Powerful Dual Chamber Heating
The Master B300 Oil Fired Space Heater delivers serious heating performance with its dual chamber design. Run both chambers for full 88kW output or a single chamber for a reduced 44kW output. This flexibility makes it ideal for a wide range of industrial and commercial applications.

Efficient & Cost-Effective Heat
With fuel consumption between 4.2–8.4 litres per hour, the B300 provides efficient, direct heat exactly where you need it. The integrated 105-litre fuel tank allows for up to 23 hours of continuous use on half power, reducing downtime and maximising productivity.

Tough & Built to Last
Constructed with a stainless steel combustion chamber, thermally protected motor and robust outer shell, this heater is designed to withstand challenging conditions. It is suitable for demanding sites such as warehouses, workshops, construction projects, agricultural facilities and more.

Easy to Move & Maintain
The integrated trolley, large wheels and handle make transporting the heater around site straightforward. Serviceable components like oil and suction filters, along with an oil tank level indicator, make upkeep simple and cost-effective.

Safety & Control Options
Electronic flame control with photocell, dual oil filters and an overheat thermostat provide safe and reliable operation. For added convenience, the unit is thermostat-compatible, allowing automated temperature regulation and improved fuel savings.
