The integration of heat pumps (HP) into existing buildings involves potentially major technical transformations. In addition, this transition often uses the new heat pumps at high temperatures (55... 60°C), which reduces their performances.
Heat 4T° is a patented control switching system that allows the entire existing chilled water distribution network and its terminal units to be used as a low-temperature heating network.
Replace your chiller with a reversible hot/cold model
