Pellet stove installation question?

Hello Everyone,

While questing for a reasonable RMH solution for my shop I wound up with a pellet stove. Since I have it on hand and my workspace has been averaging around 25F for the last few weeks, I think that I am going to install the pellet stove and save my RMH project for spring time.

The folks that had it installed previously had a simple, straight, horizontal exhaust pipe that extended agout 3' outside the house.

I started to duplicate that but began to wonder if running the pipe 6' vertically, inside the building, then turning horizontal to exit the exterior wall would yield much improvement in heat transfer into the building?

What do you all think? Would the extra 6' of pipe give me much more heat inside the building?

Thanks

Stephen

I can't give you a real definitive answer to your question, but I can tell you about ours.  We have double walled pipe going up about 7 ft and then turning and exiting horizontal 2 or 3 feet.  The exhaust coming from it isn't hot.  It seems the stove is pretty efficient, so while you would surely gain some heat, I don't think it would be a lot.  Much probably depends on the efficiency of your pellet stove.  We have this one:
Cumberland MF3800  

Maybe someone else can give you some hard numbers.

Thanks for the reply.

This stove is a 1990's vintage Whitfield. I don't expect the best of efficiency.

The exhaust is cool enough that I can hold my hand in front of it while running. I am not sure if I can extract much heat but don't want to miss the opportunity if I am mistaken.
 
There's no place like 127.0.0.1. But I'll always remember this tiny ad:
Switching from electric heat to a rocket mass heater reduces your carbon footprint as much as parking 7 cars
