Hi, have Lunar Clubman SE with the Alde heating system, the expansion tank and 12v pump are located in the side wardrobe. for most of this year since purchase it has been used in France, ie hot water only, on return to UK and a cooler temp put on the full heating system. No problems everything gets hot as it should only problem is there is a boiled chemical smell in the wardrobe, in stinks quite a bit, checked the usual, bleed the system, checked the level all ok, it just stinks in the wardrobe. anyone had any similar problem or could offer any solution.
