12V and 24V Diesel Air Heater Kit for Truck, Van, and Motorhome Cabin Heating

This auxiliary diesel air heating system offers a practical solution for maintaining a comfortable temperature inside a wide range of vehicles. Operating on a 12V or 24V electrical system, it draws diesel from its included tank to produce heat, serving two key functions. Primarily, it heats the cabin interior of vehicles like trucks, vans, motorhomes, campers, and boats, which can also help eliminate frost on windows. Secondly, it can be configured to preheat an engine's coolant, a process that aims to reduce mechanical wear when starting an engine in low temperatures. Available in three power ratings—2KW, 5KW, and 8KW—it allows you to select a model suited to your vehicle's size and heating needs. The product is noted for its relatively low fuel consumption and emissions, and it comes as a comprehensive kit with every component needed for installation.

Features and Construction

The heater's core value lies in its versatile specifications and complete package. You choose between 12V and 24V operating voltages and one of three heating outputs. The construction is compact, and the manufacturer emphasises that it includes installation instructions to aid the fitting process.

Material and Build

The system utilises durable materials for critical components. The exhaust pipe is metal, designed to handle hot gases safely. A silicone seal is included to ensure airtight connections, while nylon cable ties and an assortment of small, medium, and large hose clamps provide secure fastening for all pipes and cables. The host unit mounts onto a supplied metal installation board.

Size and Practical Fit

While exact unit dimensions are not specified, the compact structure is highlighted as a feature, suggesting it is designed to fit into the often confined spaces available in vehicle engine bays or undersides. The kit's completeness is its main practical advantage, containing all wiring, the oil pump, filter, a 10L fuel tank, and every necessary pipe and fastener. This means you receive a single package with everything required to connect the system to your vehicle's fuel line, electrical system, and ducting.

Uses and Placement

This heater is designed for mobile and stationary applications where diesel fuel is available. Its primary use case is in vehicles, but its functionality extends to any enclosed space attached to a vehicle's power system.

Event or Professional Use

For professional drivers of freight trucks, lorries, and accumulator vehicles, this heater provides cabin warmth during long hauls or mandatory rest periods without needing to run the main engine. This can contribute to driver comfort and may help with fuel economy. The engine preheat function is particularly valuable in cold climates for commercial fleets, as it can facilitate easier cold starts and is intended to reduce long-term engine wear.

Everyday Home Use

For leisure users, it is an ideal solution for motorhomes (RVs), camper vans, and boats. It allows occupants to heat the living space independently of the vehicle's propulsion engine, enabling comfortable habitation in cooler weather whether parked or at anchor. The ability to set an arbitrary temperature via the handle switch gives users direct control over their interior climate.

Benefits and Buying Value

The value of this product stems from its dual functionality, fuel efficiency claims, and the convenience of a full kit. It addresses specific comfort and mechanical concerns associated with vehicles in cold environments.

Reuse and Low Maintenance

The system is built for ongoing use across multiple seasons. Once installed, it operates independently, requiring only a supply of diesel fuel. The inclusion of a fuel filter and the design for low consumption suggest a focus on sustained, economical operation. Maintenance would primarily involve checking connections and replacing the air filter as needed.

Why Choose This Product

Choosing this heater kit means selecting a specialised product that targets a clear need: reliable auxiliary heat for vehicle spaces. The key decision points are the voltage (12V or 24V) to match your vehicle's electrical system and the power output (2KW, 5KW, 8KW) to match your required heat output. The inclusion of a comprehensive installation kit—from the main wiring harness and oil pump down to the hose clamps and screws—removes the guesswork and extra cost of sourcing parts separately, providing a cohesive solution for a technical installation.
