Post Installation

Physical things to look out for post installation of Airgon.

The automatic airvent hissing occasionally as air is released. This is a continuous process – as air is introduced into the system water, Airgon will remove it.

The pressure drops in your system.  Air and dissolved gasses take up space so when air is removed it leaves a void, this is remedied by simply topping up the system and it will normalise.

Temperature rise – radiators seem hotter, with no air or dissolved gasses in the system water cold spots and air locks are removed.  Removing the thermal barrier caused by nitrogen means more heat is released into the room for less heating fuel consumed.

No more noise from radiators, the boiler or the pipes.  This is called cavitation and is trapped air similar to the example of air being released in boiling pan of water.  Without air and gasses in the system water, the system will become quieter as well as more efficient.

Under floor heating (UFH) and end of line radiators.   Because of the diameter or bore size of UFH pipes, air can easily become trapped and nitrogen can line the pipes creating a thermal barrier.  End of line radiators are usually the furthest away from the boiler so prone to lower temperature output.  These will usually start working better post installation and you just need to adjust the thermostat and save money.
