I hope you don't mind if I reply. We picked up our Valencia three weeks ago and have had 2 weekend breaks in it. We previously had a Series 6 Wyoming. I was sceptical about the radiator heating as I had read that it is slower to heat up than warm air and the controls not easy to work out. I was wrong on both counts - if you want, there is 3 kw of electric plus your gas as well and it heated up wjhilst we were setting up and doing our separate tasks - I used maximum power for about an hour then turned the gass off and the electric down to 2kw. I sat down with the manual and can now work our heating, boost for hot water and use the night-time setting. Heating is excellent. Bathroom can be a little cooler than the rest of the van, but as others have said, just leave the door ajar and you won't notice, or spend less time in there!
Van itself is excellent in my view. Very comfortable seating, no issues.
