Rated 4 out of 5 by Perfect replacement Perfect replacement for my Biasi Garda HE 28kw. The pipes all lined up. However the Gas pipe needed adjustment in height only. Easiest money my Gas safe engineer has made in a long time I suspect! 17 Nov 2015
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

Answer: 
Hi, as far as dimensions, flue position and piping, the Riva Plus 28 would be the best match, the 28KW will provide 11.6 litres of hot water per minute, where as your old 32kw would be slightly better at 13.1 ltrs. If you did want to upgrade from this, the Advance Plus 35kw would be a good replacement as it provides 15.6 ltrs hot water and comes with a 5 year guarantee, having said that there would be more work involved as the flue is central on these models.

I want to replace my old Biasi boiler 9yrs old (Biasi Riva Compact M90E.32S) On this site I was told the Baisi Advance Plus 30kw would replace my old boiler when I asked a plumber to take a look he say's that the gas pipe is 15mm and needs to be changed to 22mm although at the meter it is 22mm this means walls and floors being taken up a big disruption for anew boiler will this boiler fit a 15mm gas pipe if the gas pressure is correct

Answer: 
Hi, Thank you for your enquiry, pipe sizing for gas is a very precise matter, the distance of the boiler to the gas meter will determine what size pipe is required, pressure is important but volume is equally important. If your pipework cannot handle the amount of gas required, the boiler will not perform. Your old M90E 32 (32kw) should probably have been installed with 22mm pipework (it's hard to say for sure without seeing your system) but this was the reason we suggested a 30KW replacement, believing the pipework would have already been 22mm.
While you may have got away with "under gassing" your old boiler the Advance Plus 30Kw uses a state of the art pre-mixed burner and it's essential that it has the correct amount of gas supplied. To me it sounds like your installer is giving you the correct advice.

Answer: 
As a former CORGI and now GasSafe registered engineer I wouldnt advise fitting a boiler with this output to a 15mm gas supply ! Depending on the distance from the meter the length of pipe run. number of fittings in the run and the gas requirements of any other appliances on the system, you will probably find that the installers/maintenance book specifies a minimum 22mm gas supply up to and connected directly to the boiler.
I would advise that, if possible, you check below the floorboards near the boiler to see if the present supply has been reduced in size near to the boiler, if thats the case then just increase the pipe size from there right up to the boiler, when up and running, using an analyser, ensure the flue gas readings are correct throught the range, if they are its job done, if not you may have to increase the pipe size to 28mm from the meter to around half way into the property, the calculations for all this, the fitting of pipe & the boiler, should ONLY be carried out by a qualified GasSafe engineer with the correct equipment as the commissioning sheet in your book will need to be completed to validate the warranty, I hope this helps
