[QUOTE="Fowler VF, post: 4157754, member: 57664"] Agree entirely. My guess is that the control system we saw the photo of is keeping that 10% blower rate up so that if there is any wood left in the chamber it isn't being starved of oxygen and is able to quietly smoulder. Starve it of oxygen and it will have a tendency to gasify; chamber would build up with wood gas and next time you opened the door or switched the blower on the gas would go up rather quickly. Not so much of a problem with a smaller boiler but a bit of whoosh on a big one with a big door! If you have put more into the thing than is needed to heat up the buffer tank and immediate needs then even that 10% blower rate will quietly go on producing more heat and give you the issues you had. I have seen systems where as well as the over pressure relief there is also a water dump valve run by a thermostat, can only really do this if there is an auto top up system filling it back and in any case the issue is then one of a lack of correct inhibitor treatment in the fresh water. That sort of mechanism isn't meant to be one in regular use, its just another safety feature to back up the pressure relief. [/QUOTE]
