12V and 24V diesel air heater kit for vehicle and boat interior heating with engine preheat function

This comprehensive diesel air heater kit is designed to solve heating challenges in a variety of vehicles and marine applications. Supplied as a complete package with all necessary components, it provides a powerful source of warmth for truck cabs, camper vans, motorhomes, workboats, and battery storage vehicles. Operating efficiently on diesel fuel from its own 10L tank, the heater delivers adjustable warmth directly into your living or working space. A key additional benefit is its ability to preheat your engine's coolant before a cold start, which helps to reduce mechanical wear and can extend engine life. The kit's compatibility with both 12V and 24V electrical systems, coupled with multiple power outputs, makes it a versatile heating solution for professional drivers, leisure travellers, and marine users alike.

Features and Construction

The heater is built with a compact structure to facilitate installation in confined vehicle spaces. The supplied instructions guide you through connecting the electrical, fuel, and air systems. All critical components for a professional-grade installation are included in the box.

Material and Build

The core heater unit features a robust metal and plastic construction housing the combustion chamber and heat exchanger. The fuel delivery system is comprised of a plastic 10-litre tank, a metal oil pump, and durable rubber and metal oil pipes, all secured with the provided clamps. For exhaust management, a metal exhaust pipe is supplied to safely vent gases outside the vehicle. Electrical integration is handled via a standard main wiring package, simplifying connection to your vehicle's battery.

Size and Practical Fit

The kit is designed for practical installation. The host installation board provides a secure mounting point for the main heater unit. A full set of hardware—including nuts, tapping screws, and cable ties—allows for firm attachment to vehicle structures. The assortment of small, medium, and large hose clamps ensures a leak-proof connection for all fuel and air lines, accommodating different pipe diameters. The included silicone seal aids in creating airtight fittings where required.

Uses and Placement

This heater addresses specific thermal management needs in environments where standard vehicle heating may be insufficient or where the engine is not running. Its applications are broad, covering both commercial and leisure sectors.

Event or Professional Use

For professional drivers of long-haul trucks or delivery vans, this heater provides essential cabin warmth during rest periods without needing to idle the main engine, saving fuel and reducing emissions. The engine preheat function is particularly valuable for fleet vehicles operating in cold climates, as it helps ensure reliable morning starts and protects the engine from cold-start strain. The ability to clear windscreen frost also enhances safety and visibility before setting off.

Everyday Home Use

For leisure users, this heater transforms a campervan, motorhome, or boat into a comfortable four-season space. It delivers consistent, adjustable heat for living areas, making early mornings and evenings more pleasant. The independent 10L fuel tank means heat is available even when the vehicle's main fuel is low or when you wish to conserve it. On boats, it can provide welcome warmth in the cabin during evening fishing trips or overnight stays.

Benefits and Buying Value

The value of this product lies in its integrated functionality, completeness, and the practical problems it solves. It moves beyond being a simple heater to become a multifaceted thermal management system for your vehicle.

Reuse and Low Maintenance

The heater is designed for long-term use with straightforward maintenance. Key serviceable items like the air filter and oil filter are standard components, making future replacements simple. The robust metal construction of the exhaust and intake pipes is intended to withstand the vibration and temperature cycles of vehicle use. Following the basic care of checking filters and connections can contribute to the unit's ongoing performance and its characteristic low fuel consumption.

Why Choose This Product

Choosing this diesel air heater kit provides a self-contained heating system. The inclusion of every part needed for installation—from the wiring and fuel tank down to the hose clamps and seals—means you receive a genuine ready-to-fit solution, not just a main unit. The flexibility to select a 2KW, 5KW, or 8KW model in either 12V or 24V configuration allows you to match the output precisely to the size of your space and your vehicle's electrical capacity. This tailored approach, combined with the dual benefits of cabin comfort and engine care, offers a comprehensive answer to vehicle heating needs.
