How to "hack" Mr Heater?

[BeemerBarn]

Hi!

I heat my garage with a 100lb propane tank + 30K to 80K BTU Mr Heater Convection heater.

But I would like to know how I could control the amount of gas entering the heater in order to get %50 or %60 of the minimum 30K BTU setup.

Firstly is it safe?...to plan something like that...

If safe what is the name of the adapter I should look for on the market to plug somewhere in between the 100lb gas tank and my Mr Heater.

I just want to be able to set the heater on a low level once my garage is warm that way I don't have to turn it off too often and I can keep some sort of average temperature without emptying the tank to fast as well.

Can't you adjust the pressure regulator at the end of the hose?
The part that you screw onto the propane tank?

For what you are doing it might be better to just get a small electric to keep your garage warm after the big one brings up the temp?

@y20dth: I whish I could but where can I do that? Is there on the market any kind of low pressure regulator with a handy control? I tried to turn the blue cap as seen on picture but this thing don't seem to be designed for that.

@Mmfh: Thanks for the tip but I try to be AC & electrical heating free with this garage hence the emphasis on insulation.
