Have recently refilled my boiler after draining down for repair .It now appears to be getting too hot.The casing is very hot and the water is going over the overflow into the make up tank.Is it likely to be a air lock within the boiler or could it be the thermostat in the boiler not cutting the boiler out quicky enough.Would be very interested in anybody thought on this??

Well it could be either, but following on from a drain down I would suspect an air lock, this would cause the boiler to cycle. A faulty thermostat (or damaged, not replaced etc) would cause the water to boil continuously. What was the repair?
