Boiler thermostat replacement

[BobRK]

I have an old MYSON Velaire 110/135 oil fired boiler with a CL6 PO117 thermostat which has failed. The only supplier I could find on the internet says they are no longer available and there is no alternative.

The thermostat adjustable knob on the front panel, see photograph, sets the water temperature. When the water reaches the temperature setting the thermostat opens a pair of 240 volt electrical contacts and the boiler switches off. A very basic form of control really.

Does anyone know of a thermostat that I could use as a replacement?

Thanks for reading.

how long is the capiliary/ what size is the thermophial?

 

One of these is the normal modern style, if you can find a way to mount it inside the housing. They notmally clamp onto the end of the thermopocket in the boiler

I wouldn't mind betting the only difference is the length of the capilary tube and if the one above is 134 mm and your original part is 117 mm
