Can anyone tell me the location of the small condensing tank in the 24i junior greenstar - the boiler appears to fire up then the green LEd light goes out - no heating to any radiators. The hot water is working fine. Have bled the radiators and the water pressure is fine. Want to locate the condensing tank to see if it needs cleaning out.
Any advise would be great

if condensate trap was faulty this would also affect hot water,sounds like the diverter valve may not be opening to allow heat out to radiators
