I have been in talks with a manufacturer of automotive fan switches and we have come up with a prototype thermostatically controlled switch for the fuel line.
This means you can monitor the temperature of your heat exchanger - or (as I want to use it for) put in an electric pre-warmer which will turn off when the fuel reaches a certain temperature (75deg C)... It could also be used by the two tankers to autmatically switch over to veg oil as soon as the heat exchanger was hot enough...
The switches are made by a fairlyy large manufacturer of autmotive components - from machined aluminium (best material for heat transfer).
If any of you guys would like one - they are turning out to be £50 +VAT.
Let me know!
