12V and 24V diesel auxiliary heater kit for truck, camper, and motorhome cabin heating

This auxiliary heater provides a practical solution for heating the interior of various vehicles, from commercial trucks and buses to leisure vehicles like motorhomes and camper vans. Operating independently of the main engine, it uses diesel fuel via a self-contained 10-litre tank and pump system. Available in six specific power configurations—12V 2KW, 12V 5KW, 12V 8KW, 24V 2KW, 24V 5KW, and 24V 8KW—it allows you to select the output that matches your vehicle's size and insulation. A key secondary function is preheating the engine coolant, which helps reduce mechanical wear caused by starting a cold engine. Supplied as a comprehensive kit in a red and black finish, it includes all necessary components for installation.

Features and Construction

The heater is designed as a complete system for adding auxiliary heat to vehicles. Its construction focuses on providing reliable heating and straightforward installation using the supplied parts.

Material and Build

The kit includes several metal components crucial for durability and function, such as the exhaust pipe, host installation board, tapping screws, nuts, and hose clamps. A silicone seal is provided for airtight connections. Plastic and nylon elements, like the cable tie and likely parts of the housing and hoses, are used for lighter-weight fittings and insulation. The assembly is designed to be compact, with all pipes (intake, exhaust, drain) and the control air outlet included to form a closed system.

Size and Practical Fit

While exact unit dimensions are not specified, the heater's compact structure is noted, implying it is designed to fit in the often limited space available in vehicle engine bays or compartments. The comprehensive nature of the kit—including the main heater, a 10-litre fuel tank, oil pump, filter, and all piping—means everything required for a full installation is present. The variety of hose clamps (12 small, 3 medium, 2 large) allows for secure connection to different diameter hoses on various vehicles.

Uses and Placement

This product serves distinct purposes for both professional drivers and leisure vehicle users, enhancing comfort and vehicle maintenance in cold conditions.

Event or Professional Use

For professional freight and logistics, the heater is directly applicable for heating the cabs of trucks and vans, improving driver comfort and safety during long hauls in winter. It can also be used in accumulator cars and other specialised commercial vehicles. The engine preheating function is particularly valuable for fleet vehicles that operate in low temperatures, as it helps maintain engine reliability and reduce maintenance costs associated with cold-start wear.

Everyday Home Use

For personal use, the heater is ideal for motorhomes, camper vans, and boats, providing a source of warmth that does not rely on the main engine running, thus conserving battery power. It can eliminate window frost and maintain a comfortable temperature inside the cabin or living area. For vehicles stored outdoors in winter, the engine preheat function ensures easier and less damaging cold starts, which is beneficial for both daily drivers and seasonal vehicles like classic cars or boats.

Benefits and Buying Value

Choosing this heater kit offers tangible advantages focused on functionality, self-sufficiency, and long-term vehicle care.

Reuse and Low Maintenance

The product is built from durable materials like metal for critical exhaust and structural parts. With a complete set of installation components provided, there is no need to source additional parts, which simplifies the fitting process and future servicing. The inclusion of a fuel filter and multiple hose clamps supports a reliable and maintainable system. By preheating the engine, the unit can contribute to reduced engine wear over time, potentially extending the vehicle's operational life.

Why Choose This Product

This heater stands out due to its dual functionality for both cabin comfort and engine care, its compatibility with common 12V and 24V vehicle electrical systems, and its use of readily available diesel fuel. The option to select from six different power outputs (2KW, 5KW, 8KW in both voltages) means you can match the heater's capacity precisely to your vehicle's size and your heating needs. The fact it is supplied as a full kit with detailed instructions makes it a practical purchase for DIY installation, providing everything needed in one package.
