Dunkirk is one of the most established names in hydronic heating. Their reputation has been built over the years by ingenious design and perpetual innovation. Their Q90-100 series is a great way to bring condensing efficiency to your system. By redirecting gases that escape traditional boilers and reusing the heat contained within them, Q90-100 boilers make the most of your energy dollar. With a low profile and fan-aided direct venting, it is easy to find a space that suits the Q90-100. Supply and return connections are featured on the left and top of all Q90-100 models to provide flexibility for piping. The induced draft blower is adjustable, extending that flexibility to the vent pipe direction as well. The Q90-100 represents excellent efficiency in a package that fits most applications; it is a fantastic addition to any system.
Cast-Aluminum Heat Exchanger
Q90-100 boilers feature a cast-aluminum heat exchanger with a low pressure drop. Cast-aluminum is known for its amazing heat transfer capabilities, improving the speed and efficiency of heating in your system.
Premixing fuel and air leads to a cleaner burning flame and lower emissions of CO and NOx. Between these lowered emissions and the unit's tremendous energy efficiency, it is easy to feel good about installing a Q90-100.
The control for the Q90-100 features an energy saving operating mode. Economy Mode is set through a dial on the control. When active, it automatically manages the temperature and circulation of your system to find the perfect balance of efficiency and comfort.
