The Aquajoy GPM25-4-130 is a next-generation pump for circulating water in heating, underfloor heating, and hot water systems. It evenly distributes heat, maintains pressure, and helps maintain a comfortable temperature in your home. It connects to a boiler, heat pump, or solar system.

The pump saves energy thanks to automatic speed control. PWM control allows the pump to operate synchronously with the boiler, heat pump, or controller—the speed changes based on their signals. Night mode reduces speed when the temperature is stable. This results in smoother heating and lower costs.

The compact design makes installation and maintenance easy. The LED display shows power, active mode, and warnings, making operation monitoring simple.
