From the beginning to the end

Benefits at a Glance

  • Most compact design
  • Reduction in the formation of legionella by removal of the central hot water tank
  • The lowest heating overtemperatures are sufficient to achieve the desired hot water temperature and high degree of system efficiency
  • Simple controller technology
  • Best possible integration of alternative energy sources through unlimited expansion of the buffer storage volume


Delta‘s fresh hot water systems are used to generate domestic hot water by means of heat exchangers. They are ideal for replacing central hot water tanks (boilers) with energy-efficient buffer storage heating systems and thus for allowing the integration of alternative heating sources such as gas, oil and solar thermal energy, among others.
