Ariston Eurocombi?

I have to have the central heating on to get hot water!? I had the diverter valve changed and this hasn't helped! The bar is running at 3, and my rad's dont seem to have a place to bleed them from like usual rads! Please help to drop the pressure as the rads are starting to get very small holes in them and leak!

Dan,
Could be the expansion vessel located in the top has lost it's pressure. This means there is no room for expansion. You can recharge this with a simple car tyre style footpump.

You should be able to operate the pressure relief valve on the boiler manually,release pressure in short,brief spurts to correct level.

have you tried the back top side left or right of the radiator maybe covered with small plastic cap?
