Heating My Attic
I am thinking about and planning ahead as to how I will heat my finished attic space. I have already had some heating and cooling guys come in and explain that based on my setup there is not a really good way to run ductwork to my attic. With that said, are there any safe options. The space is about 250 sq ft. It really is only a few degrees cooler than the main level, and I have added new insulation to the attic. I didn't want to use space heaters for safety reasons. Any other affordable options?

have you considered baseboard heaters?
Run them on their own thermostat in the attic space.

I have considered them. Are they difficult to install? I had some electric work done a few months back. There are two outlets for each of the two rooms in the attic space. Suggestions??

Hello Cibula:
Baseboard heaters run on 220v so, you would need another line up there. The heaters come in different lengths and the amperage depends on the length. The wire size depends on the amperage drawn by the heater.
Rural Electric Co-ops have said it is the most economical way to heat; when you are not using the room you can turn it off. Using a thermostat on it will cause it to cycle on or off as needed. It is probably the most economical to install too; black to black, red to red, white to white and bare ground to a green headed screw.

Two questions:
1. What would a ballpark cost be for having a baseboard heater installed.
2. Has anyone heard anything about the portable baseboard heaters? I found a few that heat up to 150 sq ft. ( I would need 2) , they plug into a regular 120v outlet. Here is the website I saw on the portable heaters.

I can't give you a price to have it installed but I can tell you the portable ones are "rinky-dink"; I wouldn't recommend them. You should not run more than one portable on a circut.

Let me know if this sounds right. I was thinking of running 10/3 wire from my panel to my attic where the baseboard heaters would be installed. I was told to first run it to a switch where my thermastat would be placed, then from there to my heater. I was thinking of leaving all the connections for the electrician but save myself some money by doing the labor part. I would use a 2 pole 30 amp breaker as the heater will run at 1500 watt. Sound good?? Any other twists as to how I would install two different heaters in the space on one thermastat?

Upon further inspection it looks as if I could add a supply line from my furnace to the attic. I probably could add just one. Based on cost and effectiveness which would be cheaper: ductwork or electric baseboard? I may not have enough room on my panel to add another circuit which would mean adding more tandems.

Hello Cibula:
I would favor the duct run for several reasons:
1. It would be economical to install and use
2. It would also give you air conditioning (if you have central air)
3. It would circulate the air throughout the main level and the attic
4. You can reserve the electrical panel for other additions later.

You could run the duct in round, sheet metal pipe or use wall stack between the studs. One run would be sufficient and the return air would work as long as the door is open or make sure you end up with an inch or more space under the door. I think you are really on to something. We would like to see pictures of your progress.

Thanks Glen. I am going to contact an HVAC guy and see what we can conclude. I may decide however to do the job myself. The place that I am considering using for the supply would put the vent in the middle of the room. While, one is better than none, do you think it would be NECESSARY to add two. If I add two, I would probably have to use a "T" or "Y" to split the supply. One would go to one side and the other giving air to the other side of the room. But splitting the supply would cut down on air flow so it may not really do much. If I put two supply, I most likely would not have room for a return. Is there one that you would prefer. (1 supply, 1 return; 2 supplies, no returns). The space is about 250 sq. ft and is open to the main level. (no door)
