Underfloor heating

To explain how this works we will compare an underfloor heating system pre Oxyvent Tank installation and post Oxyvent Tank installation

Pre Oxyvent Tank

1. Experts recommend underfloor heating systems must be constantly on or constantly off.

2. Even the very best of systems have not got uniform heat throughout the floor.

3. Patchy heat even at very high thermostatic levels.

4. Cracks in floors.

5. Due to presence of air, the system needs to be flushed out every 2 years at a minimum.

6. Poor movement of water through underfloor pipes due to air build up in system.

7. Heat up process takes approx. 2 to 3 days to reach maximum potential.

8. Resulting in huge fuel wastage due to above inefficiencies.

Post Oxyvent Tank

1. Heating system does not have to be constantly on (heat recovery on the floor is rapid).

2. Uniform heat guaranteed throughout the building in all rooms.

3. Even heat at much lower thermostatic levels and noticeable increase in speed in which it is achieved.

4. Heating system will not cause cracks as the floor will heat uniformly.

5. No need to flush out the system.

6. 70% increase in movement of water through underfloor heating pipes.

7. Heat up process time greatly reduced.

8. 50% fuel saving due to efficiency of system.

How to check if your underfloor heating is operating properly

Have a look at the underfloor heating manifold. There should be a little glass flow meter attached to most systems, usually reading up to 4 or 5 litres as shown on diagrams above.

This shows how much water is passing through each loop of pipe buried under your floor. These flow meters are also used for balancing the system; meaning that the loop that shows higher flow rate can be cut back to maximise heat gain from other loops further down the system. You can count yourself lucky if you have 1.5 litres per minute in all loops.

As you can see in diagram 2 after installing The Oxyvent Tanks, all flow meters will read 3.5 litres. This is testimony as to why it is essential to include The Oxyvent Tank in all underfloor heating systems.

Flushing the air out of the system

With a radiator you can bleed with a vent key to get the air out; under floor heating must be flushed out by a professional regularly to release the trapped air. This is a process where all the water must be flushed out of the pipes under the floor and refilled with fresh water.

Flushing the trapped air out of the underfloor heating is a regular occurrence for some systems as the efficiency of the system will deteriorate unless the air is flushed out. This is time wasting and costly.

The Oxyvent Tank eliminates the need to flush the air out of the underfloor system as it captures the air and releases it automatically before it gets into the underfloor heating pipes.

It does not make sense to install underfloor heating without the Oxyvent system. In a new installation it can pay for itself in less than one year.
For most underfloor systems two Oxyvent tanks are required. If you require further information, please contact Oxyvent.
