The company’s licensed technicians undergo ongoing manufacturer training, giving them a deep familiarity with the latest gas and electric models as well as smart-connected accessories.

Detailed Home Assessment

A comprehensive site evaluation is the cornerstone of every HEP installation. Technicians measure peak flow requirements by factoring faucet counts, shower fixtures, and simultaneous appliance usage. They also inspect gas pressure or electrical panel capacity to determine whether utility upgrades are necessary. The resulting recommendations are tailored; a three-bath Signal Mountain home with a whirlpool tub receives a different configuration than a downtown loft occupied by a single professional.

Local Code Knowledge And Permitting

Hamilton County and the surrounding municipalities apply National Fuel Gas Code and International Plumbing Code guidelines—yet each jurisdiction establishes unique amendments. HEP’s field supervisors submit permit applications, schedule in-progress inspections, and meet with code officials as required, sparing homeowners bureaucratic complexity while ensuring the new equipment satisfies every safety benchmark.

Coordination With Other Trades

Many Chattanooga remodels involve simultaneous electrical rewiring, HVAC replacements, or kitchen expansions. HEP coordinates timelines with electricians and general contractors, preventing schedule gaps and eliminating redundant drywall or flooring repairs.

Understanding How A Tankless Water Heater Works

Unlike a storage tank, which heats 40-plus gallons regardless of immediate demand, a tankless unit remains dormant until a fixture opens. At that moment, intelligent sensors trigger the burner or heating elements, warming water as it flows through a heat exchanger. Once the faucet closes, energy input halts.

Flow Activation

• Minimum flow rates range from 0.3 to 0.5 gallons per minute.
• Low-profile motion-activated bathroom faucets easily surpass this threshold.

Heat Exchanger And Modulating Burners

Modern gas models deploy stainless-steel or copper heat exchangers. A variable-speed fan introduces combustion air, while a modulating gas valve fine-tunes flame intensity. Electric models rely on multiple heating coils that energize individually to maintain set temperature with minimal power draw.

Digital Controls

Today's tankless units feature onboard microprocessors and Wi-Fi modules. Users can program vacation modes, monitor cumulative run time, and receive service alerts directly on a smartphone. HEP configures these settings during commissioning to reduce homeowner learning curves.

Comparing Gas And Electric Tankless Options

Chattanooga’s energy landscape includes affordable natural gas rates and a robust electrical grid supplied by hydroelectric generation. Both fuel sources can yield exceptional hot-water performance when paired with the right home.

Natural Gas & Propane Tankless Units

• Offer the highest flow capacities—ideal for households with three or more concurrent hot-water draws.
• Require stainless venting, pressure regulators, and adequate combustion air.
• Support outdoor mounting, freeing indoor real estate and simplifying condensate routing.

All-Electric Models

• Deliver whisper-quiet operation with zero combustion gases, allowing installation in interior closets.
• Eliminate the need for venting, a major advantage in condominiums and brick homes with limited chase space.
• Often necessitate 120- to 150-amp service panels for whole-home coverage, an upgrade HEP’s electricians integrate seamlessly.

Selecting The Right Size

HEP calculates required BTUs or kilowatts through a detailed formula that considers:

• Maximum simultaneous fixtures (showers, dishwashers, washing machines)
• Desired outlet temperature (commonly 120 °F)
• Average winter groundwater temperature (about 52 °F in Chattanooga)

A common Chattanooga configuration might target 7.5 gallons per minute at a 68-degree rise, guiding the choice toward a 180,000-BTU gas unit or a 36-kW electric unit.

Pre-Installation Plumbing Evaluation

A tankless water heater magnifies any deficiencies present in existing supply lines or fixtures. To safeguard performance, HEP conducts a plumbing audit before committing to installation.

Water Hardness And Its Impact

The Tennessee River Basin can introduce mineral hardness measuring between 5 and 10 grains per gallon. Scale deposits constrict the heat exchanger’s narrow water channels, undermining efficiency. If hardness exceeds six grains, HEP recommends integrating a whole-home softener or installing an isolation valve kit for routine descaling.

Venting Pathways In Older Chattanooga Homes

Historic neighborhoods like St. Elmo feature thick masonry walls that complicate vent routing. HEP’s technicians employ core-drilling equipment or reroute vent lines through attics to meet manufacturer clearance guidelines without compromising the building’s architectural integrity.

Load Calculations For Multiple Fixtures

Large family residences often juggle showers, laundry, and dishwashing in quick succession. HEP maps fixture usage patterns into a graphical load profile to verify the selected tankless model can sustain peak demand without temperature fluctuations.
