Thermostat replacement on CONSORT HeatFlow Heater?

I need to replace the thermostat on my CONSORT HeatFlow (BFH2T-90) Fan Heater.

Any ideas where I ought to try please ?

Have dropped Consort a line, as well as the KEMA KEUR the stat manufacturer.

Obviously any make/model that will do the job will suffice.

Can send picture to interested parties.
