Tankless Water Heater Installation & Service

Endless Hot Water. Maximum Efficiency.

If you’re tired of running out of hot water—or wasting money on a tank that heats water 24/7—switching to a tankless water heater might be the perfect upgrade. Mallard Plumbing installs and services high-efficiency tankless systems that deliver on-demand comfort and long-term savings.


We proudly serve homeowners in Bucks and Montgomery Counties with expert recommendations, seamless installs, and maintenance plans that protect your investment.

Why Go Tankless?

Homeowners love tankless systems for their comfort, efficiency, and space-saving design. Benefits include:

  • Endless hot water for showers, laundry, and dishwashing—without waiting
  • Energy efficiency: only heats water when you need it, lowering utility bills
  • Compact design saves space—ideal for tight utility rooms or wall-mounted installs
  • Longer lifespan than traditional tank systems (up to 20 years with proper maintenance)


Our Tankless Water Heater Services Include:

  • New Tankless Water Heater Installation – Sizing, setup, and code-compliant installation
  • System Conversions – Upgrade from a traditional tank to a modern tankless unit
  • Annual Maintenance & Flushing – Extend system life and maintain warranty compliance
  • Troubleshooting & Repairs – Diagnose ignition, scale, or flow issues fast
  • Water Quality Testing – Ensure your tankless system runs clean with the right filtration
