Not sure. Probably there is but why would your want one? If you do not have natural gas, getting a propane tank may be a good thing anyhow. (Then you can think about a gas dryer and water heater, not to mention the fact that cooking with gas is definately where its at.) Heating with propane is more cost efficient than heating with electricity. A large electric heater like that will require a dedicated circuit and a large wire size to run it. It may not be much more to run the gas line.
