This project aims to accelerate the energy transition by developing an innovative heat pump system for non-residential construction: the Turbo-Combi-Buffer (TCB). This system offers a compact and efficient solution for space heating and hot water production, with the aim of reducing the use of fossil fuels and reducing CO2 emissions, as well as reducing material consumption and reducing the installation footprint. The TCB is a compact and modular buffer tank with smart temperature zoning, allowing heat to be stored and used more efficiently. This results in a flexible and sustainable alternative to conventional heating systems. The project is carried out by a consortium consisting of Conico Valves BV, NRGTEQ). • Conico Valves BV leads the project and focuses on the development of valve technology within the TCB. • NRGTEQ integrates the TCB with a heat pump and validates its performance through extensive testing.
