Heat exchanger for stove pipe

[Darkoming]

Just wondering if anyone has used one of these heat exchanger that fits in the stove pipe of a fireplace. I was also wonder if they are legal to run and how you clean the chimney with it in place as the exchange blocks the pipe off. They claim that you can recover up to 30% of waste heat. Is it worth the money or is it just a pipe dream.

i would worry about scrubbing to much heat from the flu gas causing it to condensing and not get the proper stack effect for proper venting

Crazyperch took the words right out of my mouth.

So in other words a pipe dream. Thank you for responding. I didnt really think about the proper venting of the gasses and cooling of the smoke to much causing it to condense on the pipe. Last thing I need is a chimney fire. One of my concerns heating with wood.

what about the catalytic insert that fits into the base of the pipe ?

Almost all of the modern wood burning stoves for residential use are either of catalytic design or employ a secondary burner system to improve efficiency and reduce particulate emissions.

I believe in most jurisdictions the stoves must have one of the two systems to meet current codes and standards.

In the wood stove that is installed in the house it has the main burn chamber, then a firebrick that separates the top were the stove pipe connects. I currently just have an air control in front of the stove to try and slow the burn down but I'm finding that I'm going through a lot of wood for the heat that the stove is putting out. I was just wondering if there are ways to make the stove more efficient and get more heat for the amount of wood that I'm burning. I'm new to burning wood for heat so just looking for advise on best ways to be efficient.

Just as already mentioned most modern heater with 2 stage burn have removed almost all the BTU heat value out of the wood before smoke goes up the chimney. Buy more wood and you will be warm this winter.

Also make sure all seals and gaskets are in good order, especially the door gasket. If you have leaks you're letting in more air than you want, leading to faster burns.

Modern stoves built to code limit how much you can restrict inlet combustion air. They do this to ensure adequate heat in the firebox preventing too smokey a fire and also to keep the flu hot enough to limit creosote deposition.

Thank you to all those that replied. I guess I will continue to feed the fire so to speak. As I said I'm new to heating exclusively with wood. I've had a Fisher stove 25 years ago but it wasnt used to solely heat the home (just lit it to take the chill off the basement). Not really familiar with the new stoves and remembered the old stove put out a lot more heat. Guess I'll have to get a lot more wood to get me through the winter. Thank you
