Strange Noises...

Hi There, Newbie here. Sorry for the vague title, but i am getting some strange noises from my CH and HW system. Ishall start with the heating:

The bedroom rad clicks for a short while when the heating comes on. I have only really noticed this when the heating comes on at night and wakes the missus up, who then wakes me up. Turn the rad off, and it stops.

Suggestions welcome....

Now for the fun one, the HW. If i leave the bedroom rad open while the HW is on, all of the rads heat up. If i close it, none of the rads heat up, and it just does the HW. The tri state valve (think thats what its called) is on the HW. Secondly, i get a gurggling sound from the boiler when the HW is on. This can carry on after the pump has stopped. I have managed to cure it slightly by changing the timer so that the HW and CH aren't on at the same time, and by turning the B/R rad off when the HW is on and back on again for the heating.

Again suggestions welcome...

As far as i can tell i have a run of the mill system, with nothing out of the ordinary, (or is there )....

Thanks ini advance...

That might be the radiator expanding as it warms, and moving on it's mounting brackets.
There are often U-shaped plastic spacers on the brackets that are supposed to allow the radiator to slide quietly, but they sometimes go missing.

Had an old 8 foot long X 18" rad in a bedroom once. Sounded like a double decker bus making a 3 point turn in the wardrobe when the system fired up in the morning. Never needed an alarm clock though.

So you've now invested in an alarm clock!!!!!

Thanks for the comments guys. I shall check the pipes to see if they are tight against the floor boards, Might invest in some of those rubber things, have seen them before (not on rad currently)

Any suggestions on the gurgling?
