The first suggestion is a good one.I am an energy & environmental engineer.Anything that produces instant heat is expensive.The cheapest alternative is the old gas bottle heaters.My grandad still to this day attaches a glass of water to the front of the grill.This i later found out increases the humidity and the evaporating water oxidises the air.No more stuffy or dry air.Problem is getting a hand with a heavy bottle of gas.
