Grundfos ALPHA SOLAR circulator for a high efficiency solar water system.

ALPHA SOLAR is a circulator pump designed for solar thermal systems. It has three constant curve modes, and it is also possible to control the speed using a low voltage PWM signal from a solar controller.

Grundfos ALPHA SOLAR offers very simple installation and a low noise level. This highly efficient and reliable pump is designed to be maintenance-free with durable ceramic bearings and shaft, as well as corrosion-resistant stainless steel components.

Reliable and high efficiency
The PWM signal generates an analog signal using a digital source to control pump speed, performance and to optimize solar collection and ensure minimum energy consumption .

Easy Access
A manual release screw is accessible from the front of the pump.

Remote Troubleshooting
A dry run warning is available as a PWM feedback signal.

Easy handling
Very simple installation, low noise level and maintenance-free.

    5 Stars. There are 5 of us and we are very happy with the hot water. After searching for information for almost a month on low-consumption hot water systems, we decided on b. heat only hot water. Delivery in just 3 days from the web order.

    Delivery was delayed a day due to the height of the package but then everything was perfect.

    Thank you :)
