Timberline Wood Stove Insert - Blower Question

[tooljunkie4]

I have and use an old Timberline wood stove to heat the basement. After a couple days of continuous use, it does a pretty good job of warming the upstairs floors. It's old and relatively inefficient, but it is installed and functional.

That said, I'd like to know if any of you have one of these, and have found a satisfactory way to upgrade the blower. This one works, but would be a lot better if it were to move a lot more air and faster. The stove, itself, can be made hot enough to make good use of added flow.

Here's a picture of a very similar unit I found on Ebay. Key differences include that this thing appears to have a dimmer knob on its blower, while mine uses a toggle switch.

I have a Vermont Casting insert and also dissapointed with the output if the fan system. I think the main problem is that the masonry fireplace ***** up a lot of the heat. When I get a chance, my plan is to place Roxul around the back of the fireplace with a sheet metal covering over it.

Moving air faster can cool it. Moving more volume is what you need for a fireplace.

With my 35 yrs experience burning wood you want to blow the cold air to the stove. Try putting a cheap box fan on the floor at s far corner of the room.

Does anyone know where I can find a blower for mine or how to build a box

Just do a search online.

I found mine at, I think, someplace in mid Michigan by doing a search. They had an extensive online catalog, complete with performance specs and drawings detailing the flange and other dimensions.

Don’t remember their name, though.

Biggest heat loss with an insert in my opinion is not having a block off plate at the bottom of the chimney where the liner enters it.Most people and installers dont take the time and effort to add this but it makes a huge difference.

I’m trying to make a blower box for my timberline. Does the blower force air through the bottom and out through the top by the damper? Or does it pull air from the bottom trying to find the best way to set up the blower box I’m making from sheet metal

Do your blower force air from the bottom opening through the top by the damper? I’ve decided to make a blower with some sheet metal but trying to figure out the best way to get air flow around the insert

As you have described, the blower forces air in through the bottom, around the back of the unit, and out across the top of the box by the damper. The inlet is on the viewer's right of the blower box. You can melt plastic with the air that comes off of that stove. Still looking for a way to increase the volume of flow.

Definitely won’t be the prettiest thing around.

Well the blower box is a huge success. I raised the temperature in my back room 2 degrees in under 10 minutes with the fan running. I’ll have to build a box to hold the fan but with basic ducting it’s a working blower. It’s 3 1/4 x 10 inch duct to a elbow that goes to a 6 inch blower fan. The fan isn’t to noisy and moves a pretty high volume. The best part I can move the whole piece during the summer time so it’s not in the way of anything. I’ll post a picture when I come up with a box to hold the fan better.

Very nice. Is the fan durable enough to run constantly for the next four months? If not, you might consider obtaining a spare just in case.

These stoves are borderline useless without blowers. Quite the opposite when equipped as yours now is, and when PACKED with hot coals and dry oak.

They rated the fan for 67,000 continuous hours so we shall see. I’m amazed at the difference already. To reach 78 usually took me all day. In 1 hour I’ve hit 82 and rising.

How many CFM is it rated for?

 

[Kyle39539]

it’s rated for 265 but It’s definitely not moving that much air. I thought 265 would be overkill but I’m happy I went with that size

They do make a different type of duct fan that has more adjustability than the standard duct fan. I use one of these in the 6in version for a bathroom fan. I had to turn it all the way down or else my bathroom was a wind tunnel.

Two winters worth of wood burning have passed since you built your setup. How well has the fan motor held up so far?
