I'm in the process of building a detached garage/studio in Portland, Oregon. We're getting ready to start roughing out the electrical, and we're looking for some suggestions as to the best way to heat the studio.
The studio portion is around 170 square feet, 2x6 construction. The ceilings are vaulted, 2x10 rafters with two new 4x4 skylights. There are french doors at one end and a 9x5 window on the south side. My rough calculation is that we'd need something that can generate around 7,000 BTU for the space.
My wife will be painting in this studio using oil-base paints.
We don't have natural gas service to our house, so we're probably looking at electric heat. We're currently paying around $0.085/kwh, around 1200 kwh per month for our 1928 house.
Any thoughts? Baseboard heating? In-wall heater? Some kind of radiators? Heat pump? We'll probably use a window air conditioner in the summer. An electrician friend suggested a reversable ceiling fan to help push warm air back down in the winter.
Here's a website showing my construction progress:
