Navien Gas Boilers

Combi boilers can produce both heat, and domestic hot water on demand. We feature Navien natural gas boilers and combi boilers. Key features include:

  •   High Capacity: Systems are available that can supply both heat and domestic hot water for larger homes — enough space heating for a whole house, plus hot water to run up to 3 showers and a dishwasher all at the same time.
  •   Stainless steel heat exchangers: Navien’s advanced stainless steel heat exchanger design resists corrosion better than copper for longer life.
  •   Low noise levels: Installations in or near media rooms, recreation rooms or any living areas of the house are possible with quiet running Navien boilers.
  •   Multiple venting options: Low exhaust gas temperatures allow use of PVC, CPVC, polypropylene (rigid and flexible) and stainless steel venting reducing installation time and costs. Systems can use 2" venting for up to 60', or up to 150' with 3" venting.
  •   High turndown ratios up to 15:1: The sophisticated gas flow control system provides a high turndown ratio, reducing energy waste and excessive combi-boiler cycling and enhances temperature control for DHW.
  •   NaviLink™ WiFi Control: The NaviLink™ Wi-Fi control system provides access to Navien condensing combi-boilers from anywhere in the world with your Apple or Android mobile device.

Replacement Boiler Installations

Hot water and steam boilers are a traditional winter heating source. Heated water is produced typically with a natural gas boiler and distributed to radiators, hot water baseboards, or in recent years, in floor radiant heat or zoned air handlers. Boilers make zoning easy, so that different areas of your home can be separately controlled with their own thermostat.

If you are considering replacing an existing boiler, we can help. We feature Burnham water and steam boilers that are terrific as replacement systems. Burnham Boilers are American made with caste iron heat exchangers and traditional chimney venting, perfect for many applications. We will perform a careful analysis of your current system, calculate a heat loss to determine the proper sizing, and suggest a proper efficient, modern Burnham replacement boiler system.
