V40 Engine Preheater

Toxster · Jul 19th, 2017, 12:27

Having just acquired my first ever Volvo (V40 CC T3 -brand new on personal lease) I'm thinking about an engine preheater....

A few questions about these...

I've seen an electric only one (linked below) and the ebay equivalents which are much cheaper. The reason I'm thinking electric is that it's a lease car, so it'll have to come off when the car goes back and I want something that is not too destructive to fit and remove.

These are all 240v, so clearly designed to plug into the mains. I have to park on the street, so the question is, can these run off the battery as well? I could always fit a transformer and maybe even a second battery.

Any help appreciated, thanks.

Update: If I'm correct a 500w heater that should run for three hours will run a normal car battery flat in an hour, so this might not be viable....

I didn't know these were an option in this country. To be honest unless you have a bigger engine car or are in cold climates, they probably would not be of too much benefit as modern smaller engines will warm up fairly quickly.
I had one on a Saab 95 3.0TiD about 12 years ago and it was driven by engine fuel. Was quite good but could kill the car battery if left on for more than 30 mins as AC would also start to warm the cabin.
Talk to dealer re option open to you as may only be a factory fit anyway.
