Running out of hot water is one of the most frustrating household problems. If your old storage tank can’t keep up with daily demand, a tankless water heater may be the solution. Instead of storing and reheating gallons of water, tankless units heat water only when you need delivering continuous hot water, lower energy costs, and more space in your home. At Penn Mechanical Company, we provide expert installation, replacement, repair, and maintenance for tankless water heaters, ensuring your system is sized correctly and performs reliably for years to come.
Choose tankless if you want:
Precision Sizing & Installation
We calculate flow rate and temperature rise for your fixtures, right-size the unit, and install to manufacturer specs and local code. Gas lines, venting, condensate, and electrical are all handled by our licensed pros—no shortcuts.
Replacement & Conversions
Upgrading from a storage tank? We’ll convert gas/venting as needed, remove the old unit, and bring your new tankless system online with a clean, safe startup.
Repairs & Tune-Ups
From ignition faults to flow sensors and venting issues, our technicians carry the right parts to diagnose and fix problems quickly.
Maintenance & Descaling
Hard water happens. Annual (or hardness-based) service keeps heat exchangers clean and efficient, protects your warranty, and extends system life. We flush the unit, clean filters, inspect the burner & venting, and verify combustion.
Recirculation & Almost-Instant Hot Water
Want faster hot water at far taps? We integrate compatible recirculation controls/pumps so you get comfort without the wait.
They heat water instantly, but water still has to travel through the piping. Add a recirculation feature for near-instant delivery at fixtures.
Plan on annual service, adjusted for local water hardness and usage. This helps prevent scale buildup and protects performance and warranties.

Both exist. Gas models are common for whole-home use; electric can work for smaller loads or point-of-use. We’ll recommend based on infrastructure and goals.
