Rated 4 out of 5 by biasi over the years iv fitted more than 30 of these,iv one at my house and it has given me no problems as with any wet heating make sure the radiators and pipes have been flushed out ,use a cleanser and inhibitor,fit a unit to trap magnetic and particle debris and keep the correct concentration of inhibitor every 2 yrs and not much can go wrong.Most important have it fitted by an experienced and qualified fitter. 29 Dec 2014
Rated 3 out of 5 by good all round combi my 16 yr old Biasi broke so decided to change it for a new model. After researching the technical data on this combi I decided to buy it as it was an almost direct replacement for the old 424s. Apart from the gas pipe everything lined up including the flue which had to be moved down and over slightly. The only quib was the expansion tank was off centre so I had to realight it but in doing so loosened off the pipe which then leaked when I had fitted the boiler, so it had to all come off again. Not pleased but once installed its a good combi for £550! 17 Dec 2014

Hi, Thanks for your enquiry. Your existing boiler is a standard efficiency model, although the Riva Plus 28 would replace this the flue position would be different (Off set) so if you are tight for space and want to keep the same foot print on the wall, I would recommend going for the Advance Plus 30KW or even 35KW, these models are 700 x 400 x 290 (around the same as the M90E) They have a central flue, better hot water flow rates and come with a 5 year guarantee. Both the Riva Plus 28 and the Advance Plus models will also save you money on gas!!
