  • Hcalory TB MAX 8 kW diesel heater in a practical test – compact all-in-one heater for camping, workshops and motorhomes

    A portable hcalory diesel heating unit sits inside a metal box with an open lid, next to a light gray wooden wall. Various hoses and a fuel tank are visible, along with ventilation pipes extending from the box. www.commaik.de

    The Hcalory TB MAX 8 kW diesel heater is one of the most modern diesel parking heaters and combines a compact design, smart app control and high heat output with low consumption. In my detailed test, I show how the diesel parking heater performs in the motorhome, when camping or in the workshop, which technical innovations distinguish it from older Vevor models and which safety functions make the heater special. In addition to the manufacturer’s portrait of Hcalory, it covers design, technology, installation, CO monitoring and automatic start-stop – right through to a comparison with other diesel parking heaters and my practical test in the animal house and garden shed.
