we fit this boiler for council contract in aberdeen and it is the worst boiler I have come across in 25 years by a country mile.everything from the fan,pcb,air pressure switch,diverter valve among other things needs replaced within weeks or days of install.you could get a potterton promax for about a £100 more and have no problems at all and get at least 10 _ 15 years out of it
