Remarkable 90% AFUE Efficiency
The Q90 dramatically reduces fuel consumption and pays for itself with substantial annual fuel savings. Its efficiency is increased beyond 90% when used in low temperature systems, such as radiant systems.
Revolutionary Cast Aluminum Heat Exchanger
Transfers heat three times faster with greater thermal conductivity than conventional cast iron. It produces enormous gains in heat-up speed and operating efficiency. Also, the packaged boiler weighs only 220 pounds for easier installation.
Safe, Economical CPVC and PVC Vent Pipe
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.
Sealed Combustion, Direct-Vent System
Unlike conventional residential atmospheric and induced draft boilers, the Q90 draws fresh air from outdoors for combustion, instead of air from inside the home. Therefore it does not compete with building occupants for its air supply. With this design the Q90 runs quieter than a traditional boiler.
Simplified Controls
The Quantum 90’s simple design is engineered to maximize reliability. The Q90 incorporates an integrated boiler control for operation, safety and diagnostics. A High Temperature Limit Control is included for additional safety. Ignition is provided by a hot surface igniter and a single stage gas valve. A single pressure switch ensures air intake and exhaust vents are clear. All components are easily accessible through the removable door.
Environmentally Friendly
The Q90's direct-vent system, premix gas burner and low flame temperature substantially reduce CO and NOx emissions (acid rain and smog components).
