So you have had the tops of and moved the pin up an down using pliers?

Easiest solution is to check the simple stuff first, unscrew the TRV and make sure the pin underneath moves freely, you want it in the up position (needle pliers are ideal for this) if this is OK check the other side and undo the valve slightly to increase the flow.

Take care when pulling the pin plunger up with pliers. I once pulled a pin right out of a cheap (Wickes) TRV. That was quite an, er, interesting experience. Probably much less likely with a decent, e.g. Danfoss one.

I love bleeding radiators with my bleeding radiators key... the thrill of the first sudden splurge of water as the air escapes and the panic to shut the little valve... bliss!

Ok what’s the small valve that adjusts ? Could that be used to balance the hot water for the CH between upstairs and downstairs ?
