Aluminum is just not a useful material for a heating system 
liner. We received a phone call from a customer whose chimney in Beverly Ma was blocked and the heating system had been red tagged by the gas company that services their boiler. Look at what we found when our emergency services technician Jon White arrived on the scene.
You can see here through the breach that the aluminum liner is rusted and disintigrated. For this and a few other reasons, we won't install liners made from this material.
Now, Here is a photo of Josh, our certified chimney sweep, removing the bottom half of the liner. We created a slide show for this that we're intending on posting as soon as it's optimized. The pictures are very informative an
d should assist any home owner looking into liners for their chimney and are curious about why aluminum is so much cheaper to buy. Buyers beware!
If you've ever been curious about how sturdy these aluminum liners are, check these photos out that our certified chimney sweep Jon White took to demonstrate the hazzards associated with using aluminum liners.
Please leave your comments, they help spread the word about the hazzards in lining chimneys with aluminum chimney 
lining material. One cheap fix early on, in this case, caused extra expence in the future. This home owner will have to purchase a new lining system soon. When it comes to lining materials, aluminum vs stainless steel, we choose stainless steel. You can stand on our liners and they're guaranteed for life!
