models, and many come with longer factory warranties. Finally, their modular design allows most components to be replaced individually, which simplifies repairs and reduces waste.
How do I determine the correct size (flow rate) of tankless water heater for my household?
Sizing is based on two factors: (1) the combined flow rate (gallons per minute, or GPM) of fixtures you expect to run simultaneously, and (2) the required temperature rise (the difference between incoming groundwater temperature and your desired hot-water setpoint). Endless Supply Plumbing performs a free on-site evaluation to inventory fixtures, measure incoming water temperature in Reliance, and calculate peak demand. As a rule of thumb, a three-bathroom household that may run two showers and a dishwasher at once usually needs a 9–10 GPM gas unit or a 7–8 GPM electric unit. We provide a written load calculation so you know the recommendation is tailored to your home, not just a one-size-fits-all guess.
What does a typical tankless water heater installation cost, and are rebates available in Reliance?
Installed prices vary with fuel type, venting layout, and any gas-line or electrical upgrades. For most single-family homes, Endless Supply Plumbing quotes $3,200–$4,800 for a high-efficiency gas unit and $2,600–$3,900 for a whole-house electric model, including removal of the old tank, permits, venting materials, and labor. Local utility companies often offer $150–$400 rebates for ENERGY STAR® certified equipment, and there is currently a federal tax credit of 30 % of project cost (up to $600) under the Inflation Reduction Act. We handle all paperwork and deduct confirmed incentives up-front so you see the savings immediately.
How long will installation take and will I be without water during the process?
Most projects are completed in one business day. We start by shutting off water and power/gas to the old heater, drain and remove the tank, and prepare new vent or electrical runs. Your water supply is usually off for 2–3 hours, and total hot-water downtime is 4–6 hours. If gas-line upsizing or electrical sub-panel work is required, we schedule those tasks first to minimize disruption. Our technicians bring temporary water heaters for households that cannot be without hot water (e.g., childcare facilities). Before leaving, we test all gas and water connections, set temperature limits, and show you how to use the digital controller.
What kind of regular maintenance does a tankless unit need and can you provide it?
A tankless heater should be flushed with a mild descaling solution every 12–24 months to remove mineral buildup and keep the heat exchanger efficient—more often if Reliance’s water hardness exceeds 12 grains per gallon. The air inlet screen and condensate trap (on condensing models) also need annual cleaning. Endless Supply Plumbing offers a low-cost service plan that includes a yearly flush, combustion analysis, software updates on Wi-Fi-enabled units, and a 15-point safety check. Routine maintenance keeps your warranty valid and typically extends equipment life well past two decades.
Will a tankless water heater work with my current gas or propane line and what are the electrical requirements?
Most modern gas tankless models need ¾-inch gas supply and may require up to 200 k BTU/h input—about 2–3 times that of a 40-gallon tank. If your existing line is undersized, we can upsize the run or install a secondary regulator at minimal added cost. Electric tankless units draw 80–120 amps and usually require three 40-amp double-pole breakers. During the site visit we measure line sizes, gas pressure, and panel capacity. If upgrades are needed, we provide an all-inclusive quote that covers licensed electrical or gas-fitters. Venting is through polypropylene or stainless steel concentric pipe, so no chimney is required, and horizontal side-wall termination is common in Reliance’s single-story homes.
