Abstract
A heater for burning fuel having a hollow enclosure with an air inlet, and a combustion gas outlet. The enclosure has an exterior heat exchange wall preferably directly exposed to ambient air and an interior surface defining a combustion chamber. The enclosure has a body with front and rear openings into which are fitted a front panel and a rear panel defining joints therebetween. The interior surface of the enclosure is coated and joints are sealed with heat resistant anti-oxidant material, for example: porcelain enamel, having a co-efficient of thermal expansion not substantially greater than the co-efficient of thermal expansion of the enclosure.
Claims12
A heater for burning fuel comprising:
- a hollow enclosure with an air inlet, and a combustion gas outlet, the enclosure having at least one interior wall adjacent a combustion chamber, wherein:
- the interior wall is coated with heat resistant anti-oxidant material having a co-efficient of thermal expansion not substantially greater than the co-efficient of thermal expansion of the interior wall.
A method of manufacturing a heater for burning fuel comprising:
- forming a hollow enclosure with an air inlet, and a combustion gas outlet, the enclosure having an exterior heat exchange wall exposed to ambient air and an interior surface defining a combustion chamber, the enclosure having an enclosure body having front and rear openings with a front panel and a rear panel fitted into the front and rear ends defining joints therebetween, and
- coating the interior surface of the enclosure and sealing said joints with heat resistant anti-oxidant material having a co-efficient of thermal expansion not substantially greater than the co-efficient of thermal expansion of the enclosure.
