Golden weld heat network

28 March 2019

The green ring road, part of the Dordrecht heat network, has been completed on 28 March thanks to the last - so-called 'golden' - weld. The 'golden weld' is special because it cannot be controlled from the inside op the pipe. It is precisely for this reason that applying it requires even more attention and precision than regular welds.

The 'golden weld' was symbolically sealed on 28 March by alderman Rik van der Linden at the A.Hak worksite. With the completion of the underground ring road the Dordrecht heat network can continue to grow. Rik van der Linden calls it a new milestone in making the city more sustainable. ‘Our municipality is leading the way with the construction of a heat network in urban areas. We are very proud of that'.

The heat network is more than 22 kilometres long and has been built in approximately six years. Arjan ten Elshof, director of Renewable Energy at HVC, thanks all parties who have contributed to this. ‘Not only the people who thought up the main grid inside, but especially the people who built the heat pipes outside. It is a tough job, sometimes in difficult circumstances. I have a lot of appreciation for that.’

In Dordrecht about 4,700 house equivalents are now connected to the heat grid. By the end of 2019 there will be about 6,000 of them. Ten Elshof: ‘This will reduce CO2 emissions by 6,000 tonnes. This can be compared to the CO2 reduction of more than 35,000 solar panels.’
