Our main business is to manufacture and supply retrofit heat exchanger coils to installers whether they be D.I.Y or professional as 1 off's or in large batches we cater for any need. The design is as flexible as possible to suit as many "standard cylinders". These are covered by our main product range which is 800mm long for replacing top entry immersion heaters or 350mm side entry units. The dimensions are listed in the product menu.

We can also cater for the non standard cylinders like the mains pressure systems like "megaflo". These have a non standard 1-3/4" bsp thread. For more information select mains pressure in the Products menu.
