What our customers say
Why Harriman Homes Benefit from Tankless Water Heater Technology
Harriman’s mix of historic residences, new housing developments, and commercial spaces calls for a water-heating solution that can adapt to different plumbing footprints without wasting energy. A traditional storage-tank water heater constantly heats and reheats water, even when no one is using it. That “stand-by” heat loss translates into higher utility bills and unnecessary strain on the unit. Tankless water heater technology removes the storage tank from the equation, delivering hot water on demand. When a hot-water tap is opened, cold water travels through a heat exchanger, is warmed instantly, and is delivered at a consistent temperature.
HEP’s plumbing division specializes in tailoring this technology to Harriman properties. The company evaluates incoming water quality, gas line capacity or electrical supply, venting requirements, and the hot-water demands of each household. Because every installation is custom-fitted, homeowners avoid many of the pitfalls seen with one-size-fits-all solutions.
Key Advantages for Local Residents
- Space savings in basements, crawl spaces, and utility closets
- Potential energy-cost reductions of up to 40% compared with standard tanks
- Unlimited hot water for large families, hobby showers, or back-to-back laundry loads
- Longer equipment life expectancy, often exceeding 20 years
- Reduction of flood risk because there is no tank that can rupture
How HEP Tailors Tankless Water Heater Installations in Harriman
Every home presents a distinct set of challenges, from older galvanized pipes on Main Street to modern PEX systems in new subdivisions near the Clinch River. HEP’s licensed plumbers follow a detailed workflow to ensure correct sizing, proper venting, and code compliance.
Initial Home Evaluation
The process begins with an on-site evaluation. A HEP technician inspects the existing water heater location, measures the distance to fixtures, observes gas or electrical supply lines, and notes the insulation quality of the building envelope. These details influence both the fuel requirements and the selection of venting materials.
Calculating Flow Rate and Temperature Rise
Harriman sits within a region where incoming groundwater temperatures average 55–60°F. Delivering a comfortable 120°F shower requires a 60°+ rise at the outlet. HEP plumbers measure fixture flow rates—showerheads, dishwashers, washing machines—then add those demands to calculate gallons per minute (GPM). The result determines whether the property needs a single high-output unit or multiple cascading units.
Selecting Gas or Electric Models
Natural gas lines service most of Harriman, yet some neighborhoods rely on propane or enhanced electrical infrastructure. HEP’s product catalog includes both gas-fired and high-efficiency electric tankless models. The technician confirms:
- Gas line diameter and pressure
- Electrical panel amperage and breaker space
- Vent termination options and clearance from windows, doors, and property lines
Venting and Condensate Management
High-efficiency condensing tankless units extract additional heat from exhaust gases, producing condensate that must be neutralized. HEP installs condensate neutralizers and routes drain lines to nearby floor drains or condensate pumps. Proper vent slope and termination protect siding and roofing materials.
Permitting and Code Compliance
Harriman adheres to the Tennessee State Plumbing Code. HEP pulls the necessary permits, schedules inspections, and documents each project, ensuring homeowners remain fully compliant.
Energy Savings Specific to Harriman’s Climate
Although Harriman enjoys mild winters compared with regions farther north, space heating still consumes a sizable share of annual energy use. Water heating often ranks second. By switching to a tankless system, residents can significantly reduce natural gas or electricity consumption.
Reduced Stand-By Losses
Traditional tanks lose heat through their walls and through flue pipes. This loss intensifies during the cooler months when the temperature difference between the tank and ambient air is greatest. Tankless systems operate only when a tap opens, eliminating the round-the-clock heat loss.
Smart Modulation Technology
Modern tankless units employ sensors and computer boards that adjust burner output or electric heating elements in real time. When washing hands, the unit throttles down. When filling a soaking tub, it ramps up automatically. HEP configures this modulation during installation and tests it during the final walkthrough.
Cleaner Combustion and Fewer Emissions
Condensing gas units achieve up to 98% thermal efficiency, releasing cooler, less polluted exhaust. For Harriman homeowners focused on sustainability, the upgrade aligns with a smaller carbon footprint.
Addressing Harriman’s Water Quality Challenges
Water hardness varies across Roane County. Calcium and magnesium deposits can scale heat exchangers, reducing efficiency and shortening service life. HEP includes a water-quality analysis as part of each quote.
Whole-House Filtration and Softening Options
If hardness levels exceed manufacturer guidelines, HEP recommends:
- Anti-scale filter cartridges installed directly on the cold-water inlet
- Electronic scale reduction systems that use electromagnetic fields
- Salt-based softeners for extreme hardness scenarios
By addressing hardness up front, the company safeguards the stainless-steel or copper heat exchangers inside tankless units, preserving warranty coverage.
Integration with Existing Plumbing and Appliances
Switching to a tankless water heater is more than a simple swap; the plumbing network often requires optimization. HEP evaluates recirculation loops, pipe diameters, and fixture aerators to ensure optimum performance.
Hot-Water Recirculation
To shorten wait times at distant faucets, HEP can install:
- Dedicated return lines with demand-sensing pumps
- Comfort-control valves that use the existing cold-water line as a return
- Smart pumps that learn usage patterns and activate automatically
These systems keep hot water close to the tap without wasting energy.
Compatible Appliance Settings
Modern dishwashers and washing machines feature internal heaters, yet they still rely on incoming water temperature. HEP technicians adjust appliance settings to match the new tankless output, preventing over-heating and reducing cycle times.
Safety Measures Built Into Every Installation
Replacing a fuel-burning appliance demands strict safety protocols. HEP’s plumbers are trained to exceed code requirements.
Gas Line Integrity Testing
Before lighting the new burner, technicians perform:
- Pressure drop testing using calibrated gauges
- Soap-bubble leak checks on all fittings
- Verification of proper gas regulator sizing
Backdraft Prevention
Tankless units rely on sealed combustion that draws air from outdoors. Proper venting ensures no combustion gases can re-enter the living space. HEP also installs carbon-monoxide detectors adjacent to utility rooms for an added layer of protection.
Electrical Surge Protection
Electronic control boards inside tankless water heaters are sensitive to voltage spikes. Surge-protective devices guard against lightning strikes and utility fluctuations common during Harriman’s summer storms.
Long-Term Maintenance Plans
A tankless water heater’s life expectancy often exceeds two decades, provided the unit receives scheduled maintenance. HEP offers structured plans that fit local water conditions and usage patterns.
Annual Flush and Inspection
Mineral accumulation, although slower in soft water, can still form on heat-exchange surfaces. Flushing with food-grade vinegar or citrus-based solutions removes deposits. During this visit, the technician checks:
- Burner or element condition
- Vent piping integrity
- Flow sensor calibration
- Combustion air filters
Software Updates and Performance Logs
Many newer models feature Wi-Fi modules that track run-time hours and error codes. HEP technicians update firmware, review performance logs, and calibrate parameters for the upcoming season.
Component Replacement Schedule
- Inlet screens: inspected every 12 months
- Igniters: replaced every 5–10 years, depending on usage
- Expansion joints: evaluated with each flush for signs of fatigue
Environmental and Lifestyle Upsides for Harriman Residents
Beyond energy savings, tankless water heaters deliver lifestyle improvements that align with Harriman’s active culture.
Endless Hot Water for Recreational Living
Residents who return from boating on Watts Bar Lake, hiking in Frozen Head State Park, or working double shifts at industrial plants appreciate showers that never run cold. The technology keeps pace with demanding schedules and large families.
Freeing Up Valuable Storage Space
Small cottages near the river and modern townhomes alike benefit from the compact footprint of a wall-mounted unit. Extra square footage can be converted into pantry shelving, laundry folding stations, or hobby workbenches.
A Quieter Utility Room
Conventional tanks cycle on and off, producing audible burner roar or element hum. Tankless units remain silent until activated, and even then, sound levels rarely exceed a quiet conversation.
Common Myths Dispelled by On-Site Experience
While the benefits are clear, myths still circulate in community forums and neighborhood conversations. HEP addresses these misconceptions firsthand.
Myth 1: “Tankless Units Deliver Lukewarm Water”
Properly sized systems deliver consistent temperatures even when multiple fixtures open simultaneously. The key is accurate flow-rate calculations, a step HEP never overlooks.
Myth 2: “Water Takes Longer to Heat”
Distance to the fixture, not the heater type, governs wait time. With optional recirculation pumps, tankless systems can out-perform tank setups.
Myth 3: “Complicated Technology Means Constant Breakdowns”
Solid-state boards and durable heat exchangers often last longer than tank anodes or glass linings. Regular maintenance reduces unplanned downtime.

- Running oversize gas lines during initial install
- Installing modular manifolds that simplify fixture additions
Should an ADU be constructed behind a Harriman bungalow, the existing tankless infrastructure can often serve both structures with minimal adjustments.
Understanding Rebates and Energy Credits
At various times, state or federal programs offer tax credits for high-efficiency water heaters. HEP keeps current documentation on qualifying models and provides homeowners with serial numbers, efficiency certificates, and installation receipts required for filing purposes.
Potential Incentives
- Federal residential tax credits for ENERGY STAR certified models
- Utility company efficiency rebates based on unit Uniform Energy Factor (UEF)
- Local green-building points for home certifications
Securing these benefits can help offset a portion of the investment and accelerate the payback period.
Addressing Unique Commercial Needs in Harriman
Restaurants along Highway 70, bed-and-breakfasts overlooking the river, and barber shops on Roane Street all have specialized hot-water demands. HEP designs commercial-grade systems that incorporate:
- Redundant cascading tankless units for uninterrupted service
