Charging valve unit ACGE pump Grundfos UPM3 Auto L25-50 DN25 fixed value

• Pre-assembled valve unit for solid fuel buffer storage heaters, designed to maintain a high boiler return temperature. An optimal boiler return temperature prevents condensation and boiler creosote buildup, resulting in reduced environmental impact and an extended boiler lifespan. The charging valve unit can also improve stratification in buffer storage systems.
