Combination Copper Hot Water Cylinders

Combination Copper Cylinders by Gledhill

FORTIC TANK - Hot water cylinders with built in header tank

 

What is a Combination hot water cylinder?

A combination cylinder (also known as a Fortic Tank) is one that incorporates a cold water header compartment that one would normally associate with a separate header tank. The convenience of a simple one-piece installation is clear and the design lends itself to properties like flats or apartments where a lack of loft space makes it difficult or impossible to site a header tank.

Drawbacks of combination type hot water cylinders

Combination cylinders are not the best solution to all installations. Resulting hot water pressure from a combination cylinder is generally poor because the header section (the bit that creates gravity pressure on the cylinder) is at such a low height. (note: the higher the header from the outlet point, the higher the pressure due to gravity)

The low pressure associated with combination cylinders can be frustrating. Mixer showers tend to suffer noticeably. The temptation exists to install a booster pump to improve performance, but consider carefully before you do so. The volume of cold water contained within the header can often prove inadequate to keep up with the extreme demands of a booster pump so you risk running your system dry fairly quickly. This is not good for the booster pump and can cause damage.

All cylinders are fully insulated with a thermally advanced and environmentally friendly Envirofoam jacket, offering continued high performance throughout the life of the cylinder. At the end of it's life Envirofoam decomposes so it's also environmentally friend too.

Positioning tappings to your specification does not normally attract a supplementary charge

     
When sizing a cylinder remember the stated dimensions do not include the thickness of insulation. You must add the thickness of insulation to the cylinder dimension to obtain the finished size. This is most important if the cylinder needs to pass through a doorway or access hatch. Make sure you have enough room to make connections and service immersion heaters.

Illustrations are for guidance only and should not be interpreted as an exact representation.

 

 

Note: Cylinder illustrations are for guidance only. The relative location of the hot water outlet to the immersion heater may positioned to customer requirements thereby enabling easy fitting/retrofit. Please refer to Designing a Cylinder section.

In the cylinder industry nothing should be assumed or regarded as 'standard'. Features such and as the position of connections, a shower take off, drain, boiler control stat/sensor pocket or any other item should be stated as a requirement, not assumed.
