Why is it radiators upstairs need bleeding more than those on the ground floor?

Answer 1

This is because air in the system will collect at the highest point. If you have to bleed them often, then you are not getting all the air out the first time.What you should do, is to turn off the boiler, and leave it for10 minutes. Then vent all the radiators upstairs, and when water starts to come out of the bleed valve, let it run for about 30 seconds. close valve Check water pressure on boiler, and vent the other rads the same way making sure you check water pressure after venting each radiator. This should solve the problem. You have most probably vented all the rads upstairs and after you have had to fill water in boiler to the right pressure. In doing theat. you are putting air back into the system because the water pressure was allowed to go too low.

Answer 2

you pick to stability them first commence upstairs with the furthest one The Radiator must have a thermostat valve and a regulator valve with a lock preserve- Take the lock preserve off insert a screwdriver and close it off them open it a 1/2 turn do the subsequent one an finished turn etc - What you're doing is forcing the nice and cozy water to flow down stairs

Answer 3

Although air can be trapped anywhere in a system, it gathers at the highest point due to being lighter than the liquid it is in.

The real question would be where do air bubbles go in liquid hydrogen. LOL

Answer 4

Air rises

Answer 5

Dozen reasons but the obvious is that air rises to the highest point..

Answer 6

For the simple reason that air rises

Answer 7

simple, because water weighs more than air, the air in system goes to the highest point ,,,,,upstairs

Answer 8

because air rises in the systom

Answer 9
