Central Heating has no vent by Hot Water Cylinder

Postby creekybones » Sat Nov 29, 2008 6:15 pm

Hi All,
The central heating system in my house is open vented with a conventional boiler. Which is fully pumped. I have replaced a couple of radiators in the past & have had trouble with airlocks while filling the system again.
I have notice I do not have a vent located by the hot water cyclinder in the coil circuit.

Do I need one of these as I also have alot of air running in the system that I can not remove.

For your info, The central heating was put in a few years after the house was built if that helps.

Thanks in advance,

Simply Build It

When I installed my own heating I included an air bleed nipple above the hot water coil. This meant that I could bleed the coil in the same way as I would with any other radiator. I have not been troubled with air in the system!

Hope that helps
