This is just ,me repairing an old radiator oil heater, couse it did burndown internal termostat regulator.
I simply bypassed termostat and now its working again without termostat regulator.
Im sorry abaut video quality.
I am not an electrician and i dont have an electrition certificate, so dont do this at home unless you do it on your own risk.
Couse there is always chance to do something wrong.
