The Vortex Energy Saver works in a very simple way by harnessing phenomena created by the circulating pump. As the water enters the Vortex Energy Saver the action of the pump causes it to spin into a vortex. In the middle of the vortex there is a low pressure zone which is sufficient to draw the dissolved Oxygen from the solution. As the water reaches the outlet of the Vortex Energy Saver the action of the vortex increases and the bubbles of air, now out of solution, rise upwards and are collected through a dip tube to be released from the system through an air vent.

This action will reduce the dissolved Oxygen levels down to around 0.2ppm. Air bubbles in the heating system are by nature lazy and lethargic and reduce the heat transfer efficiency. As a result of removing the dissolved Oxygen down to an inert level the heating system will become more efficient in terms of energy usage, hot water regeneration and higher radiator temperatures and therefore reduce heating costs. The Vortex also helps prevent corrosion which causes the formation of magnetites.  Magnetites in turn shortens the life of radiators, pumps, boilers and valves as well as making the system work inefficiently. With no moving parts the Vortex has a life expectancy of 40+ years and should outlast all other components in your heating system.


The Vortex Energy Saver is designed and manufactured in the UK. It combines the physics of Henry’s Law and Vortex technology to remove the entrained air and dissolved Oxygen from the water in a wet central heating system. The Vortex Energy Saver is the only deaerator on the market that has proven to remove dissolved air down to an inert level resulting in substantial energy savings and helping to prevent corrosion.  The Vortex Energy Saver is now playing a large part to help combat fuel poverty as well as assisting the general population save money.

Domestic heating systems will typically contain between 1% to 2.5% entrained air.  This air in the heating system reduces the heat transfer efficiency resulting in more energy than necessary required to heat the water to the desired temperature.  Additionally, Oxygen in the entrained air is highly corrosive reducing the life of the heating system and air bubbles form causing problems such as; air locks, undesirable noise, pump cavitation etc.

dissolved oxygen
The pipes and radiators contain air bubbles that reduce the heat transfer efficiency.  The Oxygen in the air bubbles cause corrosion and the formation of magnetites in the heating system.
dissolved oxygen
With no more air bubbles from the Vortex installed, the water is able to flow freely and the heat transfer efficiency is increased. The boiler burn time is reduced and the water is free of magnetites that cause damage to the heating system.
