I have been advised by Haworth Heating to use the less well known Fernox inhibitor Alphi-11 in my Bubble 24v Pressure jet boiler. This boiler does not have Bollin pumps, but equally sensitive to rusty sludge magnetic drive Bosch ones. http://www.screwfix.com/prods/59505/Plumbing/Central-Heating-Treatment/Fernox-Alphi-11-5Ltr http://www.fernox.com/files/Fernox/Content/PDF/English/Alphi%2011%205L.pdf which contains inhibitor and more importantly the mono-propylene glycol antifreeze Bolin specified.
