Hi guys, yesterday I managed to bag a greenhouse heater plus gas bottle for the princely sum of twenty whole English pounds! I've heard of hotbox before but never owned a heater by them, and even though I've googled, binged and even looked on the hotbox Web site, I can't for the life of me find any info about this model. It works as it should and had my unheated, uninsulated greenhouse up to 12⁰ yesterday when I ran it for half an hour. Has anyone any experience of these, or know where I can find any info about them, manual, output etc.
