Hi,

We moved into our 30 year old house in January. The pipe entering the 
radiator in the lounge makes ticking noises when the heating is on, I guess 
in tandem with the central heating pump running. The ticks are 1-2 a second 
and it lasts for up to a couple of minutes. Really irriatating, as you can 
hear it throughout the room.

Four months' back I also had a combi boiler fitted, and the pipes in the 
room next door to the boiler also make the same kind of ticking noise. Again 
same frequency and duration. In this case I think it may be that there's 
some expanding foam around the pipes, that may be making the noise (your 
thoughts?) but again, you ca hear it clear and loud.

What can be causing this? and what can I do to stop it?

Sounds like normal expansion of the metal as it heats up.

Yes, the movement of the metal (pipe) in contact with something
stationary, gripping then slipping and pinging/ticking. Try removing any
tight contact points between pipes & floorboards/joists. The usual trick for
under floor is to place some thin insulation around the pipe as it passes
across a joist.

read it.

This is usually due to the notches in the joists not cut deep enough. When
the floor boards or chipboard has been replaced...they are touching the
pipework.

Might be worth dusting the areas with talcum powder as lubicant.
