Who doesn’t love the idea of walking on a nice warm floor first thing in the morning? Sounds cosy… but the thing is, one of biggest complaints householders have about Underfloor Heating is that it takes too long to actually heat up! Well if you want to easily cut that time in half and make your system more efficient, the answer is Oxyvent.
How does Under Floor Heating (UFH) work?
Underfloor heating works by driving the heated water from the boiler through pipes under the floor, a bit like a giant radiator. Where problems usually arise is with the mechanisms used to control the temperature of the water entering the floor. You see the majority of under floor heating systems use a fixed temperature setting of 50°C or higher. So for example, let’s say the starting temperature of the floor is 10°C and the water entering the floor is 50°C, this creates a differential of up to 40°C. But for a comfortable room temperature the floor only needs to reach 30°C – so you have to ask the question … why is a fixed temperature setting of 50°C used?
Oxyvent has shown that the higher the difference in temperatures, the slower the concrete will heat up. This leads to hot and cold patches on the floor, as the concrete rejects high temperatures. It also means that the boiler stays operating for longer, as the water returning from the Under Floor Heating is obviously cooler, therefore it keeps producing more heat than what is really needed. This is where the advantage of Oxyvent comes in.
The science behind heating a concrete floor
The natural way to heat concrete is with low water temperatures. When concrete absorbs heat at a lower temperature, the floor actually heats up 50% faster than a system heated with high water temperatures. This provides a warmer and more comfortable heat which radiates throughout the house. And since you need to be able to comfortably walk on it, it doesn’t have to be heated to more than 30°C, which makes it more energy efficient.
The Oxyvent way
Oxyvent uses a self-regulating temperature technique to heat the floor, which not only helps maintain an even temperature over the whole floor surface, but it also prevents any overheating. This is done by using a Low temperature under floor heating system that operates in a two stage process, requiring two Oxyvent Tanks in series. The first tank ensures the water entering the floor system starts off at approximately 10°C higher than the floor itself, helping to transfer the heat up to 50% faster. The second tank operates at a high temperature and raises the temperature of the returning water in the pipes before it gets back to the boiler. This keeps the water temperature high and means the actual operating time for the boiler is reduced.
One of the main purposes of the Oxyvent tanks is to increase the flow of water through your heating system. With under floor heating, the flow of water through each loop is increased from the average 1.5 litres per minute to 3.5 litres per minute. By moving the heated water through the pipes faster, it gives a more even floor temperature, prevents hot and cold patches, blockages, slow heating times and high fuel bills.
Trapped Air in Underfloor Heating
When air gets trapped in radiators it can be released with a Bleed/Vent key.
Underfloor Heating is a completely different story. To release the trapped air, you’ll need your plumber to flush out your entire under floor heating system…and that can be a costly job! The presence of air in under floor heating greatly obstructs the whole process, restricting the natural flow of water through the floor, resulting in rooms not heating and high fuel bills.
Oxyvent’s unique system eliminates air from getting into your under floor heating loops in the first place. This makes sure you have a much more efficient system that will save you thousands on maintenance costs and fuel bills.
Oxyvent customers operate their under floor heating like radiators, meaning that they turn it on in the morning and again in the evening for a few hours each time. As the heat up time is so fast, there is no need to operate it 24/7.
Advantages of Oxyvent with Underfloor Heating
- No more hot and cold patches on the floor.
- Even temperatures throughout the house.
- Easier control over the room temperature.
- It prevents air from entering the under floor pipes.
- Oxyvent has the only under floor heating system that can be operated with solid fuel on an open vented system.

Frequently Asked Questions
Oxyvent’s self-regulating temperature control system increases the flow rates from 1.5LPM to 3.5LPM which absorbs the heat 50% faster.
Yes you can. Both systems require different temperatures and share the same water from the boiler, Oxyvent has achieved this by using two Oxyvent Tanks. One Tank is used for the higher temperature radiator water and the other is used for the low temperature underfloor heating water. Oxyvent is the only system that separate the underfloor heating from the radiators successfully and efficiently.
Oxyvent has the only system that will eliminate air from getting into your underfloor heating loops. Saving you thousands on fuel bills and maintenance.
Hot and cold spots on the floor is caused by high temperature water in the underfloor heating loops. This leads to air in the loops and slow flow rates resulting in patchy heating.
Oxyvent low temperature Underfloor Heating system will give you even temperatures throughout the floors.
Oxyvent low temperature underfloor heating system heats up 50% faster. People with the Oxyvent system use their UFH like radiators. As the heat up time is so fast there is no need to have it on constantly. Saving energy whilst increasing your comfort.
This is caused by poor water circulation. Trapped air in the system combined with high water temperatures. Oxyvent can fix this for you.
When using Oil or Gas experts recommend to leave the heating on constantly, as the heat up time is basically too slow to heat rooms properly when bringing the temperature up from a lower level. This is wasting fuel by basically heating a house when it may be unoccupied during the day or when you are asleep and do not need the heating on.
With the Oxyvent System our customers use their underfloor heating like radiators. They just switch it on when they require heat as the heat up time is rapid. We have customers that has the Oxyvent System operating in their homes with the last 19 years. These customer can verify that their underfloor heating never air locked, no hot and cold patches on the floor, has saved thousands of euro in fuel and never required maintenance.
Oxyvent is perfect for linking solid fuel with underfloor heating. The solid fuels low temperature water is ideally suited to heat a concrete floor. Oxyvent underfloor heating system can be operated on an open vented system, meaning the system is fed from a tank in the attic. No pressure on the system and less maintenance.
Oxyvent has designed a unique wiring board specifically suited to solid fuel system.

Where Underfloor Heating is installed with a gas or oil boiler, hot and cold patches on the floor are quite common. It can get very uncomfortable when the floor overheats. What can we do about it?
