APOLLO HydroMAX 15 — Smarter Heat Transfer, Lower Energy Bills

HydroMAX 15 is a multi-award-winning hydronic system additive independently proven to reduce space heating energy consumption by up to 15%. Compatible with any hydronic heating, chilled loop, or process system containing water or glycol solutions — including boilers, heat pumps, and geothermal systems.

Made & Engineered in England.

Typical Return on Investment 1.5 Years Most installations pay for themselves within 1.5 years — then keep saving year after year.

APOLLO HydroMAX 15 - Up to 15% Energy Savings, Lower Energy Costs, Fast Return on Investment


⚡ Why HydroMAX 15?

Water has naturally high surface tension, which limits thermal contact with heat exchanger surfaces and reduces system efficiency. HydroMAX 15 lowers that surface tension, allowing heat to transfer more effectively — so your system heats up faster, runs shorter cycles, and uses less energy.
