Unvented Cylinder - Standard Specification (Cased)
Unvented Cylinder - Red Cased Show Unit
Mixergy Tank - 180 Litre Stainless Steel
Unvented Cylinder - Red Cased Show Unit2
• For use in a pressurised system
•Available in both Copper & Stainless
Unvented cylinders are designed to work at a high pressure and offer superior flow rates. This is beneficial for as it allows high water pressure for a power shower and the ability to feed several outlets. We manufacture unvented cylinders in both copper and stainless steel which both offer their own unique advantages.
Unvented cylinders have no need for a cold water feed tank and with it being supplied directly from mains water, it offers far greater flexibility than a traditional vented unit. With the unit not requiring a gravity feed or pump it can be placed anywhere in the premises.
Unvented cylinders also have the flexibility to work on a wide variety of systems; they can be fitted with coils for solar heating, heat pumps and underfloor heating. As all units are manufactured in house, they can be made to bespoke customer specifications such as tapping size and positioning.
A range of standard sizes and formats is available in the Size and Specification tab. Alternative heights from 600mm to 2000mm and diameters from the list are also available where space and water volumes are at a premium.

Matching customers' requirements is particularly important when space is at a premium, so the most common customisation for a hot water cylinder, is the “mixing and matching” of the various heights and diameters that we offer. As additional parts of a Bespoke design, the customer is able to specify a number of options including, connection sizes/positions, insulation thickness, whether it is manufactured from copper or stainless steel (see our Copper vs. Stainless Steel page for a comparison), and the finish of the unit (the silver metal case being the premium option). It is also possible to combine different types of cylinders to result in the optimum solution for your individual situation. We can offer design drawings prior to manufacture to ensure that all connection sizes, positions and functions are to the customer's requirements.
See our Bespoke Products page if you require a unit which may be slightly out of the ordinary and please contact us if you require any advice.

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.
Uninsulated Diameter Calculator
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.
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.)
