Tankless Water Heater Installation in Mt Lebanon, PA

What Is a Tankless Water Heater?

Unlike traditional storage-tank models that keep 40–80 gallons of water heated at all times, tankless units heat water only when a faucet, shower, or appliance calls for it. This on-demand design works through a powerful heat exchanger—powered by natural gas or electricity—which rapidly raises water temperature to your set point. The result is an uninterrupted hot water stream, ideal for busy families and commercial settings alike.

Benefits of Going Tankless

• Energy Savings & Lower Utility Bills
• Up to 30% reduction in water-heating energy use
• No standby heat losses from stored hot water
• Endless Hot Water Supply: Simultaneous showers, laundry, and dishwashing without cold spots
• Space Efficiency: Wall-mounted footprint frees up basement or utility closet space
• Longer Service Life: Typical lifespan of 20+ years vs. 10–15 years for tanks
• Reduced Risk of Leaks & Water Damage: Absence of large storage tank minimizes rupture concerns

Sizing Your Tankless System

Selecting the right tankless unit in Mt Lebanon hinges on two key factors:

Peak Flow Rate (Gallons Per Minute, GPM)

• Bathroom sink: 0.5–1.0 GPM
• Shower: 1.5–2.5 GPM
• Dishwasher: 1.0–1.5 GPM
• Clothes washer: 2.0–2.5 GPM

Required Temperature Rise

• Incoming groundwater can range from 45°F (winter) to 65°F (summer).
• To reach a typical 120°F outlet, calculate ΔT (e.g., 60°F rise in winter).

A household with two bathrooms running simultaneously may need a 5.0–6.5 GPM unit, whereas larger homes could require cascaded or dual-unit setups for 10+ GPM capacity. Our flow-rate guide and in-home assessment ensure you invest in a system sized precisely for your usage patterns.
