Hi Max, back in 1982 I purchased the Kozy heater from you, I think I was one of the first in Canberra to get on. My Son & I have just set up a new workshop, so to keep warm we would like to purchase a new one. Is it possible to purchase direct from you. Cheers for now. Thank You. Hi Peter, just a short note to say our heater is a cracker, we have a workshop 30 m. long, & 5 m. ceiling & the 2 end bays we use for working in are just great on the minus 3s & 5s we have had lately. Once again thanks mate. Cheers. John.
