Heating Levers

[Jim77]

Hi all - can someone explain what the two black levers are in this picture? Are they for putting more pressure in the heating system? I have a Megaflow Eco Systemfit Unvented Cylinder.

The second one is on the right hand side (not the best picture). So when replacing a radiator I would need to use this to top up the pressure? What pressure should it be?

Yes open one fully then open the second slowly until you hear the water / pressure moving

On the pressure guage 1.2 ish is fine for a cold system eg rads cold
