FAQs
How does a tankless water heater work and what advantages does it offer over traditional tank models?
A tankless water heater (also called an on-demand or instantaneous heater) uses high-efficiency gas burners or electric elements to heat water only when a hot-water tap is opened. Because there is no storage tank that must keep 40–50 gallons hot 24/7, standby heat losses are eliminated. The result is a virtually endless supply of hot water, a unit that takes up far less space, and energy savings that can reach 25–40 % compared with a standard tank heater. In addition, most quality tankless systems last 20+ years—roughly twice the lifespan of a conventional tank—reducing long-term replacement costs.
Is a tankless water heater the right choice for my home in Hixson?
Most single-family homes and many small businesses in Hixson are excellent candidates for a tankless system. Key factors to confirm are: (1) adequate fuel supply—natural gas is ideal, but propane or electric units can be used with proper service upgrades; (2) sufficient incoming water flow—our technicians will calculate your peak demand in gallons per minute (GPM); and (3) proper venting location—gas models require stainless-steel or PVC venting to the exterior. During a free in-home assessment, we measure your current hot-water usage, check gas line size and electrical capacity, and identify the best mounting and venting points to determine if tankless is the optimal solution.
What size and flow rate tankless unit will I need?
Tankless heaters are sized by maximum flow rate in GPM at a specified temperature rise (difference between incoming cold water and desired hot water). In Hixson, winter groundwater can be as low as 50 °F, so achieving a 120 °F output requires a 70 °F rise. As a rule of thumb: • 1 shower = 2.0–2.5 GPM, • kitchen sink = 1.5 GPM, • washing machine = 2.0 GPM. If you may run two showers and a dishwasher simultaneously, you need roughly 6–7 GPM at a 70 °F rise. Our team performs a detailed load calculation to recommend the correct BTU or kW rating (typically 180,000–199,000 BTU for gas units or 24–36 kW for electric) so you never run out of hot water.
How long does installation take, and what should I expect during the process?
A standard tankless retrofit in Hixson generally takes one full working day. Steps include: (1) draining and removing your old tank; (2) upgrading gas line diameter or installing a dedicated 240-V circuit if electric; (3) hanging the compact tankless unit on an interior or exterior wall; (4) routing intake/exhaust venting through the roof or sidewall; (5) connecting hot- and cold-water lines with isolation valves and a condensate drain; and (6) testing, flushing, and programming the unit’s temperature controls. Our licensed plumbers protect floors, haul away the old tank, and pull all required Hamilton County permits so the job is code-compliant and mess-free.
What maintenance does a tankless water heater require?
Tankless systems need less routine attention than storage tanks but still benefit from annual service: • Descale and flush the heat exchanger with a vinegar solution to remove mineral buildup (especially important with Hixson’s moderately hard water). • Clean the inlet water filter and combustion air screen. • Inspect the burner flames, igniter, and venting for proper operation and safety. • Update firmware on smart models. Our Performance Plumbing Care Plan includes an annual tune-up, descaling, and priority scheduling, helping maintain efficiency, preventing error codes, and keeping most manufacturers’ warranties in force.
What energy savings and rebates are available for tankless water heaters in Hixson?
Because tankless units only heat water when needed, ENERGY STAR®-qualified models can cut water-heating bills by 25–40 %. The federal Energy Efficient Home Improvement Credit allows up to 30 % of the installed cost (capped at $600) for qualifying gas tankless heaters through 2032. Tennessee Valley Authority (TVA) periodically offers additional incentives or low-interest financing for high-efficiency natural-gas upgrades. We handle all paperwork, provide the AHRI certification, and guide you through rebate submission so you receive every available dollar back after your installation.
