Yes the pump works fine, all the rads are hot.

There are 2 tanks in the loft, one for the cylinder and one for the heating, both are full and no blockages

Hi,

The pump is bolted to the boiler in the kitchen directly below the tank.

No stat on the cylinder only on the boiler

No 3 port valve either, the water is heated all the time the radiators are.

Of the 2 pipes that go into the cylinder (coil pipes) one is V hot, the other is just warm

I have an old old boiler in my kitchen which heats the radiators and at the same time heats the water in a tank upstairs...
