Radiator bleed valves

[HawkWhiteFinger]

When I fit my radiator bleed valves, is it best on the flow side, return side or doesn't matter?

Wherever is easiest to access.

As long as your rads level it shouldn't matter haha

I find in the hole is the best ...

Either end - really doesn't matter.

BUT

When I hang radiators I have a little think first. It's easier to bleed when bleed point is on the right (because I'm right handed). If this is in a corner then the other end is probably best, especially if access is easier.

Same with TRVs. Best practice to put them on flow but with 2-way trv's it doesn't really matter. Again easiest on the right but I also take into account the tiny micro climate ... they'll work better in open space as opposed to a "sheltered" corner.

If it's a combi system I fit the ABV on the left.
Open vented systems on the right.

Thermal store systems I fit one at each end.

My only exception to this rule is on warm air units, where I don't fit any at all!
