The boiler was of a treacherous material and weak shape, and unfit to bear safely the 7 lbs. pressure the column of water from the cistern would give. The fire also acted on the sides of the boiler without any intervening brickwork. If a closed top boiler is used, there should be a dead weight safety valve to prevent pressure. A far safer plan is to have the kitchen boiler with open top and the circulating heater within it, so that it can never get overheated, as it only obtains its heat from the water in the open boiler.
