This stuff really works
from Nitro, WV
Comments about 1 qt. Boiler Liquid:
I have owned an outdoor wood burning furnace for more than five years. I love the engineering. However, I was talked into buying "an upgrade" stainless steel "never rust" boiler. Don't do it. What I received was a 409 SS ferritic steel that is the lowest grade of SS and corrodes with a passion. However, it is very difficult for the average welder to weld it so it won't leak. Combine the corrosion issue (worse than mild steel) and lack of being able to weld it to patch the leaks and you have an expensive paperweight. Thanksfully, I have used Hercules Boiler Liquid for several years and it absolutely works without plugging up the rest of the system or interfering with the heat exchangers. The price is right, the shipping is fast, and it works, you can't beat it.
Bottom Line Yes, I would recommend this to a friend

I had a couple of unions that would not stop dripping. This was an inexpensive way to correct the problem.
What a life saver!
By Joe the Accountant
from Chillicothe, OH
Very easy to apply. Works almost immediately with super results. I would recommend this to anyone with a leaky boiler as mine has to eventually be replaced, but I will be able to make it through another winter season and be able to save up for the replacement cost between now and next winter. It truly is a miracle!
My boiler was leaking bad and will still need to be replaced but this product sealed the leak and we should get another season out of the boiler. Unbelievable!!! It's been in the boiler one month and no leaks.....wow!

from Miami, Oklahoma
Worked great, sealed the heat exchanger leak on my hydropulse boiler. Hope to finish this heating season before replacing the boiler this summer
Does exactly what they claim!
from Dublin, Ireland.
We had a problem with an old boiler corroding and developing leaks. Two bottles of boiler liquid plugged the holes and the boiler is working more efficiently than I can ever remember. As we are expereincing the worst cold snap in 48 years here, plumbers were in high demand and none were available to sort out our problem. Being able to fix the boiler so simply was a great relief.
