Definitions

  • the present invention relates to an apparatus for the heating of fluids in heating systems and/or in plumbing systems.
  • the hydraulic circuit is split into a first sub-circuit intended for heating radiators, which is connected to a primary heat exchanger, and into a second sub-circuit intended for domestic hot water distribution, which is connected to an additional secondary heat exchanger.
  • the thermal energy generated by such combustion is then used to heat water through the first and the second heat exchangers.
  • the localization of combustion within the combustion chamber does not allow even heat distribution and, therefore, even heating of the water to be delivered.
  • an electric boiler comprises a water tank and a coil consisting of a resistor that, when electrically powered, gives off heat to heat the water inside the tank.
  • a thermostat regulates the water temperature by controlling the turning on and off of the coil.
  • heating the water inside the tank by the electric heating element does not promote even heat distribution.
  • the heating element since it necessarily has to reach very high temperatures, brings the water adjacent thereto to boil, resulting in precipitation of salts. This increases the risk of boiler damage, thus making periodic maintenance operations necessary.
  • the main aim of the present invention is to devise an apparatus for the heating of fluids in heating systems and/or in plumbing systems that enables even heating of the fluid to be distributed.
  • Another object of the present invention is to devise an apparatus for the heating of fluids in heating systems and/or in plumbing systems that will result in greater energy savings.
