Navien Residential Combi-Boilers

Navien is considered a global leader in tankless water heaters and combi-boilers. If you are looking for not just a new water heater but also a futuristic heating system for your home, then look no further than Navien.

What can a Navien system do?

  • Unlimited hot water: The expertly engineered systems can provide endless hot water on demand. Without a tank, a Navien tankless water heater pushes water through an integrated heating system, which is efficient enough to reach the set temperature in an instant. As long as your home has running water, you will have hot water thanks to a Navien system.
  • Whole-home heating: Navien NCB-H and NFC-H Series systems can provide whole-home heating solutions, not just hot water from various water outlets. It works by running hot water through pipes installed throughout the walls, floors, and ceilings of your home, much like a series of radiators hidden out of sight. The Navien can create endless hot water, too, so you never have to worry about the system running out and making your home cold.

Navien tankless water heater systems are famous for their compact design, too. If you have a water heater, then you should have space for a Navien model—and then some.

    Loran Scharf came by to service our heating system for the winter and drain the hot water tank. Loran is very professional and does excellent work. He's been the person to do our service since we moved into our home in 2019 and we always ask for him. Hope Bel- O appreciates that they have a great representative of their company!

  • "What a great value for the peace of mind!"
    We recently had a technician out to do a maintenance and cleaning of our furnace.The experience was great as he took his time to clean and inspect the system and to go over any findings/recommendations he had for us. We took advantage of the great maintenance plan they offer and look forward to having them back out in the spring to maintenance the AC. What a great value for the peace of mind!
