Gas Fired Condensing Boilers

The Corolla Pack 503 - 504 series of condensing, pre-mix, modulating boilers contain either three or four 50kW heat exchanger modules within a single casing. This provides total boiler outputs of 150kW or 200kW. To simplify installation and maintenance each boiler comes complete with an integrated hydraulic connection kit and flue header kit.

Featuring efficiency figures as high as 108.7 nett at (30%) part load, and European Class 5 NOx emissions, the Corolla Pack has excellent environmental benefits, and far exceeds current requirements for Part L Building Regulations.
