Burnham is devoted to pushing the limits of heating technology and efficiency. Their ingenuity is responsible for some of the most efficient boilers on the market today. The Series 3 line of hot water boilers blends a reliable design with Burnham’s cutting edge IQ Control System. Series 3 boilers save energy by doubling down on heat retention with an insulated jacket and plates. Possessing industry standard tapping locations, simplified venting, and exceptional efficiency, the 305BNI-T is an excellent replacement for older natural draft boilers or the perfect addition for new construction.
- Intelligent Hydronic Control
- Burnham’s IQ system consists of two primary components: an IQ Option Panel and an Intelligent Hydronic Control. The IHC supports two setpoints, controls ignition, provides fan and circulator relays, and acts as an aquastat.
- IQ Option Panel
- The IQ Option Panel provides a standardized and simplified way to add functionality to your boiler. It supports Burnham’s plug-and-play IQ Option Cards for outdoor reset, an auxiliary high limit, and low water cutoff.
- Compact Venting Technology
- All Series 3 boilers contain a draft diverter. By internalizing this component, the profile of the boiler and the space required for installation is reduced. The 305BNI-T also includes a vent damper to provide ideal combustion conditions.
- Durable Construction
- Cast-iron construction of the boiler sections contribute to the incredible longevity of Series 3 models. The heat exchanger is also made of cast iron, which allows it to accept lower return water temperatures.
