Circulating heat from a wood burning stove

My 1200 square foot workshop is heated with a wood burning stove. Getting the heat from this stove circulated throughout the workshop is a bit of a challenge.

The stove is located in the back corner of the workshop. I placed it a bit out of the way so I could maintain a more open space in the front half of the workshop for large projects or vehicles.

The challenge of this out-of-the-way placement is getting the heat distributed.

Existing setup

I have one fan that blows from the back of the workshop toward the front.

This fan is about 4 feet behind the stove. If the fan was too close it might melt.

This fan blows across the hot sides of the cast iron stove. The intent is to pull off some of the heat and carry it forward.

My workshop has 10 foot tall walls. The ceiling peaks at 15 feet in the center.

I need to add a fan that both circulates the heat from the first fan and also gently blows the heat down from the ceiling.

Mounting the fan to ceiling joist truss

I figure the fan mounted up high will gently blow down warm ‘ceiling’ air. I do not want a direct angle blowing down since that moving air will likely be somewhat cold.

I drilled two holes in frame of the fan and attached two eye bolts. The reason for two bolts is so the fan does not rotate by itself.

The two eye bolts are close enough to allow a single large U-bolt to thread through. This large U-bolt will connect directly to the ceiling truss.

I added thread locker to prevent any bolts from working loose from the fan vibrations. I do not really want to start wearing a hard hat in my own workshop.

I mounted the fan upside down. This way the controls on the top face down making it easier to reach from a small step stool.

Setting the fans to ‘auto’

The outlet on the ceilings is tied to the lights. I have three bays of lights and certain outlets are tied to certain lights.

Using these outlets makes turning the fan on and off automatic. If the lights are on, I am probably in the workshop and the fan should be running.

Also, when in the workshop and very tired, simply turning off the lights takes care of the fans. No absent minded forgetting. Simple!
