The Main Combi 24 HE and 30 HE are combination boilers designed to suit most homeowners' needs. With clean and simple lines, they're easy on the eye and simple to keep clean.

Adjustment of hot water and heating output couldn't be more straightforward. Using the rotary controls on the lower front panel and three small lights, you can confirm at a glance that all's well or be alerted to a problem such as an interruption of the gas supply. Of course, being a combination boiler, hot water is always the priority service, and it's always available on opening a hot water tap. Output to the radiators is automatically adjusted for maximum economy and an inexpensive timer can easily be fitted into the fascia to control heating on/off periods.

Based on the Main Combi 24, the Main Combi 24 HE and 30 HE both include a secondary heat exchanger to extract more energy from the same amount of gas. They meet the very latest Building Regulations concerning the efficient conversion and the conservation of energy. Simply put, they're designed and made to minimise your gas bills.
