I have a Danfoss Air source boiler. It has two small expansion vessels, one white one red. I believe its a 3 bar system, but the red tank is currently on .5 bar and the white tank has become very heavy as if it is full of water.
This happened before when it was a council flat and they sent someone round to do something with all the heavy white cylinders.
Is this a DIY job? Can I fix the current cylinder, or does it need replacing, and how much would it cost for a plumber to do it?
