hi all reading how long it takes for sm heater to warm up. i was thinking of fitting a mains engine block heater .has anybody done this.and how successful was it ?

No experience of the heaters, but I'm sure Google will have something, I think one unit was called Holts HotStart, but don't know if it is still available. BUT, why do you think the Snow Monster takes a long time to warm up? Exactly what engine are you looking at?

As I have posted before, and confirm from my journey to work this morning. I left home at 0430 with an air temp of -3 showing on the MFD. Within 3 miles I could start to feel heat out of the dash vents, and within 12 miles the car was at full temp (oil and water). I don't think that is bad and is no worse than my old Freelander, with the Fuel Burning Heater.

No experience on a Yeti - mine's about to be ordered with a heated windscreen and heated front seats as soon as the pano roof becomes available again. I fitted a Kenlowe preheater to my Landie 90, which was straightforward to do, and worked really well in terms of full power heating available as soon as the engine was started. You just need to remember both to plug in the night before and more importantly to unplug before driving off!

I had a Kenlowe on my last-but-one Defender too (it was fitted when bought) - a marvellous luxury, albeit only for those unusually cold periods. I guess it does have to have an effect on engine wear, too.

But my much more civilised Yeti heats up fine, like Graham's, and if things are that perishing, there's always the seat heaters in the meantime. It's really not an issue.

I go along with this. I have the same model as Graham and I find that warm air is coming through within the first mile of driving. The water temp gauge is a different matter, it takes up to five or six miles before the gauge reads 90C
