van heater's - I know some use fan heaters oil rad's but if you have to park on street like i do then these are the daddy's - gav ccc been on my case to post my van heater that was used last year to keep the van toasty so here's the link
http://www.bluebird-type2.co.uk/heat.htmPropex heatsource 2000 standard one £425
ive no connection to bluebird , just they was the cheapest last year ....

they was cheaper last year but the bad last winter probley has driven up the price , but if you ebay them or google there are lots around cheaper .
easy install - just two 1inch holes in floor for air and exhaust . set the temp controller and leave to tick over in the night . ( they have a quite V8 sound burble which is cool !! )
good bit of kit .
easy to remove for new van like im doing at min .
