I made an auxiliary heater,using the three glow plug 'hedgehog' type water heater from a Renault Clio 1.5 dci.
Combined with a temperature sender from a VW that turns off at around 55℃ and a relay for each plug(spare red ones from an Alfa!).
It works rather well,in as much that,with the heater control on auto,(pre interior facelift model,so no auxiliary heater of any sort),by the time the fan kicks in,the air from the heater is noticeably warm. . . . .the best bit being that I dont have to 'drive it like I stole it' when the engine is cold to avoid hypothermia!(tbh I got used to freezing,just couldn't bring myself to thrash a cold engine!)
