Every three or four weeks I need to de-air the towel radiator in the bathroom. This is the highest Radiator in the system. A friend, who is a retired plumber, suggested that I have a small leak somewhere in the system. In his day he would have solved it with the addition to the system of a "leak fixing additive". But he does admit he is totally out of date and things might have moved on from this. Can anyone suggest the best way of solving this. I have searched the visible pipe work, but to no affect. A Worcester Bosch Greenstar 25 combi boiler is fitted. Peter
