The Oxyvent Tank retails for £560 ex VAT in the UK – please contact us for trade/wholesale prices for the UK
For sales in Ireland, please contact us for current retail and trade prices
The Oxyvent Tank requires no maintenance.
The Oxyvent Tank produces results and is compatible with all water based central heating system including Gas, Oil, Solid fuel, Ground and Air Source Heat pumps, Wood Pellet, Sealed and open vented systems, Condensing boilers, Combi boilers, Underfloor heating and radiators.

• Increases the heat and efficiency of your central heating system by creating radiant heat rather than standard circulating heat
• 30% – 50% fuel savings
• Increases condensing efficiencies in modern condensing boilers
• Eradicates the need to balance your system or bleed radiators
• Eliminates problems associated with Thermal Shock
• Reduces maintenance and long term damage to your system

This will vary dependant on the size of the property, how well insulated it is and how warm you like to keep your house. From the installations to date we expect the System to pay for itself within 3-4 years.

The Oxyvent System was invented and patented by plumber Tim Cremin to improve the performance and efficiencies of all heating systems. Based in Ireland the product was launched into the Irish Market in 2002
To date we have installed thousands in Ireland. In January 2011 we are completing the first installations in the UK..
Trinity College Dublin undertook a series of tests to assess the Oxyvent System claims. Click here for further information on the tests.
Oxyvent has a TUV certification of design, ISO 9001/14001, TS 16949, holds a Certificate of Excellence from the International Exhibition of Invention, Geneva and holds International patents.
The Oxyvent Tank is manufactured by the VDL Group in the Netherlands.

You will need a qualified heating engineer to install the Oxyvent system. No specialist training for the plumber is required.
Although systems will vary, from our experience to date, the Oxyvent system takes around a day to install.
See how it works
The Oxyvent System is an addition to any existing or new heating system making it simple to install for professional plumbers.
The results will be seen immediately.
Just follow the standard heating and installations guide lines.
It is virtually impossible to combine boilers and get them to function properly without the use of the Oxyvent System as it allows each boiler to operate independently. In conventional dual boiler systems e.g. two gas boilers, one boiler always seems to overpower the other, when the demand for heat is called. This is caused by an uneven flow rate through the boilers. The Oxyvent System evenly balances the flow rate and temperature of each boiler, allowing the boilers to operate simultaneously to heat the system rapidly.
Removing air is only one of the functions which the Oxyvent System achieves, other products on the market do not increase the flow rate, blend water temperatures, prevent pump cavitation, remove thermal shock, save significant amounts of fuel etc.

The Oxyvent system is designed to address fundamental design issues with all water based heating systems. It is in no way a reflection on your plumber or other products on the system that the addition of an Oxyvent Tank improves the overall performance of your system.

Of course there are examples of poorly manufactured or installed Central Heating systems however the best plumbers working with the most well built and designed equipment still see benefits with the addition of the Oxyvent System.

The majority of plumbers are highly qualified and experienced professionals who take pride in their work and will be disappointed if there are problems found with their work.

In a nutshell a well designed system will operate with a low (AT) differential between the inlet and outlet valves on your radiators. A ‘well designed’ quality system will still be operating with a differential of over 10 degrees between the two valves, only the addition of an Oxyvent System will reduce this to around 2 degrees.

The tests on the Oxyvent System were carried out at Trinity college in two ‘perfect’ installations and the results still highlighted the benefits of the Oxyvent System over conventional heating systems click to see the product tests

When you fire up the boiler in your newly designed, state of the art conventional system air will be formed in the system as the water heats. The pump will begin to cavitate resulting in a poor flow throughout the system – neither of these problems are a result of poor installation of the system.

The current system suffers from a low thermal output and the large scale temperature fluctuations inherent in conventional systems.
Heating engineers are limited to what they can offer in an existing conventional system as they can only make sure that the proper installation is carried out to the required standards.

The required standards unfortunately do not and cannot prevent the common problems associated to conventional systems without the addition of an Oxyvent System.

With conventional systems radiators create convection currents which result in the hottest part of the room being the ceiling and the coldest the floor. With the Oxyvent System in place the heat radiates considerably creating a better overall heat dissipation throughout the room.
Normally when people check their radiators they only place their hands along the top of the radiator. This is not the proper way to check for heat and it can be totally misleading about the performance of your radiator. You must check the complete radiator especially the centre lower section – all of the radiator must be of a uniform heat to ensure optimum efficiency.
In a conventional heating system the radiators nearest the boiler will naturally heat more than those further down the line. What your plumber will do is balance your system to ensure that radiators further away gain the same temperature as those closer. With the Oxyvent Tank installed this balancing is no longer necessary
When water is heated above 60 C air bubbles are formed. This process takes place within the boiler as part of the natural process of heating water.
