Dutch city’s heat network expanded

The Dutch city of Roosendaal will se an expansion of an innovative, low-temperature district heating network.

The residents of the Nieuwe Wipwei district in Roosendaal will benefit from the low carbon heating as the city continues to realise its sustainability targets. Waste heat from the local SUEZ waste processing plant will be used to provide the heat.

Sustainable Energy Company Roosendaal took the initiative to implement a Smart Climate Grid for the supply of heat to a local college and residential district in 2012. To this end, it makes use of clean waste heat of 42° Celsius from a local waste processing plant operated by SUEZ – energy that would otherwise be lost. Already, this has cut the college’s energy bill by 50%. The connection of the new residential quarters to this unique district heating network marks an important milestone: heating individual homes based on the only low-temperature district network in the Netherlands.

By using low temperature (LT) waste heat, heat loss is significantly lower while ensuring a much higher thermal energy yield.
In order to minimize disturbance for current residents, the partners took up the challenge to implement the entire network within 3 weeks, while at the same time securing a future-proof solution. The Cradle to Cradle Certified™ Silver Flexalen piping system, delivered with plug-and-play Flexalink house connections proved to be the ideal fit.

The expertise and a structured approach also proved to be highly effective in the rapid installation of a reliable Low Temperature (LT) network, whereby disturbance to the local environment was kept to a minimum.
