Dunkirk Q90-100 Condensing Gas Boiler

Dunkirk Q90-100 Condensing Gas Boiler

50-75-100 MBH

When considering a condensing boiler for your home, ECR International provides you with a choice. We offer a fixed capacity boiler rated at 90% AFUE. The 95M is a modulating boiler with an AFUE of 95%. The modulation feature of the 95M allows the boiler to change its heat output relative to actual current load requirements. Modulating boiler applications are best for larger homes with many or small zones. In these applications the boiler will modulate to a lower output versus cycling on and off when the smaller zones call for heat, reducing temperature swings and maximizing comfort.

The Q90-100 offers a remarkable 90% AFUE efficiency rating, dramatically reducing fuel consumption and paying for itself in substantial fuel savings. The Q90-100 utilizes a cast aluminum heat exchanger, offering greater thermal conductivity which transfers heat three times faster than conventional cast iron and produces enormous gains in heat-up speed and operating efficiency. The Q90-100 features integrated boiler control with high limit for operation, safety and diagnostics. Ignition is provided by a hot surface igniter and single stage gas valve. Air flow proving switches ensure air intake and exhaust vents are clear. All components are easily accessible for ease of installation and maintenance. Unlike conventional atmospheric boilers, the Q90-100 has sealed combustion, direct-vent forced draft design to draw fresh air from outdoors for combustion, instead of from inside the home. Cooled flue gas can be safely vented through inexpensive, readily available and easy to install PVC, after 5'' of CPVC provided with the unit. The air intake also utilizes PVC pipe.
