This pioneering new tank will even resolve common domestic heating problems reducing maintenance costs in any of the 22 million homes in the UK with a water-based heating system – new or old.
Paul Worswick, Oxyvent Director, said: “Rising fuel prices mean people want ways to cut heating bills and maximise the benefit they get from the heating they do pay for.”
“With carbon emission reductions taking centre stage and rising living costs leaving little spare cash to fix heating problems when they arise, the Oxyvent tank addresses all of these problems in one neat little affordable tank.”
What does the Oxyvent tank do?
• It forces radiators to radiate more of their heat out into the centre of a room so homeowners get the benefit of the heat, not the walls or ceilings as happens with conventional systems.
• It enforces boiler temperatures to be set at a low 60 degrees (65 degrees when heating water) so heating uses much less fuel, reducing carbon emissions and the cost of heating bills.
• It increases the efficiency of condensing boilers as the cooler water running through the system means the boiler will be in condensing mode much more of the time, saving more fuel and money.
• It makes hot water flow around the central heating system much faster which fixes problems such as odd radiators in a home that don’t work or radiators with cold areas.
• It takes the air out of a central heating system so there is no need to bleed radiators and it also radically reduces corrosion in the radiators, reducing the build up of sludge leading to the need for power flushing.
How much energy and money does it save?
Following thousands of installs in Ireland, where the Oxyvent patented technology was invented, testing by Trinity College Dublin found that people felt 30% more comfortable in a room heated by a boiler with an Oxyvent tank installed set to 63 degrees than when the boiler was set to 74 degrees without Oxyvent. Considering most UK boilers are set at much higher temperatures, this equates to a considerable money saving.
Taking an energy bill of £1200, £684 of this goes on heating space in your home (57% according to DECC energy trends 2009). With energy providers announcing price rises of up to 18%, homeowners could see this rise to £807. Installs to date show the Oxyvent could save up to 30% on energy bills, so a house with an Oxyvent tank installed would see the central heating portion of their bill drop to £565. That’s an overall saving of £242 which means the heating bill after Oxyvent is installed is still lower than it was before the price rises are taken into consideration.
Homeowners who have installed an Oxyvent tank feel so much warmer, they also turn their thermostat temperatures down. The Energy Saving Trust says that reducing your thermostat by just one degree could save the average home £70/year or 10% off your heating bill. Combined with the savings from lower boiler temperature settings, increased efficiencies from condensing boilers operating in condensing mode more of the time and fewer maintenance costs, the savings with Oxyvent will be much greater.

FACTFILE:
Common central heating problems are caused by the poor slow flow of water, heated by the boiler, travelling around the system. This is caused by resistance that exists in central heating systems, caused by air getting in and the water being pumped through one big circuit from the boiler to the hot water tank to the radiators each time it is reheated.
When an Oxyvent tank is installed, it significantly reduces this resistance by taking air out the system and removing the boiler and hot water cylinder from the heating circuit. This reduced resistance means water can travel around the system three times faster. The faster the water travels, the faster and more evenly radiators heat up.
This more even heat means radiators will give out much more radiant heat which makes people feel warmer than standard convection. If you imagine standing in the shade and then the sun on a hot day, the principle is the same. The air temperature won’t change in the sun but because the sun is radiating directly on to you, you feel warmer.
This more effective radiant heating means you don’t need the water in your system to be as hot so you can set a boiler’s temperature to a lower 60 degrees (65 degrees when heating water). As most boilers are set to 70 degrees and above, this is where homeowners save money. As many homeowners say they also turn their thermostat temperatures down, the savings will be even greater.
How does it save more money with a condensing boiler?
It’s well known that condensing boilers only condense when the return temperature of water to the boiler is 55 degrees or below. In reality, if the boiler temperature is set too high condensing only occurs when the heating fires up but stops when the water returning from the radiator goes above 55 degrees. With an Oxyvent Tank installed, the cooler boiler temperature of 60 degrees (65 degrees for heating water) means a condensing boiler is set at a much lower temperature. The return water will be 55 degrees or below far more of the time so a boiler will operate in condensing mode a great deal more of the time and achieve its high efficiency rating.
Oxyvent has been tested by Trinity College Dublin’s Department of Mechanical & Manufacturing Engineering, Fluids & Heat Transfer Laboratory. The study can be provided upon request and test conclusions are available to view at www.oxyvent.com.
