Press release from 4DH conference:

Real district heating systems

The winner of the Senior category, Martin Crane, is owner and Managing Director of the UK district heating and energy efficiency consultancy Carbon Alternatives. He won the 1000 euro prize sponsored by Danfoss.

“Our senior winner is a person working close to reality. The committee was impressed by his presentation of a substation test ensuring performance in real district heating systems,” said Sven Werner, Professor at Halmstad University in Sweden and part of the judging panel.

Martin Crane’s presentation was about the development of the UK Heat Interface Unit (HIU) testing regime which he worked on together with energy consultants Fairheat, inspired by a Swedish test and modified to British conditions.

He said: “It’s very flattering to be selected for this award by such an esteemed group of the world’s experts in energy efficient district heating. Over the years I have learnt much from their research. It’s great that they value the HIU testing regime we have developed in the UK. Many thanks to the DECC/BEIS for funding the research.”

“The test has already got HIU manufactures improving and retesting their products to achieve lower return temperatures under the real world test conditions. The test has also prompted the overdue consideration of how the efficiency of DH network can be achieved in practice, specifically consideration of standby performance. The test, through the calculation of a volume weighted return temperature (VWART) for each HIU tested now provides a more robust route to specifying a HIU that will be efficient in operation and puts, long absent, focus on the correct setup of the radiator in the heating system.”
