Installing an ALPHA1 pump will reduce power consumption considerably, lower noise from thermostatic valves and similar fittings and improve the control of the system.

Advantages:

• High-efficient motors EuP 2015 ready.

• Suitable for installation in existing systems.

• Low-noise operation.

• Built-in electrical and thermal protection of the pump.

• Simple setting and operation in a very compact design.
• Plug and play with patented cable plug for safe and easy connection. 

ALPHA2 is the best pump to withstand the tough conditions in a heating system, and with four newly added features, it just got even tougher:  

Robust start-up:
Shakes free any impurities before the pump starts at the beginning of the heating season.

Summer mode:
Adjustment of the pump’s performance in the summer to the warmer temperature outside – giving customers extra energy efficiency

Magnetite resistance:
Ensures that no small pieces of metal get stuck in the pump’s vital parts when they are magnetised

Dry-running protection:
Makes sure the pump never runs without liquid in the system

Add to that unrivalled energy efficiency, easy installation and the fact that ALPHA2 covers both your heating demands and up to 90 % of your air-conditioning and cooling demands.

The GRUNDFOS ALPHA2 is suitable for:

• Systems with constant or varying flow
• One pipe systems
• Two pipe systems

• According Ecodesign requirement January, 2013; EEI ≤ 0.23
• Internally self-controlled circulator
• Integrated differential-pressure control enabling adjustment of pump performance to the actual system requirements.
• 5 Configuration Options:
  highest proportional pressure curve (default),
  lowest proportional pressure curve
  lowest constant pressure curve
  highest constant pressure curve
  constant curve speed I, II and III
  
• ALPHA2 L can run on as little as 5 W

The ALPHA3 is our newest circulator for domestic buildings. It is of the renowned Grundfos quality and guarantees easy installation, world-class energy efficiency and reliable operation in the toughest conditions. For the ultimate benefits of the ALPHA3, however, installers need two other components – the ALPHA Reader and the Grundfos GO Balance app. Together, the state-of-the-art ALPHA3 system helps installers complete a hydronic balancing incredibly fast and accurately.

Features and benefits

• Hydronic Balancing
• No blockage
• Best in class efficiency

Benefits of hydronic Balancing:

• Savings on heating bill between 7-20 %*
• Lower return temperature in the system
• Lower noise in the heating system

A brand new, low noise permanent magnet motor allows the energy
consumption of the COMFORT PM range to be reduced to as little as 5-8.5 W.
Combined with the intelligent AUTOADAPT function this sets new standards for energy-efficient hot water recirculation in private homes.

Thanks to the new high efficiency permanent magnet motor the COMFORT range now features two new variants for hot water recirculation. With an energy usage of only 5-8.5 W both the COMFORT pump with AUTOADAPT and the fixed speed COMFORT B pump can significantly reduce the power consumption. In fact, the electricity costs of operating in AUTOADAPT mode requires a mere 1-2 €* per year. Compared to conventional pumps that run continuously this equals a cost reduction of up to 96 %. Moreover, heat energy savings amount to as much as 48 %.

The AUTOADAPT principle The principle of the AUTOADAPT function is really very simple.
In the course of only a couple of weeks the COMFORT pump learns the hot water consumption pattern of the household and adapts to it. The stored data ensures that the pump runs only when required – which significantly cuts back on both water and power waste. Should the consumption pattern change, e.g. during holidays, the COMFORT pump with  recognises the standstill after 24 hours and automatically adapts to holiday mode. On the return of the occupants, the intelligent pump will automatically resume the same  consumption pattern as before the holiday. Consequently, the access to instantly hot water is never jeopardised.

Minimise water waste
All COMFORT pumps – with or without the AUTOADAPT function – combined with a return pipe deliver instantly hot water all over the house. This eliminates the expensive – and annoying – wait for the water to get warm and reduces the annual consumption of domestic water. The results are lower costs while still ensuring the comfort of instantly hot water.

Easy installation
The COMFORT BA pump with autoadapt and the continuously
running COMFORT B pump are equally compact and designed to greatly facilitate installation – even in confined spaces. Both featuring the renowned ALPHA plug all that is really required is to connect the plug and start pumping.
