The role of pumps in delivering energy savings
Published:  October 2007

There is very little to be gain by improving the efficiency of pumps to reduce their energy consumption. Much more can be saved — about half — using speed control and the better design of systems, as John Veness explains.

Grundfos fire sets for projects in the UK are all built and test at its Leighton Buzzard headquarters.

Countering the fire risk
Published:  October 2007

It is over 60 years since a death was recorded in the UK in a building with a working sprinkler system. Glynn Williams cuts through the complexities of using pumps to protect against the risk of fire.

Wilo shows the way to reduce pumping costs
Published:  October 2007

Replacing pumps in 12 plantrooms at Derriford Hospital in Plymouth with equivalent pumps from Wilo’s energy-efficient range will reduce energy consumption by £70 000 a year — a useful dent on the electricity bill of over £1 million a year.

The third stage of the Grundfos Energy Project to encourage the use of more efficient pupmps is under way.

Grundfos energy project enters its third phase
Published:  October 2007

Grundfos is moving into the third phase of its project to increase awareness of how using efficient circulators can significantly reduce carbon-dioxide emissions. The project started in 2005 with the launch of the world’s first A-rated domestic circulator — the Alpha Pro.

How Grundfos aids pump selection
Published:  October 2007

To help customers decide which pumps would best suit their needs, regardless of the application, Grundfos provides a range of selection tools —which have become industry standards. These aids are constantly reviewed and updated to keep them relevant.

parallel pumping

Parallel pumping enables installed power to be halved compared with full duty/standby — and even greater savings can be achieved by controlling pumps to deliver the required flow.

Delivering energy-efficient pumps
Published:  October 2007

Designing systems with duty and standby pumps that can both meet maximum demand is must not efficient. Wayne Rose explores other approaches.

System responsive — new circulators from Smedegaard Pumps automatically adjust to the required duty in heating systems fitted with thermostatic radiator valves.

Smedegaard enhances the efficiency of circulators
Published:  October 2007

Smedegaard has developed a range of electronic energy-saving circulators that use up to 60% less energy than a standard pump.

The world's most energy-efficient small circulating pump — the Wilo-Stratos ECO uses just £7.50-worth of electricity in a typical single-family house [in Germany].

The world’s most efficient circulator?
Published:  October 2007

The Wilo-Stratos ECO high-efficiency pump has been given an 'excellent' rating by the German consumers’ association Stiftung Warentest. It came top in tests as the best in energy efficiency and ratio of price to performance compared to all other small circulating pumps.

On a mission to save energy
Published:  October 2007

Lee Tebbatt explains how variable-speed pumps very quickly repay their extra capital cost in vastly reduced running costs.

BACnet-capable drives speed commissioning at Blackburn Hospital
Published:  October 2007

Over a hundred HVAC drives with native BACnet capability have been installed in the new Blackburn Hospital to control water pumps and motors for air-handling units. One of the key benefits was a significant time saving during commissioning.
