I have a contract to do one at La Rosa campsite where we installed composting toilet in Gypsy van. I am considering using a cast wood stove and putting stainless steel through to catch heat, but a small stainless burner may be cheaper. Tub manufacturers use one called a Chofu, but they are expensive. cheers, Kev Kevin Ison eekos Limited The Old Hackfall Grewelthorpe HG4 3BW Company Number - 5504935 www.eekos.com ------------------------------------------------------------------------------ No virus found in this incoming message.
