Just got mine going in a temporary installation in my 30x40 similarly insulated garage and it is 6" and took a long time to get it up to temp. I would say a 6" in your building (half the size) would be perfect. I think I will need a larger unit if i am going to be heating two buildings with it...



John,

Thanks for the help. It’s good to know I’m on the right track.

What dimensions (firebox area, length, burn tube diameter, length…) worked for you?

Don

Z,

Thanks a million!! Your numbers are a big help.

Your rocket heater is impressive, and your descriptions very thorough.

I intend to copy your design soon. and need to decide on a 4" or 6" chimney.

Could you list the size of the garage it heats and the R values of the walls and ceiling.

At what outside temperature will it keep the garage at 65F?

Thanks,

Don

Greetings,

This is my first post, after watching Paul’s videos for a long time, I finally got hooked. This is a great forum, and I have learned a lot already.

I have a basic question.

I’m going to heat a 20 x 30 garage, R21 walls, R30 ceiling. My plan is to build a pocket rocket. Will a 4” flue work OK? Or do I need a 6” flue for a building this size?

I plan on getting all the literature to do the job right, with all the proper sizes, etc., but I am in garage construction mode, and now is the time to install the flue.

Thanks
