No more bleeding of radiators
The Oxyvent Tank when installed brings about dramatic change.
The Oxyvent Tank increases the flow of water through all radiators (33% min.)
This increase in flow rate results in differential between top and bottom of radiator
being as little as 1 degree.
Your radiator is now emitting radiant heat rather than the old convection heat.
It is a different type of heat much more intense and rooms maintain
the heat for longer.

After installation of The Oxyvent Tank
The result of all this is a more uniform heat between ceiling and floor level
(not unlike underfloor heating systems).
Radiant heat creates an environment where the human body
feels vastly more comfortable in a shorter space of time than heretofore.
Room thermostats and thermostatic valves can be set lower,
yet your comfort level is higher.
Obviously this results in huge fuel savings for the householder.
The Radiator
The radiator was invented in 1855 by Franz Sangalli and people all over the world are still having to use vent keys to get the air out of radiators. Frequent bleeding of radiators is a chore in most households. The air causes corrosion within the radiator resulting in a build up of silt in the centre lower section of the radiator, requiring the system to be flushed out. This involves the need to remove the radiator and clean it out which can be very hideous for both the householder and Heating contractor.
The air is formed in the boiler when water temperatures exceeds 60°C / 140°F. Due to the unique patented design of the Oxyvent tank it captures the air when it leaves the boiler and releases it automatically when the system shuts down. distributing air free balanced temperature water throughout the heating system with a 33% increase in flow rate, resulting in all radiators heating evenly throughout the building and increased temperature in all rooms.
The type of heat produced by a radiator is known as convection heat transfer. The hot air forms air currents, rising up towards the ceiling and as it cools it drops towards the floor to be re-heated, leaving the hot air accumulate below the ceiling. The lower section of the room is cooler as the chilling air currents return to the bottom of the radiator to be reheated, keeping your body, especially your feet cooler and you find yourself leaving the heating on for longer periods.
With the Oxyvent Tank installed a dramatic change has taken place. The entire radiator heat at an equilibrium temperature creating a Blackbody, which gives out radiant heat. The heat travels in Electromagnetic waves travelling outwards and downwards from the radiator, heating the air close to the floor. Your body easily absorbs radiant heat, and you feel more comfortable at lower temperatures.
How to check if your radiators are heating properly:
Check the lower centre section of the radiator, It should be almost the same temperature as the top. All radiators should heat at equal temperature throughout the building.

Balancing The System
We are all familiar with closing down radiator valves at the start of a heating system to maximise heat gain from radiators further down the system.
This is done with almost every heating system, it is known as balancing the system to allow the heated water be distributed evenly among all the radiators in an attempt to get even heating throughout. There is no set rule for balancing, it is trial and error and totally up to the individual, and is accepted as normal practice with heating systems.
• The heat differential between the top and bottom of the radiator is 11°C this is classed as an excellent system and every heating engineer worldwide strides to achieve this by balancing the system.
• With the Oxyvent Tank installed the heat differential between the top and the bottom of a radiator is only 1°C to 2°C and no balancing required.
Balancing of systems restricts the flow rate and reduces the water temperature returning to the boiler. The boiler then operates for longer periods, wasting fuel.
The principle behind any heating system is to move water fast, not slow it down. The Oxyvent Tank balances all heating systems automatically, allows all radiator valves to be fully opened, distributing equal heat to all radiators at a higher temperature and with 33% greater efficiency.
Frequently asked questions
Q.
I need to bleed my radiators regularly, where does this air come from?
A.
The air is formed in the boiler as oxygen burns off at temperatures over 60°C. The air released by this process has no option but to travel from the boiler into the radiators. The Oxyvent Tank captures the air and release it automatically, not allowing it to enter the radiators. It eliminates the need to bleed radiators.
Q.
All my radiators are not heating properly and some radiators are much cooler than others?
A.
With The Oxyvent Tank installed all radiators will heat at an even temperature from top to bottom.
Q.
Can The Oxyvent Tank be installed in an existing heating system?
A.
Yes. The Oxyvent Tank can be easily installed in existing systems. It is normally installed in the hot press or near the boiler.
Q.
Will The Oxyvent Tank eliminate radiators at the end of the line not heating?
A.
Yes. All radiators will heat at an even temperature.
Q.
Is The Oxyvent Tank maintenance free?
A.
Yes. The Oxyvent Tank is maintenance free.
Q.
Has The Oxyvent Tank been tested and proven?
A.
Yes. The Oxyvent Tank has been tested by Independent companies. It is installed in homes throughout the country for the last six years with amazing results. It has been tested in laboratory conditions, but more importantly it has been tested and proven in real life situations.
Blackbody
A blackbody is defined as an object that can absorb and emits radiation heat with complete efficiency. The higher the object's temperature, the higher the frequency of the radiation it gives off.
Experts have said that there is no perfect blackbody radiator in nature, but it is possible to construct one by producing an even heat throughout a radiator, allowing the radiator to produce radiant heat. This is what Oxyvent has achieved.
Kirchhoff's law also correlates mathematically the heat radiation properties of materials
at thermal equilibrium.
