When we got back from our holiday in Qatar we discovered that our boiler had stopped working. Since Douglas' stroke I have learnt what to do, so promptly got the screw driver and went to work on the boiler upstairs. The result: hot water and a warm house.
Having had the drama with the boiler, I decided to keep checking that everything was on track but soon discovered all was not well as the pressure kept going up and once it reached 3.0 bars the downstairs unit would flash a warning. I had learnt, during the Summer when the house heating was not activated, that this only happened when the house heating was activated as the pressure decreased when the water heating was activated. The result: switch off the house heating and fill the bath. The pressure then decreased and one could activate the house heating once more.
This became rather tedious so we called an engineer who discovered that I had not tightened the screw upstairs enough when I had initially sorted out the heating problem. The result: he tightened the screw and bled the system so lowering the pressure. Success? Not.......
As a safety feature the system tries to lower the pressure and it is now stuck in that mode so with the pressure low, every time we activate the system it lowers it even more. The result: this morning when I came downstairs, the red light was flashing and we had no heating.
I was in panic mode as the weather forecast is snow for this weekend. As soon as Douglas woke up I got him to use the screw driver upstairs as I do not have the strength to tighten the screw once the pressure is back to 1.4 bars. The result: all is working well once more. we have hot water and a warm house.
Just checked again and the pressure is 2.2 bars. Maybe Douglas also does not have sufficient strength to tighten the screw. We will see what happens after his shower........
