are the dimensions with lagging if not what do you add for lagging, what are the pipe fitting sizes
The dimensions of the vented foam lagged cylinders on our website are for just the cylinder as this is how the manufacturer lists them. The lagging is 35mm on standard cylinders and 50mm on economy 7 cylinders.
So for standard cylinders you need to add 70mm to the width (35mm each side) and for the economy 7 cylinders you need to add 100mm to the width (50mm each side).
The immersion heater connection is 2.1/4" and the other pipe connections are generally 1" but on some of the larger size cylinders the connections are 1.1/4"
