Our boiler at home today decided to display a “F22 0.2” message, at the same time I noticed it also had a low water pressure. Which I suspect was caused by myself bleeding the radiators of air the previous night, thus reducing the overall pressure.
After sometime search the web.. I found a common solution… thanks google
The solution was to open the filling loop until the boiler pressure and hey presto problem solved and I didn’t have to call the gas man and look like a silly bugger. Yeh… it seems easy in hindsight but at the time I had not a clue.
