Have you looked at Crusie Aire or Marine Aire? I think you may find those two options less expensive than Webasto. I think 12000 Btu will be more than enough (might be too big) for your 31. I would ask other 31 owners what they have. I have used my reverse cycle heat with water temps in the 40's and it worked OK.
