I am starting a garage grow through the winter. The garage is insulated, however there is no furnace in the garage. In order to keep some of the heat the lights produce inside the garage I will likely run the scrubber directly feeding back into the garage. This should slightly raise the heat but comes with the problem of minimal air exchange and lack of co2. The area I live stays on average around -4f (-20c) and can get as low as -40f (-40c) one a few occasions.

im looking for suggestions to give me decent heat as well as a little co2.

Any suggestions?

You can actually just buy a cheap propane on demand hot water unit which is the EXACT same thing.
I use the TITAN.

Here's one made by Marey.
I've had a larger MAREY for over a year heating all my hot water in my house.
They're built well.

They are turned on by moving water so you'll have to use a 55 gallon drum of water with a pump hooked to a timer to turn it on and off.
Simple. The heat that is stored in the 55 gallons of water will also help heat your grow room.

Put the Drum outside or in the ground during the summer to keep it out of the grow room and keep temps down.

propane water heater for co2 and heat when lights on and 1-2 ventless wall heaters for heat and co2 for lights on and off. depending on size of room.

Once you seal up, humidity is going to be a problem. A dehumidifier will add heat and reduce the RH when your lights are off.
