I have two of those propane forced-air space heaters; big orange tubes that look like jet engines on afterburners when running. One is rated at 12-32kW, the other is 26-43kW, so they are both a little big for the average garage but great for a larger workshop, barn, warehouse, etc. They have been used, to dry out a church hall after a flood, but are clean and shiny and work fine. When I get a round tuit they'll be going on ebay, starting @ £59.99 and £79.99. New they would be around £200-250, However I am open to offers from ukrmers, collection from south essex, or UR by arrangement.
