    I have a Baxi platinum combi 33HE with a weather compensator fitted and don't fully understand the using of it. I understand the way in which it works but not sure on which 'Curve' to set it on via the Central Heating Control knob. The numbers on the curve: 10, 15, 20, 25, 30, do they represent...

    No hot water in hot weather

    On very warm days (25 degrees plus) the hot water runs out very quickly. It doesn't run cold it just runs out. Nothing comes out the taps and there is no water for the shower to pump.The next day it is fine and is fine at all other times. Could the hot weather be an issue or is it just coincidence?
