My Worcester Highflow 4.5 boiler is acting up and I wonder if anyone can
advise me. The hot water and the heating have gone off, but the pilot
light is still lit. I turned the ho****er temperature up higher than usual
and now have hot water again, but no heating. I've checked my radiators and
they don't have any air in them. Which components could ne causiong the
fault? How can I check they are / are not working?
In advance
Thanks
Dave
