CUSTOMER REVIEWS

Rated 4.6 out of 5 by 7 reviewers.
Rated 5.0 out of 5.0 by Must have for outdoor wood burner users I confess I was lured into purchase of the cheap stainless steel ( not stainless at all) Canadian manufactured outdoor wood burner boiler. Even with keeping the required chemicals in the water at all time within three years it leaked like a sieve. Rusted in every seam. The real problem is this so called stainless steel is almost impossible to weld as compared to mild steel. This boiler was guaranteed 10 years except if it leaks then you own it. This boiler liquid has saved my boiler. Period. Whether it is the tubes inside the firebox leaking or the seam at the lower rear, this stuff works with absolutely no issues for the air to air heat exchanger or the water to water heat exchanger, the circulating pump, or the piping/valves. Better get some and keep it handy. December 17, 2014

Rated 5.0 out of 5.0 by Works as advertised! A week before heading out on vacation I discovered a leak in a pipe joint on my boiler. Not having enough time to get a plumber in to repair the problem I tried some plumbers putty and other temporary sealants to resolve the issue. Each of these seemed to slow the leak down, but did not completely stop the problem. With just a couple of days left I decided to give this product a try. I followed the instructions unscrewing the pressure releif valve and pouring the product into the boiler. After reinstalling the releif valve I fired up the boiler. I was stunned to see the leak completely stop within minutes. I held my breath as the boiler pressure rose as this is when the other products failed. No sign of the leak reappeared. I checked the boiler over the next two days and was happy to see that the boiler remained dry and the water level in the boiler remained intact. This is a wonderful product! February 3, 2013
Rated 4.0 out of 5.0 by sofarsogood easy to use took a long time but seems to be working January 27, 2015
Rated 5.0 out of 5.0 by This product works wonders. I had a leak in my boiler and it keep putting out the piolit light, had to do something so I figured I will try this stuff; I am really surprised with the results.It didn't only stop the leak but when it dried it showed the size of of it. I would use this product again if needed to. March 25, 2013
Rated 4.0 out of 5.0 by It plugged the leak I ordered a bottle from Home Depot, but when reading the instructions found out I needed 5 more. I ordered the rest from Lowes, since Home Depot had a huge shipping charge. Maybe it was a mistake on Home Depot's system. Followed the instructions, but isolated each of the 3 zones of my radiant floor to be able to reach 180 F out, 135 F coming back. By the way, I electrically bypassed the burner high limit to keep it going. Recommend getting someone who knows what he/she is doing if your controls don't allow you to safely set 180 F in your boiler. The hotter the better. Then I increased the pressure from 5 to 20 PSI and saw the pressure go down to 5 again. Subsequently I increased it to 25 PSI and witnessed, with amazement, that the hole apparently was closed. I kept it there for two hours at full fire. I told my wife the house was going to get hot. I am glad I warned her, otherwise I would not be writing this now. Report: No pressure loss for the last 24 hours. If it last for the next few winters it would be a huge success. Will see. Good luck to you. April 22, 2014
