I've been trying to choose a boiler for nearly a week now and just when I think i've decided I've read a review which has thrown doubt in my mind, the boilers i've narrowed it down to now are Viessmann Vitodens 100W 35kw, Ideal Logic +35kw, Alpha CD35C, Worcester Greenstar 30si, Worcester Greenstar 30CDI and the Vaillant Ecotec plus 831, any help with these please cheers Gary
