Direct Or Indirect Oil Fired Heating ?

Indirect Oil Fired Heating

An Indirect Heater segregates the combustible by-products or flue gases from the warm air required for heating purposes. Most commonly, the heater stands outside the structure and directs the clean, dry air from the nose cone inside via a length of high temperature, flexible ducting. The flue gases subsequently vent directly into the atmosphere. Whilst the heater can stand inside the structure and the flue gases vented out, this is invariably the more difficult option.

On average the EC heaters are 86% thermally efficient, with 14% of the gross heat output being flue gases.

Direct Oil Fired Heating

Direct Fired Heaters do not segregate their flue gases, which are therefore emitted into the heated environment. As the direct fired units can not be ducted they stand inside the structure and, as with all forms of Direct Fired Heating, it is imperative that the area has an adequate level of ventilation.

When ever using oil fired heaters it is vital that oil spillage precautions are taken.
