Query: Space heater>

I was very disappointed in this heater. I bought it to keep my van warm,or at least keep the chill off. The only thing the heater heated was the heater itself. Unless you sat right near it you could'nt feel any heat coming from it. Even a few feet away you could still see steam coming from your mouth. Even after being lit and running for a few hours,very little heat could be detected in the van.Save your money on this one.
