Great news! The boiler is fixed. Now I know what it feels like to come home to a warm, quiet flat. It is so cozy in here.
So, what was the problem? It appears that our techs drilled the hole for the pipes from outside to inside – with the pipes already in installed. This means that a thick gunky mess developed in the pipes as the brick powder collected. I need to believe that it was their effort to ensure that our flat not get too dusty. But, the repair men this time around told us that the gunk was inside too – all over the pump.
Now it is fixed and we are so happy. At 6.30am the heat starts and the bedroom warms up. What a concept!
