    A man points at a metal heating box containing machinery and a yellow fluid tank; a large white arrow indicates transferring liquid from a red fuel container into the parking heater. www.commaik.de

    The original parking heater in my mobile heater box was equipped with a small tank, which severely limited the heating time. To solve the problem, I fitted the diesel heater in my aluminum box with a larger fuel tank. In this article, I describe step by step how I installed the new 10-litre tank, optimized the heating box and achieved a constant heat supply for my animal house. I share my experiences, tips and challenges, from planning and installing the tank extractor set to the first successful test

    In my search for an efficient and self-sufficient heating solution for my garden shed, I decided to build a mobile heating box with a diesel parking heater. My aim was to create a compact, weatherproof and flexible heating box that not only reliably heats my animal house, but can also be used in the camper, motorhome or for other projects. With the 8kW diesel parking heater, I was able to implement a powerful yet economical solution that provides constant heat even at temperatures of -10°C. In this article, I describe how I planned, built and installed the heating box and share my practical experience from the first tests

    A red and black portable parking heater is displayed on a table with its components, including hoses, wires, a remote, clamps, a silver exhaust pipe, a vent, and a small black bottle in a wooden workshop setting. www.commaik.de

    A diesel parking heater provides efficient warmth for the animal house, workshop and camper – especially on icy winter days. My previous electric heating solution quickly reached its limits at temperatures below -15°C, as the photovoltaic island system could not supply enough energy for the fan heater when there was little sunshine. To reduce the high electricity costs and find a reliable solution for heating the animal house, I opted for the mobile Vevor 8kW diesel parking heater. In my test, I show you how this heater works and why it is ideal for keeping your garden shed, car or roof tent warm in winter. Before I integrated the Chinese…
