Burner device for heating apparatus

A burner device comprising:

• an air intake;
• a burner head including an ignition device;
• a body section defining a fluid flow channel between the air intake and the burner head, said fluid flow channel being defined in a plane;
• a gas injector for injecting combustible gas into the fluid flow channel;
• a fan housing which houses a fan and includes the air intake and an air outlet in fluid communication with the fluid flow channel, the configuration being such that, in use, the fan draws air into the burner device through the air intake and supplies the drawn air to the fluid flow channel via the air outlet;
• wherein the burner head comprises a body shaped to define a mixing chamber, the mixing chamber having an inlet by which a mixture of combustible gas and air is received in use from the fluid flow channel, and an outlet by which the mixture of combustible gas and air is directed to the ignition device,
• wherein the burner head is oriented such that said mixing chamber has a fluid flow axis extending from the mixing chamber inlet to the mixing chamber outlet that is substantially perpendicular to the plane in which said fluid flow channel is defined and in which said mixture of combustible gas and air flows, in use, along the channel, and
• wherein the mixing chamber inlet comprises a wall between the fluid flow channel and the mixing chamber, a plurality of spaced apart apertures being formed in said wall.
