FAQs
What advantages does a tankless water heater offer compared to a conventional storage-tank unit?
Tankless water heaters heat water only when you open a tap, eliminating standby heat loss from a stored tank. This on-demand operation can cut water-heating energy use by 25–40 %, provide an endless supply of hot water, free up floor space, and typically extend equipment life to 20+ years (about twice that of a tank). Many Dunlap homeowners also appreciate the lower risk of tank leaks and the option to mount the unit on a wall, which is helpful in smaller utility rooms or crawlspaces common in our area.
How do I determine the right size (capacity) tankless unit for my Dunlap home?
Sizing is based on two factors: (1) the peak flow rate your household will need (measured in gallons per minute, or GPM) and (2) the temperature rise required—how much the unit must heat incoming water to reach your desired outlet temperature. We start by listing the fixtures you might run simultaneously (e.g., one shower at 2.0 GPM + dishwasher at 1.5 GPM = 3.5 GPM). Groundwater in Dunlap averages 55–60 °F. To deliver 120 °F hot water, the heater must raise the temperature ~60 °F. A reputable installer will perform this calculation during an in-home visit to recommend a model with enough BTU output to meet that demand, usually 6–9 GPM for a typical three-bedroom home.
What does the installation process involve and how long will it take?
Most residential installations are completed in one day. We begin by shutting off utilities, draining and removing the old tank, and preparing a wall location for the new unit. Because tankless heaters require higher BTU input, we may need to upsize the gas line (usually from ½" to ¾" or 1") or add a dedicated 240-V circuit for electric models. Proper stainless-steel or PVC venting is installed to meet both manufacturer specs and Sequatchie County building codes. After mounting the heater, we connect water, gas/electric, and condensate lines, flush the system, set temperature, and demonstrate operation. Permits and final inspections are coordinated with the city of Dunlap when required.
Will I need additional maintenance for a tankless system?
Maintenance is straightforward: (1) flush the heat exchanger with a vinegar solution once a year to remove mineral scale—especially important with Dunlap’s moderately hard water (7–10 grains per gallon); (2) clean the in-line sediment filter every six months; and (3) inspect the venting and condensate drain for obstructions. Annual service typically takes less than one hour and costs far less than dealing with tank corrosion or leaks in a storage-type heater.
Can a tankless water heater reduce my utility bills in Dunlap?
Yes. Because water is heated only when you need it, gas tankless models regularly achieve 0.82–0.95 Uniform Energy Factor (UEF), compared to 0.59–0.65 for standard gas tanks. For an average family using 60–70 gallons of hot water per day, this can translate to $80–$120 in annual natural-gas savings. Electric tankless units can save even more in homes where electricity rates are lower than propane or where time-of-use billing rewards lower baseline consumption.
Will a tankless unit work in older homes or with Dunlap’s water and climate conditions?
Absolutely. We routinely retrofit homes built in the 1960s and earlier. The key considerations are (1) verifying adequate gas line capacity or electrical service, (2) ensuring a location for proper venting, and (3) addressing any existing plumbing issues such as outdated galvanized piping. Dunlap’s mild winters keep incoming water temperatures relatively moderate, so tankless units operate efficiently year-round without the extreme temperature rises required in colder climates. If your house has very high mineral content in its well or municipal supply, adding a whole-house sediment filter or softener will maximize unit longevity.
