I recently drained my system and filled it with "desludger", with a view to running it for a week then redraining and filling with inhibitor. I turned down the boiler teperature control to force the water through the radiators at a lowish temperature (it being summer). However, the temperature seems awfully high, even with the boiler temp. control set to minumum. Can anyone advise whether i am misunderstanding, or do I have a fault?

Thanks
