Cant comment on boiler reliability cos dont have a great deal of experience with them.
Its a high output boiler at a reasonable price.
cannot comment on parts costs or warranty.
You didnt specify what work your installer will be doing. Full system? converting from system to combi? etc etc so we couldnt really justify whether your price is right.
Plus we have not seen the job and dont know position installer is in, in relation to what pipework he has to upgrade, electrics to bring up to date etc etc etc
