Stainless Steel cylinders can initially be a more cost effective way of storing hot water when compared to Copper cylinders, especially when it comes to Unvented or Pressurised units. This is because the superior tensile strength of stainless steel, allows it to withstand a much higher pressure than a copper cylinder of the same wall thickness.
However, this initial saving could, at some stage, be outweighed by the superior heat conductivity (and therefore efficiency) of a copper cylinder, as fuel bills would inevitably be slightly higher.
We would advise that the benefits of copper cylinders do outweigh the benefits of stainless steel and if your budget will allow, a copper cylinder is always the best option.
For a detailed comparison of the two materials please see our Copper vs. Stainless Steel page.
we are the only UK company currently offering a custom design service for stainless steel cylinders (standard specifications are also available). As with our copper cylinders, you are able to customise your stainless steel cylinder to a combination of different requirements.
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 Diameter 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.)
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.
