worchester boiler 24i problem ,how high should the pressure bar go up when radiators are on.mine is on 1bar but when switched on goes up to 4bar,is this normall.
normally 1 or 1.5b check to see if water is running out your safety valve when heating is on normally a 15mm pipe outside somewhere if water is running out it may be a faulty pressure vessel or it may be choked
