Product Characteristics
The microGENUS HE is a direct evolution of the familiar microGENUS range, which is now one of the UK's best selling gas boilers. The microGENUS HE is SEDBUK Band B rated boiler which is fully compliant to the latest building regulations. The microGENUS HE achieves this level of efficiency by incorporating an additional latent heat exchanger or recuperator, which significantly increases efficiency by extracting heat from the flue gases. The benifit of this is that it is based on existing technology and offers installers known boiler layout whilst meeting the requirments of the latest regulatory changes.
