The HCALORY TC2S is a portable diesel air heater built into a toolbox-style housing, rated at 8KW and aimed at vans, RVs, cabins and workshops. It adds automatic start-stop, real-time altitude compensation up to 18,000 ft and Bluetooth app control through the HCALORY app. It runs on either 12V or 24V DC and accepts 110V or 220V AC input, so it suits both vehicle and shore power setups. Against typical Chinese diesel heaters it stands out on the altitude mode and app scheduling rather than on raw output, and it is a more finished package than the SS2/TC2 it replaces.
