Our new valliant ecotex plus boiler was put in on 5.11.09 and worked fine for 3 weeks but now just turns itself off at about 50degrees. The radiaitors are luke warm and the wtaer is just warmish. The pump has been replaced and the installer does not seem to know what to do. We are fed up and cold . Help.

sounds like it may be a faulty circuit board, but give vaillant a call since the boiler is new, you should be covered under warranty for faulty components so long as it's been installed correctly.
