Grundfos Comfort System hot water now

The Wait Is Over
Save Water Now!
The average home wastes over 31 gallons a day and over 11,000 gallons a year waiting for hot water. That’s not just wasted water, that’s wasted money and wasted time. But you don’t have to take it anymore.
The Grundfos Comfort System pumps hot water through your existing pipes, so hot water is never wasted and comfortable water is always at hand – in an instant.

QUICK PERFORMANCE RANGE TECHNICAL DATA

MEET THE MAGNA
The new MAGNA variable-speed wet rotor circulator from Grundfos® is powerful, reliable, intelligent, and energy-efficient.

MAGNA delivers plenty of edge by utilizing a permanent-magnet rotor, a revolutionary design pioneered by Grundfos® .

It’s easy to install, simple to operate, and a good choice for the replacement market. With these features and more, MAGNA is the smart choice for your pumping application.
> Integrated frequency converter ensures maximum efficiency during operation
> Patented AUTOADAPT function is the “brains” behind the operation
> Speed-controlled for heating systems
> Short flange-to-flange length
> Proportional pressure control for maximum energy savings
> Optimized sizing, installation, and operation
> Low noise level
> Flows from 10 to 170 gpm
> Plug-and-pump = simple to install
> “Green” conscious and environmentally friendly
> Highly efficient pump and motor
> Available in three models in cast iron or stainless steel construction

Magna Series Variable Speed CirculatorsCOMFORT OR EFFICIENCY?
With MAGNA, you don’t have to choose. The patented AUTOADAPT feature is unique to Grundfos® and is the crowning glory of MAGNA.

Call it the brains behind the pump’s operation: it analyzes your heating system, learns what works best for your application and changes the settings accordingly.

AUTOADAPT works behind the scenes during all stages of the pump’s life cycle. It gives you simple and accurate specification, easy installation, reliable operation, increased comfort, and continued energy savings.

The AUTOADAPT function regularly adjusts the proportional pressure and automatically sets a more efficient performance curve whenever possible. It never sacrifices comfort for efficiency, and the balance is always right.

With AUTOADAPT, the MAGNA isn’t just smart, it’s intelligent.

PROPORTIONAL PRESSURE CONTROL WITH AUTOADAPT
Groundbreaking work by Grundfos® led to the discovery of proportional pressure control. In pumps using this principle, the differential pressure across the pump is automatically adjusted to match the flow.
When the flow falls, so does the pressure required, which results in a corresponding reduced load on the motor − along with reduced energy consumption.

Things get even better when you add the AUTOADAPT function.

At start-up, the MAGNA operates with a lower differential pressure than other comparable units (shown by the AUTOADAPT factory setting line).

As the flow increases, the pump pressure follows the line for the AUTOADAPT factory setting until the pump operates on the maximum curve, continuing downward until it reaches the required flow.
When the flow is subsequently reduced, the AUTOADAPT function ensures that the operating profile doesn’t simply return to the original curve − it actually sets a new, lower pump speed (n=new) that results in even greater energy savings!
