power flush, chemical flush or something else...?

I presume you have bled any air out of the radiator?

Yep, I've bled all the rads in the house-water comes out straight away, no air.

Did the pin move up and down loosely or does it feel 'sprung' ?? If your ex hit it with a hammer, it may have closed permanently...

Hi- it felt springy, is that a bad thing? Stupid ex, never liked parting with cash so nothing ever got done properly :-(

Well, the little pin on the trv was moving freely in and out so looks like that wasn't the problem..

The pin moving doesnt necessarily mean the valve does move up and down on its seating, it could still be stuck closed

Oh dear, the plot thickens eh? I think I'll get that plumber out to have a look and keep my fingers crossed!

Power flush should be done by a central heating professional, someone who works on gas boilers and central heating systems all the time, therefore "Gas Safe registered", it will be much better than one who just accomplished 3 hours powerflush course. My machine has a flow rate of more than double that of most power flushing pumps on the market, enabling it to remove more debris from a system and in less time.
