Energy technology company Oilon and an energy company Helen have jointly developed a heat pump solution that utilizes the property’s waste water as a heat source. In addition, the heat pump installed in the apartment building built in Postipuisto in Pasila, Helsinki utilizes the waste heat and geothermal heat generated from the refrigeration machines and cooling of the Ruokakauppa located in the building.
If more heat is generated in the property than it is consumed, it is delivered as district heating to Helen’s network.
“Not even a joule of energy is wasted in this facility,” Oilon’s business director Martti Kukkola states in the announcement.
Two-way energy production and use aims to renew the heating and cooling of buildings in a more climate-friendly direction.
“Recycling always makes sense, but right now investing in technology that promotes energy efficiency and the utilization of waste heat is more important than ever,” says the manager of Helen’s Solutions and Product Portfolio Development department Sari Mannonen in the bulletin.
According to Kukkola of Oilon, high-efficiency heat pumps play a significant role in this transition.
Wastewater has been used in the past to recover waste heat, for example in the Katri Vala heat pump plant and in several commercial and real estate sites.
The heat pump built in Pasila has also received recognition from the European Heat Pump Association EHPA, which has been awarding the continent’s most innovative and energy-efficient heat pump projects since 2011. Oilon and Helen’s solution won The Heat Pump award in the DecarBuilding series.
