OATEY 35206 – Frequently Asked Questions
1) What does Hercules boiler and heating system cleaner actually do in a hydronic loop?
Oatey's Hercules 35206 is a liquid cleaner and corrosion preventative treatment for boilers and hot water heating systems. It cleans the loop, protects against corrosion, frees and lubricates zone valves, and contains silicone that lubricates pump seals. It also carries an anti-foam agent to help stop priming and foaming, which is what helps keep the boiler running at efficiency.
2) We have a steam boiler that keeps surging and foaming at the water line. Is this the right product?
Yes, that's a listed use. The Hercules 35206 treatment carries a special anti-foam agent to help stop priming and foaming, which is the usual cause of an unsteady water line and carryover in a steam system. It also cleans the system, which is where the oil and sludge causing the foaming normally sits.
3) Is this a powder or a liquid I pour into the system?
Liquid. The 35206 Hercules treatment is a pourable yellow liquid, so it goes in through a fill point or feeder without having to be dissolved first like a powdered cleaner.
4) Will this help with a zone valve that keeps sticking?
That's one of the stated jobs of the Hercules 35206 treatment: it frees and lubricates zone valves. It's not a substitute for replacing a failed valve body or actuator, but on a system with sediment and scale binding the valves it's the treatment to run before you start swapping parts.
5) My circulator pump seals keep drying out. Does a boiler cleaner make that worse?
Not this one. Oatey's Hercules 35206 includes silicone specifically to protect pumps by lubricating the seals, so it's formulated to treat the loop without stripping pump seals the way an aggressive straight cleaner can.
