Condensing boilers

Since 2005 all new gas fired central heating boiler installations in England and Wales have to be high efficiency condensing boilers. The same applies to oil fired boilers from 1 April 2007.

It must be noted that the return temperature of a condensing boiler must be at approx. 55 C or lower to allow the boiler to condense.

Householders are being led to believe that the A rated boiler they’re installing works at 90%+ efficiency however when they run their systems at 75 degrees plus the return temp is too high for condensing to occur. With a radiator central heating system the boiler temperatures need to be set up to 75 C to produce sufficient heat within a building. When the boiler is set at 75C it will only condense at start up which hugely diminishes its efficiency.

When a condensing boiler is not condensing it is not operating as efficiently as it is designed to.

The only solution available for a heating system and condensing boiler to operate efficiently is by installing the Oxyvent Tank as it allows the boiler temperature to be dropped from 75C+ down to 65 or 60C. This will allow the boiler to remain in condensing mode most of its operating time and will result in a significant fuel saving. All rooms will heat to the required temperature.

There is no other option available that will allow the temperature of a condensing boiler to be reduced by 20 C, while achieving greater heat transfer and efficiency.

So when installing an Oxyvent Tank with a condensing boiler the savings and efficiencies are significantly increased over a standard boiler installation.

The Oxyvent Tank prevents Thermal Shock in boilers.

Thermal Shock in conventional boilers is caused by sudden thermal changes that occur within the boiler causing rapid and uneven contractions of the boiler.

Heating designers have tried various approaches over the years to combat this problem but have been unsuccessful. Until now Thermal Shock has been accepted as a normal process within a heating system but with the unique design of The Oxyvent Tank it can now be completely eliminated.
