Dear all
If anyone can help, gratefully received. I have moved into a victorian 3 bedroomed semi in Kent. The radiators were all shut down for some reason, and on starting the system up, those at the bottom of the house were very cool. The system is 30 years old I believe, from the boiler handbook (1983). I have used desludger and drained the system, and balanced the radiators, with minimal effect. I have a Grundfos UPS 15-50x18 pump. In the middle is coin size disk with a grove in. Does this adjust the speed and can I turn it up (sorry to be ignorant), and if not, would changing the pump to a bigger size be my only option? The hot water is very hot, so the boiler seems fine. Many thanks to anyone who can advise.
