Ferroli Optimax 25 OV
The Ferroli Optimax 25 OV is an energy efficient boiler and is rated in the A Band for SEDBUK (Seasonal Efficiency of Domestic Boilers in the UK). The boiler is a condensing gas boiler and is highly effective, releasing smaller amounts of harmful carbon dioxide and NOx emissions in to the environment. This also saves the consumer money on their heating costs as the boiler wastes less energy.
The Ferroli Optimax is a fairly small boiler only 720mm in height x 400mm in width x 370mm depth. These dimensions mean that the boiler will fit into a consumer's home with little trouble and its white casing and simplistic design mean it will look clean and smooth and fit unobtrusively within a room or airing cupboard.
Ferroli complies with the benchmark initiative to improve the standard of central heating systems and installation. The boiler is designed to be reliable and comes with a Ferroli guarantee on all parts and labour for five years.
