To assist with determining the correct size connection for replacement units or units to fit your current system, we have created a table of external and internal thread sizes.
This calculator is designed to assist the specification of a cylinder by determining the amount of hot water available from a cylinder of a specific size; this can be particularly useful in situations where space for a cylinder is limited.
Uninsulated Cylinder Calculator
This calculator is designed to assist the specification of a cylinder by determining the size of the cylinder from it's circumference and insulation thickness; this can be particularly useful in situations where a replacement cylinder is required, but due to the insulation it is difficult to determine the size of cylinder required.
Please note - The final figures are approximate and should be rounded to the nearest standard diameter (375,400,450 etc.)
