Heating my Work shop in the Pacifc NW

I have a detached garage (24x32)with a 10 foot ceiling built with block and it is unheated. The attic is insulated and the cores of the block are pored with zonelite insulation. I am looking at using the Ra240 Solarmax Solar Air Heater to maintain a better temperature so I can work there in the colder / winter months. (warmer for me and helping to keep my woodworking tools from rusting from dampness) My question is simple: Who has used this unit in this type of space and will it produce / maintain a warmer climate?

Rich and Teri;
Sorry if it doesn't answer your direct question, but I wanted to suggest improving the wall insulation in addition to whatever heat-sources you are adding. If by block you mean cinder-block, there is a lot of mass there that will allow direct heat conduction, and a Layer of Rigid, Foil-faced foam, ideally as an outside layer to the building would go far in hanging onto whatever warmth you've got. It can be given siding outside the Insulation, of course, though trimming for doors and windows can take some creativity.

Don't know what your Solar Inputs are like out there, but you might design the racking to allow for additional panels, as you can afford them.

Yes, you can pull all the heat you want from the attic. I have built 5 passive projects from Bellingham, WA to Vancouver, WA. I have passively heated five building of 144' x 74' and 21' tall with my system's of automatic passive heating and passive cooling in Vancouver. The average cost of heating these building's cost's as low as $1.30 a day to 75 degree's. I have built these projects since 1984 and the first one's passive solar system cost $45 + the squirrel cage fan system to pull the heat into the interior of the building. The first project was 95' x 55' by 27' tall. It cost, in today's world, 2008, less then $2.00 per day. Communicate with me and I will explain and suggest a design for your shop. Anachronism
