Tankless water heater installation in Dillsburg, PA
Endless hot water, half the floor space, and a unit that should still be running after the kids leave for college. Premier Dillsburg Plumber sizes, vents, gases, and pressure-tests every tankless install ourselves - no subcontracted labor, no shortcut on the gas-load calc.
What changes when you switch to tankless
Hot water that doesn't run out
A 199K BTU condensing tankless delivers 8 to 11 GPM of hot water - that is two showers and the dishwasher running at the same time without anyone yelling. The 50-gallon tank you replaced gave up after 20 minutes.
Wall-mounted, not floor-eating
Tankless units measure roughly 18" wide x 28" tall x 11" deep. The closet that used to hold a 60-inch tank can now hold a water softener and a utility sink with room to spare.
Twenty-year service life
Tank-style heaters average 9 to 11 years in Central PA hard water. A descaled tankless typically goes 20+. The heat exchanger is the only major service item; we replace gas valves, igniters, and flow sensors as routine wear.
What we install (and don't)
We install condensing tankless models exclusively. They vent in PVC or stainless and capture latent heat from the exhaust, hitting 95% thermal efficiency. Non-condensing units are cheaper but vent in expensive Category III stainless and lose 15% efficiency to the flue.
- Navien NPE-A2 / NPE-S2 - integrated recirculation pump for fast hot water at distant fixtures.
- Rinnai RU and Sensei - reliable, easy parts, broadest installer network.
- Rheem RTGH and Noritz NRC - solid value picks for 2 to 3 bath homes.
If you've got a propane home (common in northern Dillsburg / Wellsville), all three brands have LP variants - we'll match the orifice and gas pressure to your tank or wall regulator.
What a real tankless install includes
- Gas-line load calculation. A 199K BTU tankless adds a major draw to your gas system. We measure existing pipe diameter, count BTU loads, and upsize to 3/4" or 1" black iron or CSST as needed.
- Vent path engineering. Concentric or two-pipe vent in 3" PVC or 4" stainless. Termination has to clear windows, soffits, and grade per manufacturer spec. We never improvise this.
- Condensate routing. Condensing tankless produces acidic condensate that has to be neutralized before going to a drain. We install a neutralizer cartridge and tee into a drain or pump where allowed.
- Isolation valves. Service kits with full-port isolation valves so the heat exchanger can be flushed in 25 minutes by you (or by us, on a maintenance plan).
- Recirc loop, if present. Crossover valves, dedicated return lines, or built-in recirculation - sized so you don't burn 6 KWh a day on a pump that runs all night.
- Permit and inspection. Pulled with the borough or township. Pressure test on the gas, leak test on the water, and a final on the venting and combustion air.
