HEAT4U: Gas Absorption Heat Pump solution for existing residential buildings.

The idea of HEAT4U is to develop a new efficient solutions for energy generation, storage and use related to space heating and domestic hot water in existing buildings.

Residential buildings represent 60% of the building stock and the area where most of the potential to drastically reduce energy use and CO2 emissions lies. New directives push for deep retrofitting efforts, in order to achieve energy efficiency and RES adoption targets for 2020 and beyond.

HEAT4U is one of the most important international research projects in the area of climate change and energy efficiency applied to the built environment. The challenge for HEAT4U is to implement the gas absorption heat pump technology in the area of single-family detached residential homes. What is even more important is the goal of designing heat pumps that can be installed in the existing buildings stock to improve the heating efficiency (49% of the overall energy consumption in terms of primary energy, and 36% of greenhouse-gas emissions).

The final results of the project have confirmed that the absorption heat pump powered by natural gas GAHP is a high-value solution and already in line with the new and future standards for the rational use of energy and renewable energy sources, and fully compatible with the existing distribution networks. The heat pump GAHP can increase by over 35% the energy efficiency compared to the best condensing boilers thanks to the use of renewable energy, with the resulting cost savings and environmental benefits.
