FAQs
What are the main advantages of switching to a tankless water heater in Sewanee?
Tankless units heat water on demand, so you never run out of hot water and you eliminate standby heat loss from a storage tank. Most customers see energy-bill savings of 20-40 %, and the compact wall-mounted design frees up valuable floor space. Because high-efficiency models last 20+ years with proper care—almost double the life of a traditional tank—the long-term return on investment is excellent.
How do I determine the correct size (flow rate) for my new tankless water heater?
Sizing is based on the total gallons per minute (GPM) of hot water your household may need at one time. We add up the demand of simultaneous fixtures—showers, washing machine, dishwasher, etc.—and factor in Sewanee’s incoming winter water temperature (roughly 50 °F) to ensure the unit can raise water to 120 °F or higher. During a free in-home consultation, our licensed plumber measures these variables and recommends a model that delivers the right flow rate without oversizing, which keeps the upfront cost and energy use in check.
Is a tankless water heater reliable during Sewanee’s colder months?
Yes. Modern tankless systems include advanced modulating burners and freeze-protection circuitry. When installed and vented correctly, they maintain set temperature even during sub-freezing snaps common on the Plateau. Our technicians also insulate exterior piping and, if needed, install a recirculation loop so hot water arrives quickly to distant fixtures—eliminating the “cold-water sandwich” effect.
What does the installation process involve and how long will it take?
1) Site visit & load calculation. 2) Permit filing with Franklin County if gas or venting changes are required. 3) On installation day we shut off utilities, remove the old tank, mount the new unit, upsize gas or install a dedicated 240-V circuit (if electric), run stainless-steel venting, and flush the lines. Most residential jobs are completed in 6-8 hours, so you have hot water again by dinner. We haul away and recycle the old tank at no extra charge.
Will I need to upgrade my gas line or electrical service?
Gas tankless heaters often require a ¾-in. gas line and up to 200,000 BTU/hr capacity; many older homes in Sewanee have ½-in. lines that must be upsized. Electric models may need a 120-amp dedicated breaker, which can exceed the capacity of older 100-amp panels. During our assessment we measure your existing supply, discuss the least-invasive upgrade options, and provide firm pricing before any work begins.
What ongoing maintenance is required, and do you offer service plans?
To keep the heat exchanger free of mineral scale from Sewanee’s moderately hard water, manufacturers recommend a professional descaling once a year (every 6 months if you have a high-usage household). We offer an affordable annual maintenance plan that includes flushing with food-grade vinegar, inspecting the burner, checking vent integrity, updating firmware, and verifying combustion settings. Regular service preserves the warranty and ensures top efficiency for decades.
