Our new Discovery Zone is in the 1916 extension to the Boiler House which was built to house the Babcock & Wilcox boiler of 1916. The boiler has been left as a skeleton so that you can see how it was constructed and functioned.
In the original part of the building are two Babcock & Wilcox boilers, the left hand one of which was installed in 1906 and was returned to steam in 2018 with the aid of money from the Heritage Lottery Fund. Only four Babcock & Wilcox boilers survive to this day and Twyford has three of them. Running along the ground in front of the boilers you can see the railway track for the wagons which brought coal to fire them.
Against the west wall is the pitman and bell-cranks by which the steam engine drove the pumps down the well.
