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 Enhanced Series 2 (ES2) line of hot water boilers blends a reliable design with Burnham's cutting edge IQ Control System. ES2 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 ES25BNI-T is an excellent replacement for older natural draft boilers or the perfect addition for new construction.
Intelligent Hydronic Control
All ES2 boilers have Burnham's IQ Control System. The IQ system consists of two primary components: an IQ Option Panel and an Intelligent Hydronic Control. The Intelligent Hydronic Control is the centerpiece of Burnham's IQ Control System. 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 IQ Option Cards for outdoor reset, an auxiliary high limit, and low water cutoff. Options card are plug-and-play, which means customizing your ES25BNI-T is easier than ever.
Compact Venting Technology
All ES2 boilers contain a draft diverter. Internalizing this component means that the ES25BNI-T has a lower profile, providing you with more installation flexibility. The ES2 line also includes stainless steel flue baffles and a vent damper to provide ideal combustion conditions.
Cast-iron construction of the boiler sections contribute to the incredible longevity of ES2 models. The heat exchanger is also made of cast iron, which allows it to accept lower return water temperatures. By using a lower system temperature when possible, you will save energy and prevent short-cycling.
