Earlier today some idiot with a digger cut a power line and all of the power in the area went off (including our tropical fish tank - argh!) and alarm systems went into overdrive driving us crazy all afternoon. The power eventually came back on but now we cannot get our central heating to work. We have an Ideal Mini C28. Anyone got any ideas what we need to do? Can't afford a plumber/electrician call out (and don't see why we should as we didn't cause it!)
