Why Tankless Water Heaters Make Sense for Lehigh Valley Homes
Tank water heaters store 40 to 80 gallons of water at a set temperature around the clock, consuming energy to reheat it repeatedly whether or not hot water is being used. The U.S. Department of Energy notes that water heating accounts for approximately 18 percent of residential energy use, and standby heat loss from storage tanks is a primary contributor. For Allentown and Quakertown homeowners looking to reduce utility bills and eliminate the recurring frustration of running out of hot water mid-shower, a correctly sized ENERGY STAR certified tankless unit addresses both problems in a single installation.
The Lehigh Valley’s older housing stock presents an additional practical argument for tankless conversion. Homes built in the 1950s through 1980s with small utility closets or finished basements often lack the floor space for a modern large-capacity storage tank. A wall-mounted tankless unit occupying a fraction of the footprint resolves the space constraint while delivering continuous hot water on demand.
Tankless vs. Storage Tank Water Heater Comparison
| Feature | Tankless Water Heater | Storage Tank Water Heater |
| Hot Water Supply | Continuous on demand | Limited by tank capacity |
| Energy Use | Heats only when needed | Standby heat loss 24/7 |
| Service Life | 20+ years with annual maintenance | 8-12 years average |
| Space Required | Wall-mounted, minimal footprint | Floor space for 40-80 gal tank |
| Water Supply Risk | No tank to corrode or burst | Tank failure can flood home |
| Hard Water Sensitivity | Scale on heat exchanger (annual flush) | Scale on element and tank floor |
| Installation Complexity | Gas/venting/electrical assessment required | Straightforward like-for-like swap |
Our Tankless Water Heater Installation Process
- Pre-Installation Assessment: We evaluate your home’s existing gas supply, venting path, and household peak hot water demand. This determines unit sizing, any required gas line or venting modifications, and the total project scope.
- Permit Application: Mastery Plumbing pulls all required plumbing and mechanical permits through the applicable local building authority. Homeowners do not need to manage any paperwork.
- Installation: We remove and dispose of the existing water heater, install the tankless unit, complete all gas, venting, and water connections to code, and install any required pressure relief valve, isolation valves, and flush kit access ports.
- Commissioning: We start the unit, verify ignition function, confirm set temperature and output temperature at fixtures, and check all connections for leaks.
- Inspection Coordination: We coordinate the required post-installation inspection with the local building authority and confirm approved status before closing the permit.
- Homeowner Walkthrough: We demonstrate operation, review the annual maintenance schedule, and confirm warranty registration before departure.

Mastery Plumbing diagnoses and repairs all major brands of tankless water heaters throughout the Lehigh Valley. Common repair scenarios include: error code diagnostics; heat exchanger descaling on units with mineral scale buildup from hard water; flow sensor replacement; ignition assembly service; venting blockage clearing; and gas valve or pressure regulator replacement. For water heater repair calls, we carry common replacement parts for the brands most frequently installed in the area. If the unit is beyond economical repair, we provide a water heater installation estimate on the same visit.
Homes with hard water or elevated iron content in the area’s well water supply benefit from water softener installation upstream of the tankless unit to reduce scale accumulation on the heat exchanger.
