Oil Unit Heater Installation
Because this range of oil unit heaters can have the flue pipes or chimney exiting the building horizontally , this make them very easy to install , as well as cheaper , as no cranes , lift etc are required to install the flue pipe , especially when the units are installed at low level / ground level – not to mention the health and safety requirements at working at heights are elininated – So no more of this – and the expense and health and saftey associated with it.
Oil Unit Heaters – From 52kW to 208kW – Our Agri-P Range
These warm air heaters can be used in either a free blowing or flexible ducting air distribution, working with a light oil burner. The stainless steel combustion chamber and heat exchanger are constructed in stainless steel AISI 430, either with high performance axial or centrifugal fans, electronic control and safety system.These oil unit heaters are robustly constructed ,manufactured by galvanized pre-coated steel panels fitted with radiant sheet insulation. The range of 5 models have been designed for : warehouse heating, greenhouses heating, factory heating ,workshop heating or basically any where you would like to use oil as your heating fuel, and keep the heater off the floor . A huge range of accessories is available for heater range.Another great benefit of this heater range , is that they can be flued horizontal , for a maximum of 3 metres , which often saves in the time and hassle factor , as opposed to flueing these oil fired unit heaters vertically through a roof.
The Flexiheat oil unit heaters can be supplied in axial fan free blowing format, to be installed directly into the space to be heated, or with centrifugal fan for ducted applications. Heaters are generally arranged for on/off operation.
