RocwooD RWDHT2 Diesel Space Heater (Yellow, 30kW)

What size area can this heater effectively warm?

This heater can effectively heat areas up to 100,000 square feet with its 30kW output and 100,000 BTU capacity. The built-in turbo fan moves 750 cubic metres of air per hour, ensuring even heat distribution throughout large workshops, garages, warehouses and factory units. The actual heating area will depend on insulation levels, ceiling height and ambient temperature conditions.

How long does the 38-litre fuel tank last?

With fuel consumption of 2.4kg per hour, the 38-litre tank provides approximately 13-15 hours of continuous operation depending on the specific fuel type used. Diesel weighs approximately 0.85kg per litre, so a full tank contains roughly 32kg of fuel. This extended runtime makes it suitable for all-day heating without frequent refuelling interruptions.

Can this heater be used indoors safely?

This heater is designed for indoor use in well-ventilated areas such as garages, workshops and industrial buildings. It must never be used in living spaces or poorly ventilated areas. Adequate ventilation is essential as diesel combustion produces carbon monoxide and other gases. Always ensure proper air circulation and never use in bedrooms, living rooms or enclosed spaces without adequate ventilation.

What types of fuel can I use in this heater?

The heater operates on diesel, kerosene or paraffin fuels. White diesel and red diesel both work effectively, with red diesel often being more economical for heating purposes. When using kerosene or paraffin, ensure adequate ventilation as these fuels may produce more fumes and smoke than diesel. Always use clean, good-quality fuel to maintain optimal performance and prevent damage.

Does the heater require electricity to operate?

Yes, the heater requires mains electricity to power the built-in electric turbo fan and control systems. The fan is essential for proper heat distribution and safe operation. Without electrical power, the heater cannot function properly as the fan circulates heated air and helps maintain safe operating temperatures. Ensure a reliable electrical supply is available at your intended location.

How easy is it to move this heater around?

The heater is designed for portability with 8-inch wheels and a full handle kit included. Despite weighing 22kg, the wheeled base allows single-person transportation across workshop floors and between different work areas. The robust steel construction maintains durability whilst the handle provides secure grip for manoeuvring. The wheels are sized appropriately for typical workshop floor surfaces.

What safety features does this heater include?

The heater incorporates cut-off protection against overheating to prevent dangerous temperature levels and potential fire hazards. An adjustable thermostat provides precise temperature control, automatically maintaining desired heat levels without manual intervention. These safety systems work together to ensure safe operation whilst preventing energy waste and maintaining optimal working conditions throughout extended use periods.

What warranty coverage is provided with this heater?

RocwooD provides a 12-month domestic user warranty covering manufacturing defects and component failures under normal use conditions. Business or continuous commercial use will invalidate the warranty coverage. Full warranty terms and conditions are available on request before purchase. The warranty covers parts and labour for qualifying repairs but excludes damage from misuse, poor maintenance or inappropriate fuel types.
