Hot Water

Wouldn’t it be great if when you turned on your heating system, the first thing that heated up was your Hot Water Cylinder! Well that’s exactly what happens with Oxyvent.

Oxyvent’s unique patented design brings heated water from the boiler, straight to the hot water cylinder first and then moves on to heat the radiators. In fact the Oxyvent system is the only hot water system available that gives 100% priority to the hot water cylinder.

Oxyvent’s super efficient heat transfer rate is two times higher than that of your existing system. This allows you to operate both the hot water and central heating at the same time, and still have plenty of hot water. This can be a major advantage for large families or for bed and breakfasts, where both heating and hot water is required over a short period of time.

Oxyvent can heat the hot water cylinder uniformly from top to bottom, giving extra hot water.

Why is your hot water slow to heat up?

In the installation of most domestic heating systems it’s normal practice for plumbers to fit a valve on the pipe going to the hot water cylinder (commonly known as a Balancing valve). This is used to regulate the flow of water to heat the cylinder. Due to a design flaw in the system, that valve is usually closed down to a minimum to give a better flow rate to the radiators and taking heat longer to fully circulate through your hot water cylinder.

If you find that you’re waiting longer for your Hot water Cylinder to heat up and the bottom of your cylinder is cool – then you need Oxyvent.

Oxyvent advantages over existing hot water systems

• Patented piping design which gives hot water cylinder priority
• Heats the cylinder evenly at the same time
• Guaranteed hot water every time

What our customers have to say

  • “We built a new house in 2004 and were very disappointed with the heat from the radiators. We have a bungalow and especially the two bedrooms at the back of the house were freezing, and in the winter we had to use electric heaters in those rooms to heat them. We had the heating on all day and the house was still cold. We heard about Oxyvent spoke with them about how the Oxyvent Tank would help us. We fitted the Oxyvent Tank in 2006 and could not believe the change. All the rooms heated up fast and the boiler had to be switched off after one hour as the house was roasting. Our fuel bills are down about 30% but the best result is the house is nice and warm. We could never fill a bath with hot water before and had to do with filling it halfway, and now we can have a nice full hot bath of water for the first time.

    A lot of our friends and family have the Oxyvent Tank in their homes and they are delighted with it. We would highly recommend to anyone whether they have an old house or new one.”

    Pat & Joan Looney, Co. Kerry

  • “We have the Oxyvent Tank for about ten years, before installing it we had radiators not heating all the way through, they were cold at the bottom throughout the house, even though they were cold we were burning quite a lot of oil, so we decided to have the Oxyvent Tank installed, the difference was amazing we had even heat throughout the house all of the radiators were heating and we were burning less oil, a saving of 30 to 35% I would say, so getting the Oxyvent Tank was a great idea still today 10 years later it is working as well as it did when it was first installed.”

    Sarah Stafford, Co. Kerry

  • “We are so delighted with the Oxyvent Tank since we got it installed in 2005. We have mighty heat from the radiators, and they are hot all over, different than before. Everyone that comes in remarks on the heat and are amazed when they see how low the boiler temperature is set. Prior to putting it in I would have the boiler temperature set high, it is now set to minimum. The Hot water in the tap is now boiling, a big difference from before. I had big savings in my oil bills over the years and I would like to wish you every success with the Oxyvent tank. IT’S A WONDERFUL PRODUCT!”

    Margaret, Tralee, Co. Kerry

  • “I installed the Oxyvent Tank in my oil fired heating system in 2008. Prior to installation I had a lot of trouble with air locks in my system. The Oxyvent Tank rectified this problem.

    Since installation my yearly oil consumption is significantly lower and thankfully my heating is a lot more efficient. I would confidently recommend this product without any hesitation.”

    Tom Browne, Co. Limerick

  • “We have a sizeable heating system which consists of 24 radiators ,we always seem to have a problem getting the heat to perhaps 5 radiators. At first we thought it maybe that our boiler was not sufficient enough to run the system, but we were reassured that the output of our boiler was more than enough to run the installation.

    We tried a more powerful circulating pump but this did not improve the situation. We heard of Oxyvent through a friend and requested an inspection. He explained what the problems were and recommended that we install the Oxyvent Tank.

    We could say the results were instant, we had on the first day pretty much all the radiators heating up to what they should be, from then on the system seem to improve and it definitely now is heating to its full potential.”

How often were you given the same suggestions to fix radiators in rooms that don’t heat: Check for air in the system, Fit a larger pump, Check the water pressure, Check if the radiator valves are stuck, etc etc

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?

People normally place their hand on the top section of the radiator to find out if their heating is operating properly. This is not the correct way to find out if your radiators are functioning efficiently.
