It's the logical way to do it. Problem with any heat store is whether it will work when needed. If it wasn't fully 'charged' by the previous journey, it's not going to work when needed. And one which might work the next morning might not work if the car isn't used every day.
You wrote to BMW UK didn't you? The reply will have been from a sales/marketing/PR bod.
Sand wouldn't be latent heat storage either - it has to be phase change for the name, and for it to actually work. I see it isn't necessarily sodium acetate though.
Agreed - it does appear to be all-model and covering a fairly wide period, going by the references throughout it to other model ranges. E30, E31, E32, E34, E36, E38, E39, E85, R50, R53
Option code 907 is interesting... "James Bond Edition"
ne and which BMW UK say is correct ? Where is the fuel burning cabin heater coming from ?
Perhaps. Who knows? And anyway he may have researched his reply whoever he/ she was. Who knows. This is all conjecture.
comment about using sand to store engine heat to be released later. This is closer to what I remember. After all electric storage heaters use bricks o r concrete blocks to store heat. These obviously would be too heavy for use in a car, hence possibly, the concept of using aluminium.
Not having any knowledge of how a latent heat store works my tenuous grasp takes it to mean that heat from the engine is stored in a chemical solution . By any possibility could this solution be contained in a lump of aluminiu m ?. Could that be where I got the idea from? As I had no real interest in what was an expensive extra I would not have studied it in detail
You've obviously never visited a BMW garage. They heavily promote used vehicles. If you are essaying to conjecture a difference between BMW UK and their dealer network you,re living in lala land.
And so the denial continues. More to be pitied than laughed at. Now you nee d a comment from an owner. Why should I bother pointing you towards one. Re search it yourself. They're out there . No doubt if you turned one up you'd then insist on it being shown you fitted to a car.
