Hi BK Actually there are 10 1 inch tubes on mine 30.000 BTU.s I would not run my stove with out one well worth the money lots of heat and low stack temps I aso have a 6' Vogelzang witch I have to use yet internal snap switch No way to turn it off The magic heat has auto or manual switch you can run all the time or put it on auto and it kicks on at 130F off at 110F Plus like you said built in cleaning rod pull in and out cleans the pipes of Fly ashbksaun wrote:I use a Vogelzang, it is absolutely not worth bothering with, I get more heat off a good fart!
Matthaus uses the Magic heat brand, ask him. I believe they are a much better unit.
The vogelzang only has 3 heat exchanger tubes and no way to clean them except to take it apart, The Magic heat has 6-7 heat exchanger tubes and an external rod to to clean the fly ash. A much better design.
Yes MR. Matthaus Just stating what the instruction book that came with the MagicMatthaus wrote:In answer to your questions: Yes they do work, although you would have to have a 500* flue temp to recover 35,000 btus ; Yes they do accumulate fly ash, although there is a scraper connected to the knob on the front if you do that once a day it will allow one "disconnect from flue and clean" event per year; and finally it reduces the stack temp by around 15% or so, unless you have some other kind of problem this will not reduce the draft by any measurable amount.
njoy the science project!

Hi biil4117 all you need is 8 to 6 reducer they do not take up any more space then what your pipe does I had to use one on mine I also have a 6" flue the Magic was a 8" it is just a collar that hooks up to you pipe Just abill4117 wrote:im using a reclaimer myself similar to the vogelzang, it's a 4 tube and it does wonders. i do own a magic heat exchanger but its for an 8 inch pipe and i have 6 inch with my stove. unfortunately i don't have enough room to expand to 8 inch hook up the magic heat and reduce back to 6. make sure with the stoker you have hot enough flue temps or you'll run the risk of reversing the draw on the chimney. most newer stokers are very efficient and lose minimal heat out of the flue.
