Sustainable heating supply for Lalandia

New heating system in the new Lalandia

Ringkøbing-Skjern Forsyning will establish a heating system in the coming Lalandia in Søndervig, which taps energy from drinking water as it passes through the drinking water pipeline from Ringkøbing to Hvide Sande and Holmsland Klit.

Sweco has been chosen as the developer consultant to Ringkøbing-Skjern Forsyning and the new heating system, which is an alternative solution not previously seen in Denmark on this scale.

Sustainability and economics

The plan for the new Lalandia is to use the 7-9 degree drinking water in a heat pump to heat the water in the tropical water park, and to ensure that guests remain warm in the activity centre in the 10,000 sqm amusement centre.

Ringkøbing-Skjern Forsyning came up with the idea for the solution. Sweco is responsible for equipping the plant and performing the calculations necessary to implement the solution.

Innovative solution

Cooling the drinking water down to about 3 degrees allows up to 1.1 megawatts of energy to be extracted. With the help of a heat pump, this can be used to heat water up to the 65 degrees that Lalandia needs to heat the water park and pools.

The heat pump is expected to meet most of the water park’s heating needs. At peak times, supplementary heat will be supplied from accumulation tanks and a boiler powered by natural gas.

This innovative heating solution means that energy from the drinking water will heat the entire new Lalandia – so visitors can look forward to a more sustainable dip in the water.
