Our boiler is 20 years old when the heating control knob broke. After I removed the broken shaft from the boiler it ceased to heat the radiators. We were very relieved to find that the controller was still available. We received the replacement within 24 hrs so our heating was restored. The quality of the replacement was exactly the same as when our boiler was first installed.

Perfect replacement for the temperature control on our Worcester boiler. Be sure to order the correct length as the other control knobs have shorter stems. In this case, size is everything!

My boiler was clicking and whirring on-and-off virtually all the time because the previous control knob had broken. This is an exact replacement and worked instantly to solve everything. Seemed a little expensive at first but packaged very well (it is quite delicate unless in a box) and this raised the postage cost... so much cheaper than getting out a Corgi engineer anyway! Thanks very much

It's either NOS or a perfect copy so exactly like the original - and like the original the stem will probably snap off because of it's flimsy design.

Its a control knob to alter temperature range from low to high, without it its just one constant temperature.
