Ferroli Optimax HE 25S

The Ferroli Optimax Range of condensing system boilers are highly efficient and equally as reliable. The Optimax HE 25S is the middle sized model in the range with a 25KW output and can easily provide enough energy for a small 3 bedroom house. These Ferroli boilers are wall hung and have recently been redesigned with stylish compact casings. The Ferroli Optimax HE 25S has the following key features and benefits:

  • An efficiency rating of over 90% which gives this range of boilers a SEDBUK rating of 'A'.
  • An integrated automatic bypass valve which keeps the flow rate through the heat exchanger to a minimum at all times.
  • An aluminium heat exchanger for added energy efficiency.
  • A high density foam lining within the aluminium casing for ultra quiet operation when in use.
  • A very user friendly control panel with an easy to read liquid crystal display. The panel can be used to control every aspect of the boiler's operation.
  • An in-built heating pump and expansion vessel which saves on space.
  • Easy installation into a variety of home locations including the kitchen, utility room or airing cupboard if preferred.
  • Easy servicing and maintenance.
  • The option of natural gas and LPG models.
  • A 5 year parts and labour guarantee

Ferroli have designed the Optimax HE 25S to be compatible with both S plan and Y plan fully pumped heating systems which adds to the boiler's versatility. It can also be used with the Ferroli range of underfloor heating solutions.
