Having a hot water cylinder made to your specification
You may have an installation where an 'off-the-shelf' cylinder just won't fit. We can therefore offer a bespoke service whereby a cylinder can be manufactured to suit.

Maybe a cylinder is not the answer. Hot water storage comes in many shapes and sizes - square, rectangular or even triangular!

We have had many cylinders manufactured to solve numerous requirements - both physical and operational.

  • Loft conversions
  • Hallways and landings
  • Restricted cupboard space
  • Irregular shaped storage
  • Farm and agricultural use
  • Vented storage with additional mains pressure hot water take off

Please don't hesitate to give us a call if you would like advice or wish to discuss your requirement.

Improving the performance of a cylinder
It is possible to improve the performance of a cylinder by upgrading the properties of the heat exchanger, adding a second heat exchanger and/or increasing the amount of insulation around the cylinder.

By putting a high performance heat exchanger into a cylinder you could greatly reduce the amount of time the cylinder takes to reheat from cold - the recovery time. This can be particularly useful if hot water usage is high but you cannot, or do not wish to have a huge amount of hot water stored. A smaller cylinder with a high recovery heat exchanger can often produce as much hot water per hour as a larger standard cylinder. A smaller cylinder with high recovery can solve a problem where space is premium. This is not always a solution, but is most certainly an option.

A high recovery heat exchanger can also prove economical to run. As more heat is imparted to the cylinder more effectively, a boiler can operate more efficiently and may need to cycle less often and for shorter periods.

The addition of a thicker insulation jacket has obvious benefits. By reducing heat loss your stored water remains hotter for longer - reducing the need for reheat and boiler activity. Whenever you consider additional insulation remember to check the overall cylinder dimensions (including insulation) if you intend to install into a confined space.               Click here for more information on cylinder insulation

Improving the performance of a cylinder will add modest cost, but over the life of the unit should represent a significant saving on running costs.

Adapting a cylinder to your specification
You may require a standard size and shape of cylinder but need the tappings or bosses relocated to match as close as possible into existing pipe positions. This is a common requirement and often has no effect on the price or lead time.

Example: If you wish to run power showers, It is possible to incorporate dedicated shower take offs on a cylinder.

Should you need to order such adaptations it is important we all speak the same language when describing position and dimension. For this reason we use a system as illustrated below.

Please note: Whilst every effort is made to position tappings and bosses to the required positions it cannot be guaranteed that minor adjustment of existing pipework will not be necessary. It is for this reason important your measurements are accurate.

With any special order we will require a sketch of the cylinder you require. This can be faxed, posted or emailed to us and should look roughly as follows:

For a cylinder you should draw a side-on view marking the positions of each tapping and boss required, together with the floor to centre measurement. A combination cylinder should be shown like this. Once again marking the position and dimension from floor to centre of any tappings or bosses. You should also provide a top view of the cylinder or combination tank. Mark the position of each tapping or boss as though you are looking down on  clock face. (6 o'clock typically represents the front)


So a typical sketch might look something like this

 

In short, you should provide as much information as you can so that your requirement is absolutely clear.

Indicate on your sketch what each marking represents together with it's position and height from floor to centre.
