It offers the flexibility to cover 5 or 6m applications with one pump. The ALPHA1 is an economic choice, reaching the highest possible energy savings in contrast to older technology fixed speed pumps. This is achieved by its permanent magnet motor technology, which can be as low as 4 watts which can be seen on the LCD power display. The variable speed modulating modes allow the pump to match its performance to the system requirements, helping to reduce noise when thermostatic valves are closing. Noise/heat insulation shells are supplied as standard. This pump has an energy efficiency index of 0.17 and features 3 constant pressure modes for underfloor heating and 3 proportional pressure modes for radiator systems with high flow variation. It also includes an automatic de-blocking function with a robust start-up function and is maintenance-free and low noise due to its canned-rotor design. The compact design allows for up to 6m head.
This guide is for homeowners and HVAC professionals looking to optimize their heating and hot water systems. The Grundfos ALPHA1 circulator offers high energy efficiency and variable speed control, leading to significant energy savings. However, proper installation and system compatibility are crucial for optimal performance. This pump is designed for efficient liquid circulation in heating and hot water systems, featuring a permanent magnet motor for low energy consumption and various operating modes.
