Low NOx High Efficiency Condensing Unit Heaters The units exceed the requirements of current Building Regulations L2, with thermal efficiencies up to 109% to provide exceptional levels of seasonal efficiency. Also the extremely low NOx modulating pre-mix burner enables BREEAM points to be claimed (when applicable). These 4th generation units utilise tubular primary heat exchanger and a secondary condensing heat exchanger with an aerodynamic profile and 4-pass flue gas circuit. Model Range The ULTRA condensing units consisting of five models is available with heat outputs ranging from 25kW...

Advanced Heat Exchanger Technology Optimum Economy and Fuel Savings As the flue gases pass through the secondary heat exchanger, the extra surface area cools the flue gases below 45°C causing the water vapour to condense and release its latent heat. In times of rapidly increasing energy costs, reducing energy consumption makes sense both financially and environmentally since this also significantly reduces CO2 emissions. This heat, which would normally be lost to the atmosphere via the flue, is instead transferred into the building hence less fuel is used to achieve the same heat output....

Primary Heat Exchanger Manufactured from high quality corrosion resistant steel, the entirely new primary heat exchanger reduces thermal stress for enhanced life expectancy. This tubular heat exchanger is welded to the burner box using the newest robotic welding technology to form a highly resistant and durable assembly. Secondary Heat Exchanger The secondary heat exchanger is manufactured using high quality corrosion resistant materials, the non-welded design of the heat exchanger reduces thermal stress for enhanced life expectancy. This heat exchanger constitutes the second part of the...

Air Distribution Flue spigot supplied as option at point of order. A high capacity axial flow fan is fitted to all units for improved air throws and reduced stratification. The fan operation is controlled by an integral controller which delays the fan start up until the heat exchanger has reached operating temperature and continues to run the fan after the burner has switched off until all useful heat has been dissipated. An optional economy thermostat may be fitted to heaters installed at high level to recirculate warm air down to working level when the burner is switched off. Horizontal...

Enhanced Reliability and Safety Units may be suspended or alternatively mounted on a suitable non-combustible support. Four integral suspension points complete with an M10 female thread are provided to each heater. The balanced flue terminal provides both the combustion air inlet and flue outlet from a single building penetration. The terminals are ordered separately from the heaters to suit either a wall or roof outlet. Additional flue and combustion air pipes may be added, up to a maximum of nine metres of flue pipe, plus nine metres of combustion air pipe. (This reduces by 1.5 metres for...
