Due to poor quality rubber hose inside the space heater it failed to work properly. It was no longer a clean burn. Filled the workshop with toxic fumes. Machine mart were of zero help when I telephoned their technical support.
Repaired the machine myself and reported machine mart to trading standards for selling a diesel space heater which does not meet health and safety laws.
Overall customer support and understanding of this serious problem which made the heater impossible to use when needed the most during sub zero working conditions. I'm left very unhappy with machine mart total lack of care and failing to understand the diesel space heater when not burning properly causes Headaches and your eye's to Sting from the fumes being emitted.
After being a customer for 30 year's I will not be using machine mart again after this incident.
