The Ecowec wasteHEAT system is a new comprehensive solution for property heating, combining a traditional district heating heat exchanger with significantly enhanced energy efficiency through wastewater heat recovery using the Ecowec hybrid exchanger and a heat pump.
The system can easily be expanded with a cooling unit for summer cooling of the property. It can also be upgraded into a hybrid system integrating various solutions.
The Ecowec wasteHEAT system offers an energy-efficient and intelligent solution for property heating by utilizing both district heating and wastewater heat recovery. The system’s control logic ensures that heat is distributed optimally to various applications, such as underfloor heating, ventilation, heating, and domestic hot water heating during summer, whenever recovered heat from wastewater is available. The system can also be used for summer cooling, significantly enhancing living comfort.
Delivery scope and installation
The system is designed and dimensioned according to the specific heating needs of the property. Delivery includes all necessary equipment, connection instructions, and commissioning support. The installation is designed to be as smooth and easy as possible.

Energy savings and cost benefits
The Ecowec wasteHEAT system enables significant energy savings and reduces the need for district heating in properties. Thanks to wastewater heat recovery, the system efficiently recycles heat back for use within the property. This innovative solution saves both energy and money, making it a sustainable and economically viable option.
System automation
Both the district heating system and the heat pump controls operate independently, with information provided to the building’s automation system. This enables real-time monitoring and optimization, increasing the system’s reliability and efficiency. The control system also ensures that the district heating return temperature remains sufficiently low.
User experiences and reviews
User experiences have demonstrated that combining wastewater heat recovery with district heating is a reliable and efficient solution for property heating. Customers have reported significant savings in energy costs and improved energy efficiency. The performance and savings of the Ecowec wasteHEAT system are easily verifiable, contributing to high customer satisfaction.

Potential for hybrid systems
The Ecowec wasteHEAT system can be expanded into a hybrid system that integrates other energy sources such as energy piles, geothermal energy, exhaust air, and solar energy. By combining different solutions, it is possible to create plus-energy buildings that produce more energy than they consume.
From plus-energy buildings to plus-energy area solutions
The Ecowec wasteHEAT system can also be expanded into large-scale area solutions that combine multiple renewable and waste energy sources, such as energy piles, geothermal energy, exhaust air, solar energy, and condensation heat from refrigeration units. By integrating these solutions, plus-energy buildings and areas can be realized, which produce more energy than they consume. Additionally, the system can supply heat to the area’s heating network or cooling to the cooling network, enhancing its versatility and efficiency.
In collaboration with Nibe
The Ecowec wasteHEAT system has been developed in collaboration with Nibe. Ecowec and Nibe ensure high-quality equipment and technical expertise for the system. This partnership adds value both functionally and economically, guaranteeing customer satisfaction and the system’s long-term performance.
Wastewater heat recovery is the most cost-effective way to reduce the property’s energy consumption. About 30% of the residential building’s annual heating energy consumption goes to heating the domestic water and thereby to the sewer. In energy-efficient class A properties, the share of energy contained in domestic water is more than 50% of the heat balance. It is possible to recover thermal energy from waste water sent to the sewer and use it again with the help of the Ecowec hybrid exchanger.
