I installed a valliant 8 years ago, it was a combi, its the best boiler i have ever had, its never given me any problems and warms up a 3 bed with no hassle, i have hot water 24 hours too.
If you want to see which boiler/brand is recommended by non biased/independent reviews, try Which? you can join for 1 pound for a trial and if you cancel within 1 month, you pay nothing more, highly recommended.
Hope you find a boiler that suits your needs and provides you with a life long service.
