Back Engineering – Case 101

SBH Radiators offer a wide range of bespoke opportunities for our customers. In addition to making one off designs, shapes and sizes we offer a ‘back engineering’ service. Many customers have the dilemma of considering a new radiator but don’t want the hassle or cost of moving radiator pipes and being left with secondary holes in the tiled wall where the original radiator was installed. Our ‘back engineering service’ makes it possible for the customer to replace a radiator without the added expense of changing tiles and plumbing. The very nature of this service which separates us from the competition. Its simple, one out, one in.

Our customers problem……

Our client required the back-engineering of 9 radiators in total. The end-user did not want to go through the expense of retiling walls and flooring, as well as expensive plumbing rework. The original radiators were made from steel chromed and employed round and hexagonal tubing. Two of the radiators are fixed to the wall and floor.
At the customer’s request, we were asked to make the radiators from 316 stainless instead of our normal 304 grade. 316 has a higher nickel content making it more resilient to corrosion.

Step 1

Firstly we were lucky to have access to the old radiators which were made available to us. We set about and started to make templates for our manufacturing facilities to follow. The process started with laying each radiator on sheets of card to mark out the mounts and importantly the fixing holes. Measurements were taken from the 3 fixing points on each mount in relation to each other. Then the distance to the opposing mounts, each mount had 6 measurements that had to be recorded.

Step 2

All the dimensions collected had to be transferred to the templates, All measurements were recorded and double checked. These details will be used later to create a CAD drawings. Accurate measurements were taken for the plumbing points, again these details were added to the template and later used in a CAD drawing. New mounts had to be designed to accommodate the fact that the old radiators plumbing points formed part of the mounts.
