1 lb. Boiler Solder (Powdered Stop Leak)

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!

Putting this product into a steam boiler will not only create the worst foaming overcarry you've ever experienced, but will also prime the system. If you do get the product to steam without priming, you will get a very strong burning-oatmeal smell out the vents. Purging the product from the system (as well as the outgoing/return pipes) is going to take a very, very long time involving (in my case) back flushing every return line at the radiator and open a 2" port on the side of the boiler and wand-flushing the internals of the boiler out. If you have a customer that decided to put it in w/o consulting you first..I would say 'no bid' on repairing the situation that unfolds. Again, the solution being either replacement of the boiler (or extreme cleaning) as well as flushing the return lines of loose product. Again, extremely time-consuming and can be messy beyond belief.
