FAQs
What are the main advantages of installing a tankless water heater in Ten Mile?
Tankless units heat water on demand, so you never run out of hot water, and they eliminate standby heat loss common with storage tanks. They’re up to 35% more energy-efficient, can last 20+ years with proper care, free up floor space, and qualify for state and federal energy rebates that help offset the upfront cost.
How long does a typical tankless water heater installation take?
Most residential installations in Ten Mile are completed in one day. Our crew begins with a site inspection, disconnects and removes the old tank, installs any needed gas, electric, or venting upgrades, mounts the new unit, tests for leaks, and commissions the system. Larger homes or extensive utility upgrades can add a few extra hours, but same-day hot water is the norm.
What size tankless water heater do I need for my household?
Sizing is based on your peak simultaneous hot-water demand, measured in gallons per minute (GPM). A typical two-bath, three-bedroom home in Ten Mile usually needs a 7–9 GPM gas unit, while larger homes with multiple showers running at once may require 11 GPM or higher. Our technicians perform a free flow-rate calculation during the estimate to recommend the right model so you always have sufficient hot water.
Will a tankless system really lower my utility bills?
Yes. Because a tankless heater only fires when you open a tap, it avoids the 24/7 standby losses of storage tanks. The U.S. Department of Energy estimates savings of 8–34% for households that use 41 gallons or less of hot water daily, and 14% for heavier users. In Ten Mile, where natural gas rates average $1.10 per therm, that can translate to $80–$150 in annual savings, plus potential rebates from TVA and federal tax credits.
Do I need to upgrade my gas line or electrical service for a tankless unit?
Many gas tankless models require a ¾-inch gas supply line and up to 200,000 BTU input, higher than typical ½-inch lines serving a tank. Electric units often need a 200-amp service and dedicated breakers. During our on-site evaluation we measure line size, pressure, and panel capacity; if upgrades are needed, we’ll provide a fixed quote and coordinate all plumbing, electrical, and venting work so you have one hassle-free project.
How often does a tankless water heater need maintenance, and who should perform it?
Tankless heaters should be flushed annually in Ten Mile to remove mineral scale and preserve efficiency, especially if your water hardness exceeds 10 grains. The service includes descaling the heat exchanger, cleaning the inlet screen, inspecting the ignition system, and updating firmware on smart models. We offer affordable maintenance plans, but handy homeowners can perform the flush themselves with a pump kit and white vinegar if they’re comfortable following the manufacturer’s instructions.
