I've been decorating and had removed a radiator to wall paper behind it. Removing the radiator had resulted in the pressur in the heating circuit to drop so I raised it to it's operating level. This was two days ago and I was happy decorating at a leisurely pace as kneeling is still uncomfortable after my bout of cellulitis.
This afternoon, my wife asked if it was normal for the pressure in the heating circuit to be at four bar as it's been like that for two days.
I spring into action and take a bucket to catch surplus water when I open the thermostatic valve in the room that being decorated. It did the job but I could totally shut down the valve afterwards and a bucket full and several large bath towels full of water later accompanied by an ingress of water in the room downstairs, I managed to decorate the bay window that houses the radiator, re-attach the radiator and step back to admire the work. It looks good.
I was so stimulated by this victory that I got a bike out of the garage and went for an exploratory pootle on it this evening. My first bike ride in three months.
I feel good.
