Master indirect fired diesel heaters are industry-leading space heaters, ideal for heating a huge range of spaces quickly and safely. Indirect fired space heaters feature an integrated flue system, which separates the fumes produced during combustion from the warm air. These heaters can be placed outside the space that you wish to heat and ducting can be used to vent the warm air into the space, whilst the fumes are exhausted outside. This method of heating makes these space heaters perfect for heating enclosed, poorly ventilated spaces safely such as halls, workshops, marquees, tents and much more. Master indirect space heaters are available in a great range of sizes - so whether you need to heat a small marquee or workshop, or a large construction site or warehouse, there is a suitable heater in the range. We can supply all of the accessories you need, and we even supply complete package deals which include all accessories required - such as ducting, flue, thermostat and more. These package deals give you everything at a reduced price and with free delivery!
