Abstract
An intermittently operated heater has its outlet (1) connected to a chimney (4) by a chamber (2) with a flap (21) inside. This flap is kept in a lowered position by a piston and cylinder as long as fuel is being pumped to the burner. When the pump stops, the flap swings up, assisted by a fan (9) below. This prevents heat escaping from the heater to the outside. At the same time, the fan continues to operate, and air is blown through the chimney, fed from below the fan and motor (10). This prevents corrosion of the chimney. The fan is stopped by a timing device after a suitable period. As soon as the pump starts, the flap again is swung down.
