  • Upgrading the diesel parking heater: Installing a tank extension for the mobile heating box

    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

  • Build your own mobile heating box: The best DIY solution with an 8kW diesel parking heater

    A heating box containing technical equipment, including a white plastic tank with a blue cap, wiring, and black components, is open on a stand in a workshop with wooden walls. www.commaik.de

    I have built a mobile heating box with an 8kW China Diesel parking heater that can reliably heat animal houses, garden sheds, campers and tents. The heater box had to be compact, weatherproof and mobile, but at the same time offer enough space for the diesel heater, fuel tank and accessories. In this article, I describe how I planned the heating box, installed the diesel heater and finally put the box into operation, and share my building instructions and my experiences as well as practical solutions.

    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…

It is now time for a review and a summary of the individual measures.

    My Napoleon P500 gas grill will be the centerpiece of my new backyard kitchen. The outdoor kitchen is still under construction, but I already have to think about installing the gas barbecue. In addition to the work surface of the Napoleon Prestige 500 – which should be at the same level as the rest of the worktop – the ventilation of the gas grill and the supply of gas and electricity must also be considered and planned. My aim is to no longer be dependent on the batteries in the grill in the future. Rather, the electrical functions such as the lighting and ignition of the Napoleon should be ensured…
