Hi.
I've searched the threads and haven't found any similar topics so I'll try to be as brief and thorough as possible.
I'm in a 4 bed semi-d for last few years with extension to kitchen. The extension has 3 rads in it. Only one is working and leaves the kitchen and extension very cold.
I started with bleeding the rads and the water went through but they cooled quickly again. I then turned off every other radiator in the house and the 2 heated very quickly and fully.
I've heard the term balancing, but as soon as I turn on a single other radiator these 2 loose heat and go cold. My heater pressure is around the 2 mark. Normal operating is indicated as between 1.5 and 2.5 so pressure is fine. Any help would be greatly appreciated,
Blake
