Thank you very much for the spec sheet and manual. I am still in the early stages of determining the best method and kiln that can be used in my conditions. Once I try something I will let you know. Best regards

My husband is so impressed with his EcoZoom that we received last month – I had to buy another one! Now he can do all his cooking outside. We also have a Cobb, but it is a pain to clean and the EcoZoom works just as well and is easier to clean. So thanks for a great product.

Honestly I cannot recall the last time I felt quite so inspired and excited to incorporate a technology into my life. I look forward to a more sustainable and sensible future for the youth of today, due in large part to innovators such as yourself. Respect!


I have done approximately four loads to date and have recovered 24 (x50 kg) maize bags from three burns. I weighed one bag and got 13.5 kg, the fourth load is in the kiln now. I therefore get about 108 kg charcoal per burn…


All very clear and well produced…many thanks for sharing this and you’ve done a good job!


Thanks so much for your prompt response to my order request. We bought our Envirofit CH-5200 “stofie” 2 years ago in Kilwa, Tanzania and it is still going strong. I cannot camp without it, it’s the best thing ever! I have ordered one for a friend, and a spare one for me in the event of an emergency!

My little EcoZoom works like a bomb. I use mine once a week. It takes about 30 minutes to heat up. Once it is hot it cooks beautifully with hardly any flame, just glowing wood/charcoal. It uses hardly any wood, so it produces very little smoke. It would save people who cook on paraffin a lot of money. It can be used for potjie cooking, pot bread in a Dutch oven, or for stir fry with a wok. It is very versatile. Cleaning? What cleaning. I don’t bother emptying any ash because there is so little.

Hi, thank you very much for the Portable kiln plans. Regards
