The Brizer is activated automatically by a thermostat, slowly pumping out the heat from the roof space, in so reducing the temperature in the roof space by 15 centigrade on average.
During the summer months, the average temperature in the roof space is 50 centigrade, but with the aid of the Brizerthe maximal temperature will reach only 34 centigrade.
The drop in the roof space temperature affects the temperature of the rest of the rooms under the roof, reducing it significantly.
