The secret to the MB5’s five star efficiency is its multi tube heat exchanger combined with a modulating gas valve which minimises gas usage and modulating room air fan. The advanced technology of the modulation is able to match the load requirements of your home by reducing its heating capacity as low as 10%*. This not only reduces gas consumption but also reduces electricity usage of the fan motor.
