BUYability Favourite Features
The biggest of Ferroli’s system range of boilers and it shares the same characteristics as its sisters and brothers. An advanced premix burner system will keep the gas bills down and it works well with the company’s additional heating systems (solar and underfloor). And, say the company, it doesn’t make a noise.

Great top-end boiler which will do the job of keeping a larger property snug. Ferroli may not have a name you immediately recognise, but if your installer recommends one, don’t pull a face. These boilers will save you pounds!
