Q90-200 Natural Gas-fired Boiler

Remarkable 90% AFUE Efficiency

The Q90-200 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 “Mono Block” Heat Exchanger

This one-piece heat exchanger design eliminates leaks that can occur due to section interface with sectional heat exchangers. The greater thermal conductivity of cast aluminum transfers heat three times faster than conventional cast iron, producing enormous gains in heat-up speed and operating efficiency. Also, the packaged boiler weighs only 220 pounds for easier installation.

Simplified Controls

The Quantum 90-200’s control design is engineered to maximize reliability. The Q90-200 incorporates an integrated boiler control with high limit and low water cut-off for operation, safety and diagnostics. Ignition is provided by a hot surface igniter and a single stage gas valve. Dual switches ensure air intake and exhaust vents are clear. All components are easily accessible through the removable door.

Sealed Combustion, Direct-Vent System

Unlike conventional atmospheric boilers, the Q90-200 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 Q90-200 runs quieter and more efficiently than a traditional boiler.

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.

Environmentally Friendly

The Q90-200's direct-vent system, premix gas burner and low flame temperature reduce CO and NOx emissions (acid rain and smog components) by more than 30% and 50% respectively.
