I caution the use of oil for heat storage as it lends itself to environmental hazard and the system you are describing is full of net losses.
Water is hugely better at storage and heat transfer. Much safer with the addition of propylene glycol for antifreeze. (food grade). you can drink it!! if it leaks into the environment no harm!!!!
If you are interested I can provide you with first hand experience to my system that has proved itself.

I would love to hear some first hand experience information. By "flat plate" are you talking about a box with tubes in it?
