HEP’s Comprehensive Plumbing Approach
Initial Assessment and Sizing
Proper sizing is the foundation of a successful tankless installation. HEP plumbers perform a detailed load calculation that accounts for:
- Maximum number of simultaneous fixtures (showers, sinks, appliances)
- Incoming ground water temperature specific to Decherd’s climate profile
- Desired output temperature and flow rate
- Fuel type availability (natural gas, propane, or electric service capacity)
Sizing prevents under-powered units from struggling during peak demand while avoiding overspending on unnecessarily large equipment. HEP uses this data to recommend the optimal model for each residence or commercial property.
Gas Line and Electrical Considerations
Gas-fired units require sufficient BTU input and correct pipe sizing. HEP technicians verify existing gas lines or design new routing to accommodate the heater’s requirements. For electric models, panel capacity is evaluated to ensure circuit breakers and wiring gauge meet manufacturer specifications. Any upgrades are completed as part of the project, streamlining the entire process.
Venting and Condensation Management
High-efficiency condensing tankless units release cooler exhaust but produce condensation that must be safely drained away. HEP selects vent materials rated for acidic condensate, installs horizontal or vertical venting per code, and integrates neutralizers where necessary to protect drain lines and septic systems.
Post-Installation Testing and Calibration
Precision doesn’t stop once the water is flowing. HEP plumbers:
- Measure gas pressure or voltage draw under load
- Verify proper ignition and burner modulation
- Check for leaks at every connection point
- Calibrate temperature settings to customer preference
- Document results for warranty validation and future service records
These diligent checks confirm that each new tankless system in Decherd performs exactly as designed.
