Mudiro 8 kW Diesel Heater: Specifications and Practical Use

The Mudiro 8 kW diesel heater has a stated heating output of 5–8 kW and an integrated 5-litre fuel tank. It is intended to heat a range of spaces and can be controlled via Bluetooth, a remote control or an LCD panel. However, there is an inconsistency between its stated fuel consumption and heating output that should be checked before choosing a unit.

Heating output, fuel consumption and tank

The stated heating output is 5–8 kW, with diesel consumption of 0.12–0.46 litres per hour. How long it takes to warm a room or workshop depends on the size of the space, its insulation and the outdoor temperature. It is therefore not possible to promise that a space will heat up within a few minutes.

The output and fuel consumption figures are difficult to reconcile. Approximately 0.46 litres of diesel contains 4.6 kWh of energy, so consuming that amount in an hour would provide less energy than the 5 kWh of heat implied by a 5 kW output over one hour. Check the output and consumption figures for the specific variant and operating conditions before selecting a heater.

The integrated tank holds 5 litres. Running time on one tank depends on actual fuel consumption and the heater setting. A fuel reserve is useful when travelling or working in a workshop where refilling is inconvenient.

Power supply and use

The heater is listed as supporting 12 V, 24 V and 230/240 V AC supplies, allowing for potential use in vehicles, trucks or workshops. Before connecting it, check the requirements of the specific variant and how it must be connected to the chosen power source. Diesel fuel does not replace the electrical supply needed to operate the heater.

The stated operating temperature range is −40 to +40 °C. Suitability in cold conditions also depends on the installation and operating environment. When choosing a heater for a workshop, vehicle or other space, consider the required output, electrical supply and options for safely routing exhaust gases outside.

Controls and safety features

The heater can be operated via Bluetooth, a remote control or an LCD panel. A temperature sensor with automatic switching on and off allows regulation according to the selected setting without constant manual intervention.

Listed protections include overheating, overload, reverse polarity and overvoltage protection. These features do not replace correct installation or address every risk associated with burning diesel.

Installation and carbon monoxide

Follow the manufacturer’s installation instructions and ensure a proper supply of combustion air and an exhaust route outside the heated space. Exhaust gases must not be allowed to re-enter the interior or vehicle. Provide suitable ventilation and use a working carbon monoxide detector. Carbon monoxide is a dangerous gas that cannot reliably be detected by smell.

Do not use the heater in an enclosed space without a correctly installed exhaust outlet. If you are unsure about the connections or exhaust placement, have it installed by a suitably qualified person.

Design and dimensions

The heater has a black and red finish. The stated package dimensions are 49 × 20 × 49 cm. These are not the dimensions of the heater itself and cannot be used to establish how much installation space it needs.

A length of 1.5 metres is listed for the wired control panel. Before planning where to place the controller, check whether this figure refers to the cable length.

Running costs and emissions

Diesel consumption affects running costs and how often the tank needs refilling. As a combustion appliance, the heater produces emissions during operation. Without comparable data, it is not possible to claim that the Mudiro produces fewer emissions or is more environmentally friendly than another heating source.
