Deceptively small, but very powerful, the Potterton Promax SL is a slim-line, wall-mounted heating only boiler, suitable for installation in kitchen wall units. Hot water storage can be provided by a separate source, such as an indirect cylinder. The five models in the range feature a choice of outputs to suit different sizes of homes.

The Potterton Promax HE Plus automatically adjusts the heat output to meet your demands (up to 30kW). It provides simple heating solutions, whatever the size of your home.

As you would expect from Potterton, all boilers in the Potterton Suprima HE range meet the requirement of the Government's energy efficiency legislation. Plus the wide range of outputs means that whatever the size of property, there is a Potterton Suprima HE that is well suited to the task.
