100% Clean Warm Air: Only clean, fume-free warm air is blown out of the front of the heater to heat the space.

Flue Gas Exhaust: Combustion by-products are exhausted out of the top of the heater. Sections of flue pipe are available separately, allowing you to safely vent exhaust fumes away from the space.

Ducting Connection: Lengths of ducting can be attached to the heater, in order to direct the clean warm air into the space that you need to heat. This makes it ideal for heating enclosed areas safely, such as marquees and tents, workshops, warehouses, areas on construction sites and much more.

Available in 240v or 110v: You can select the most suitable option for your space.

Tough & Robust Design: Featuring durable phosphated body panels with powder coating. Designed to perform in challenging areas, including construction sites, workshops, warehouses, agriculture, events and more.

High Quality Features: High efficiency heat exchanger (91%), combustion chamber heat resistant up to 850 °c, internal fuel tank for up to 16 hours burning duration, burner relay, photocell flame control and high pressure pump with 1-way pipe system help to ensure reliable, effective and safe performance.

Portable Design: Large wheels and a handle make the heater very portable. It is easy to transport, position and re-position when required on site.

Thermostat Connectivity: An optional thermostat can be connected to these heaters, allowing you to set a required temperature within the space. The thermostat will switch the heater on and off as required in order to maintain the set temperature. This saves fuel and adds extra convenience.

Overheat Thermostat: Shuts down the heater automatically if it overheats, to prevent accidents.

Effective Heater!

I ordered this heater for my shed to enable me to stay warm when I am working on my motorbikes. The heater is very good and certainly does the job. My order arrived really fast and the sales adviser I spoke to online was very helpful, he really did help me decide which heater was best suited for my requirements.
I would highly recommend this item for anyone looking to warm up their working spaces.
