Best practices examples

Austria

  • “Hot Ice Wize” is focused on the use of latent heat with two ice storages and two heat pumps in combination with unglazed solar collectors and a PV system. It is designed as a pilot project for local heat supply. (more)

France

  • A new built private housing is located in  Marseille, in the South-East of France.  The hot water production is arranged by a solar heat pump. For this installation, climate and sunshine are very favorable. Thus, solar panels are installed on the building roof. (more)
  • The district heating system, specific to this eco-district in Roquebrune Cap Martin (Nice) is quite innovative. It is based on the treated water rejected by water treatment plant located 500m far from the ecodistrict. This water is used as the cold source of 8 heat pumps for DHW production and 5 heat pumps for heating and cooling. (more)
  • In Soissons, heating is supplied by a renovated district heating grid connected to a wood-fired heating plant. The DHW production was ensured by individual electric water heaters until now. The replacement of these by a collective heat pump induces a 50% reduction on the electric bill due to DHW production. (more)

Germany

  • Over a net floor area of 3248 square meters a heat pump cascade system provides warm water, pleasant room temperatures and enough energy for the catering business on the ground floor of the new holiday home Boarding House Potsdam”. (more)
  • Between 1881 and 1966 children were taught inside this old school building in Kempen, which is now listed. In the meantime, the building served as a church, community administration and youth hostel. In 2008, the house was finally rebuilt by its new owner into a multi-family house with five residential units. After the existing building had been heated over the years with an oil heating and district heating, the decision was made to use a heat pump as an environmentally friendly solution.
  • If former industrial and commercial areas are overbuilt, entire districts are often created in a very short time with a distinctive atmosphere and modern flair. This is also the case in the Düsseldorf district of Derendorf, where the discarded freight yard makes way for the “Neues Düsseldorfer Stadtquartier”, which heavily relies on heat pumps.

Switzerland

  • The project in Daru, Geneva concerns the replacement of an existing gas heating system by a hybrid HP+gas solution in an existing multifamily building. With the goal of having the maximum annual heat production from HP origin, six air/water heat pumps were implemented on the rooftop. (more)
  • The project in St. Julien, Geneva concerns the replacement of an existing oil heating system by a HP only solution in a multifamily building. With the goal of having the total heat production from HP origin, two air/water heat pumps were implemented on the rooftop. One of the previous fuel oil boilers was kept for back up. (more)
