I'm laying floor and skirting, and need to remove 2 radiators for access, the radiators have therm valves at one end and nipples at the other. Can I remove them without draining the whole system?

You can remove them without draining the whole system. Start by closing the valves on each end of the radiators. You now have only the water locked in the rads to drain out. If there is no drain off on the rads, you will have to slightly crack open a valve by undoing the large nut where the valve enters the rad. The right hand valve should be undone in a clockwise direction, and vice versa for the left hand valve. Have something to catch the water as it starts to dribble out, and some cloths to wipe up any spillage. When the dribble starts to lessen, then open the air vent and it will run faster. Slowly open the large nut a bit more to let more water run.. When you can't get anymore water to run out and after undoing the large nuts at both ends, then get someone to help you lift the rad off in an upward direction. As it comes away from the valves put your thumbs over the open end of the rad to prevent any dirty water that may be left in the rad. Then upend the rad to make sure no water is left inside. To replace is a reversal of these instructions. Open the valves again to refill, wait 2 minutes and vent any air from the rad. Good Luck. Don't forget to refill boiler to 1 bar.

Hi -
"the radiators have therm valves at one end and nipples at the other."
A 'nipple' (in plumbing terms!) is just a short piece of threaded metal, NOT a valve. To remove individual radiator(s) only, you must have a valve at each end. MANY years ago radiators were sometimes installed with only one valve fitted, which meant that the whole system had to be drained to remove any rad.

Turn the thermosatatic valves off with the wheel head, make sure they are off and not just frost protected, the other valves require pliers and turn clockwise to off, undo the nut from the valve to the rad at one end with a bowl under, and a bucket by your side, open the bleed screw and the water will drip into bowl, transfer to bucket when full, to stop the flow, shut the bleed screw or close the nut on the valve, when water stops, undo the nuts between valve and rads and remove rad.

From what you have mentioned, i'm guessing you have a combi boiler, wherein case i'ts a "sealed gadget". As you probable comprehend, while water heats up it expands. without someplace for that growth to pass, the strain could construction up in the pipes each and every time the gadget warms up from chilly. over the years this could harm the gadget. So, interior the boiler is a determination vessel which includes an inflatable air cushion that incorporates the growth and contraction led to by using fact the gadget heats up and cools down. under time-honored circumstances this cushion helps the gadget tension to proceed to be particularly consistent. in spite of the shown fact that, if the the two cushion fails or there is too a lot water in the gadget in the beginning, this could reason the severe tension you're experiencing. first ingredient to envision is: does the strain go up and down while the heating gadget cools down and heats up? if so, this could point out a failed growth vessel. this could would desire to be demonstrated and repaired by using a Corgi registered engineer. If, on the different hand the strain does not variety a lot because it heats up from chilly, the gadget has probable been overfilled and additionally you are able to desire to enable some water out. seek for suggestion out of your coaching manual for the main appropriate fill tension. As I mentioned, i don't comprehend what boiler you have, yet i wish the information helps besides.
