Excellent boiler, 80,000 btu.
As far as after sales goes Ferrolli also do the same boiler but in disguise. Its called the F24, it has a better looking cover, thats the only difference. But included in the package is a filling loop, a programmer (internal) and a 2 year warranty.
Personally mate i've had no trouble with Ferrolli, an F30 I fitted last Thurday had a suspect pressure gauge, resolved Wednesday this week!
Technical advice kind & friendly and provide an answer.
Make sure the Boiler is commisioned they are quite hot on the fact that the Benchmark is completed.
