Potterton Promax HE Plus
Offering three models with fully modulating outputs ranging from 9.14kW to 30kW, the Potterton Promax HE Plus is a highly efficient central heating boiler with an energy efficiency rating that allows up to 19% more heat produced from the same amount of fuel in comparison to a conventional boiler. In addition to the SEDBUK Band A rating, the Potterton Promax HE Plus also has a very low level of NOx (nitrogen oxide) emissions and is awarded with a Class 5 rating, which is the lowest for central heating systems. This makes the Potterton Promax HE Plus ideal for the environmentally conscious.
The Potterton Promax HE Plus is visually almost identical to many other Potterton boilers, with the standard clean white casing with the grey panel at the bottom of the system concealing its simple and user-friendly controls. It is a wall-mounted central heating only boiler, with hot water possibly provided by a seperate source which could include an indirect cylinder. Although a little larger than other Potterton systems, it is still compact, and can also be sited in an unventilated cupboard for convenience with a wide range of flueing options available which allow the Potterton Promax HE Plus boiler to be sited in less conventional and more convenient areas.
- Available in 15kW, 24kW and 30kW wall-mounted models.
- Lightweight and compact
- Easy to install
- No compartment venting required
- Can be sited in more convenient areas with the comprehensive range of flueing available
- Rated SEDBUK Band A for energy efficiency

- The lowest class, Class 5, NOx emissions
