I'm sure that everyone that reads this has a portable heater that they use somewhere, I have many, buddy heaters, coleman, some I don't know the name of but they are propane. I recently received 2 sunflower heaters that have a regulator? that allows you to hook it up to a 1lb propane tank. There's no way the tank will hold the weight of this heater, some kind of bracket would have to be bought or made to hold it up. Another thing, do these sunflower heaters need a low pressure regulator like what's on a grill to operate, or are they just plumbed into a propane tank and used that way. I'm attaching a pic of the regulator so you can see what I'm talking about. The sunflower heaters are old, I've never had a use for one so I don't know anything about them although I have seen them on 20lb tanks.
