Direct Air Connection

Our expert showroom staff can talk to you about all aspects of the technology used in today’s fires.

For instance, many of Anglia’s wood-burning stoves feature a ‘Direct Air’ facility. This option enables the appliance to take in the air it uses for combustion directly from outside your home, rather than using the air which is already in the room. The benefit of this is that in most cases there is no need to incorporate additional ventilation into your room.

Regulations stipulates that hazardous levels of flue gases are not permitted to enter the installation location of the stove when the stove is in operation. The flue gases have to be drawn off via a chimney/Flue system.

In conjunction with ventilation systems, special safety precautions have to be observed, since ventilation systems can create a sub pressure that can allow the flue gas to escape into the room. In case of a malfunction, flue gases can escape via the stove’s air inlets,which are normally used for domestic combustion air supply.

The term “direct vent stove” arose as a result of these considerations.

Direct vent stoves have to meet the following criteria:

 due to their design, they have to be sealed tight enough to the installation location, so that hazardous levels of   flue gases cannot escape into the room where the stove is installed

 the stove has to be able to be operated regardless of the room size and the ventilation of the room where the

  stove is installed.

 pipes can supply the combustion air directly from the outside

At the moment there are no clear regulations in the with direct air stoves within the UK. However Europe offer us some guidance as they have long established regulations around this, as such there are two standards recognised in Europe the German DiBt and the Swiss Minergie Module. There are many stoves on the market that say they have direct air but do not meet these requirements so additional ventilation to the room would be required.

Anglia Fireplaces offer a range of product from Europe that offer these qualifications, whether it be an inset appliance from M-Design a free standing appliance from Hase, a storage stove from Tonwerk or the fire that is fascination Xeoos .
