Seems to be working so far
By Heating guy
from Portland, OR
Comments about 1 lb. Boiler Solder (Powdered Stop Leak):
I have a client with an old iron pipe in/under concrete slab, floor heating system. They had developed a significant leak (based on the rate of pressure drop) but its location was not apparent. I suggested that a leak fix approach might buy them some time and it was cheap enough that even a 50-50 chance was worth a try. If it didn't work, then time for the IR camera and some concrete cutting.It has been two weeks since I tried it and the homeowners have told me it seems to have worked! Even if it just gets them through the heating season definitely worth the money.Suggestions:This is a dry product that you mix with water to make a slurry before adding to the system. I tried to "pour" the mixture in as the directions recommended but the pipe I had available for this was only 1/2" and the mix proved a bit too thick. After fiddling with it, I managed to pump it in with a utility pump (an old Taco 007 circulator) into the suction side of the system pump. This worked pretty well. I recommend based on my experience that you keep the system circulator running while you add this otherwise it seemed to stay in one spot and not mix in. With both pumps running, it added in and circulated and the heat moved normally. Prior to that, when I tried pouring it in, it seemed to block up the water passages (likely because I had it too thick) and it took a while of working the pumps and valves to get it broken loose. Once it did, no further issues.
Bottom Line Yes, I would recommend this to a friend

PexSupply saved my family
from Sandy victim and 2/9/2013 survivor
Tool used: Rubber hose and a clear 2 liter plastic soda as a funnel.Use steam boiler cleaner to remove rust. Use a good mask and the boiler is OFF all the time. Let the boiler leak by itself till it stop to the level of the leak. Drain the boiler to a five gallon container. Warm the boiler like 3-5 minute run. I used 2 lbs of Boiler Solder. Use several empty 64oz plastic do the mixture with warm water until it is not slurry. The higher the funnel above the water level, the faster and less clogging. Keep stiring the contents well. Flush w/ clean water if it happens. And Good luck.The water has to be above the leak spot anyway.
BOILER SOLDER FIXED OUR LEAKY FURNACE!
from DAGGETT, MICHIGAN (Upper Peninsula)
Our last outdoor furnace was installed in January 1999, a HEATMOR. A furnace with an outstanding reputation. Stainless steel firebox. This furnace is not pressurized as some are. It holds 90 gallons of water and the first few years we added a few gallons of water every 3 or 4 weeks. But, after throwing big heavy chunks of wood into the firebox for several years it started taking more and more water to keep it up to the desired operating level. I imagine I cracked a weld by being a little forceful as I threw in the wood chunks. I'll take the blame. This became a big concern and we examined all the pipes and plumbing to no avail. It got so bad the last couple of years that we would have to open the valve and add at least two minutes worth of water (probably 8 to 10 gallons) EVEERY 2 DAYS! I started researching products on the internet and came across this one called "Boiler Solder." Being desperate, I ordered 3 lbs. and within 3 days we received the box and immediately read the directions and mixed the product with hot water and introduced it into the furnace. This furnace is in a shed on a cement floor, with an entire winter's supply of wood. We never noticed a puddle on the floor around the furnace, but obviously it was leaking as the ashes began to get wetter and wetter. It has been 3 weeks tomorrow since I added water and the gauge still registers in the safe operating level. Thank you HERCULES for developing a product to stop serious leaks in heating systems. TRULY A MIRICLE!
We have 2 Peerless sectional boilers that developed large leaks. We only need the boilers for this season as they will be replaced in the summer of 2013. We followed directions and the boilers sealed pretty much immediately. Water and pipe hammer caused one of the boilers to leak again but it sealed back up.
