Tankless Water Heater

Tankless Water Heater Services in Berks County,Pennsylvania. Endless comfort. Smarter efficiency. Installed the right way.

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.

Why Go Tankless? (Real-World Benefits)

  • Hot water on demand: Heats water as you use it, so you’re not limited by tank capacity.

  • Lower energy use: For typical households, tankless units can be 24–34% more efficient than standard tanks; even heavy-use homes can see 8–14% efficiency gains. That’s money back in your pocket, month after month. 

  • Compact footprint: Wall-mounted units free up closet/basement space.

  • Long service life: Fewer standby losses and replaceable components help systems last longer.

  • Smart add-ons: Recirculation features can deliver near-instant hot water at distant fixtures when properly configured.

Your Trusted Installation & Replacement Experts

Is a Tankless Water Heater Right for Your Home?

Choose tankless if you want:

  • Back-to-back showers or simultaneous uses (laundry + dishes + bath) without who used all the hot water?

     

  • Efficient performance for households that don’t need a huge tank, reheating 24/7.

     

  • Space savings in mechanical rooms, closets, or small basements.

     

  • Flexible control with optional recirculation for fast-at-the-tap hot water. (Note: tankless doesn’t mean instant at a distant tap; water still has to travel through the pipes unless you add recirculation.) 

Our Tankless Services

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.

How We Size Your Tankless (Simple, No Jargon)

  1. List your biggest simultaneous uses (e.g., shower + dishwasher).

  2. Add up flow rates (gallons per minute) for those fixtures.

  3. Factor in temperature rise (how much we must heat your incoming water).

  4. Match a unit that delivers that GPM at your needed rise—with headroom for winter.
    We’ll walk you through the numbers so you know exactly what you’re getting and why.
