FAQs
How does a tankless water heater provide “endless” hot water?
Unlike storage tanks that heat and re-heat a fixed volume of water, a tankless (on-demand) unit uses powerful burners or electric elements to heat water instantly as it flows through a heat exchanger. As long as the unit’s flow-rate capacity is not exceeded and fuel or electricity is available, it keeps producing hot water—so you never run out during long showers or back-to-back loads of laundry.
What size tankless unit do I need for my home in Reliance?
Sizing is based on two factors: (1) the total gallons-per-minute (GPM) your household uses at peak demand—e.g., running two showers and a dishwasher at once—and (2) the temperature rise required, which in Reliance is typically 70-75 °F because our incoming groundwater averages 50-55 °F. A typical 2-bath home needs 6–8 GPM, while larger homes may require 9–11 GPM or multiple units in parallel. Our technician will perform a free flow-rate/temperature-rise calculation to recommend the right model.
How long does installation take, and will my existing plumbing or gas lines need major changes?
Most residential installations are completed in 4–8 hours. The tankless unit mounts on a wall, freeing up floor space. We usually repurpose your existing hot- and cold-water lines, but gas models may require a larger gas supply line and stainless-steel venting to meet code. Electric models may need a dedicated high-amp breaker. We’ll inspect your home in advance, provide a fixed quote, and handle all permits so there are no surprises.
Are tankless water heaters energy-efficient, and will they lower my utility bills?
Yes. Because they heat water only when you open a tap, tankless units eliminate the standby losses of keeping 40–50 gallons hot 24/7. ENERGY STAR® gas models are up to 96 % efficient and can cut water-heating costs by 30–40 %. Many units qualify for federal tax credits and local utility rebates, further improving payback. Savings vary with usage patterns: the more hot water your family uses at staggered times, the greater the benefit.
What maintenance is required for a tankless system in southeastern Tennessee?
The heat exchanger should be flushed with a vinegar or descaling solution once a year to remove mineral buildup common in our moderately hard water. We inspect and clean the combustion chamber, check the vent, and update firmware if applicable. Reliance Plumbing offers an affordable annual service plan that keeps your warranty intact and ensures peak efficiency.
Is a tankless water heater compatible with well water or hard water in Reliance?
Absolutely. Tankless units work with municipal or well supplies, but hard water (over 7 grains per gallon) can scale the heat exchanger faster. We recommend installing a sediment filter and either a scale-inhibitor cartridge or a whole-house softener. These low-cost add-ons protect the heater, extend its life, and maintain energy efficiency.
