1″ MCCS Anti Condense Pump Pack Set at 60c with W7 3 Speed Pump

The 1″ MCCS Anti-Condensation Pump Pack is a compact thermal loading unit engineered to safeguard solid fuel boilers, biomass systems, and log burners against cold return water temperatures. Factory pre-set at 60°C, this mixing pump pack automatically recirculates hot flow water back into the boiler return until the system reaches optimal operating temperature—preventing thermal shock, flue gas condensation, creosote/tar build-up, and internal boiler plate corrosion.

Equipped with a reliable W7 3-speed circulation pump and standard 1″ (DN25) female BSP threaded connections, this unit ensures efficient heat transfer into buffer tanks, thermal stores, or central heating circuits while maximising combustion efficiency and boiler service life.

Key Benefits & Features

• Prevents Boiler Condensation & Tarring: Keeps boiler return water above 60°C to eliminate cold-spot condensation, reducing flue tar deposits and extending boiler longevity.

• Pre-Set 60°C Thermostatic Element: Factory-calibrated thermal valve modulates flow automatically to maintain consistent internal boiler temperatures.

• Standard 1″ (DN25) Connections: Fits seamlessly onto standard 1″ female BSP heating pipework and thermal store manifolds.

• W7 3-Speed Circulation Pump: Features selectable 3-speed settings to fine-tune system flow rates and hydraulic performance.

• Accelerates Boiler Warm-Up: Rapidly brings the boiler up to working temperature to optimise fuel burn efficiency and reduce emissions.

• Compact Pre-Assembled Package: Factory-tested unit simplifies installation onto solid fuel boilers, wood pellet burners, and thermal storage loops.
