The boiler heat pump produces hot waterA compact system for domestic hot water preparation is represented by boiler, heat pump, air (Series Air Combo).

The heat removed from the air, enhanced by the heat pump, is directly transferred to the accumulation of hot water below.

The required air can be sucked from the local installation from a local neighbor or directly from outside through a pipe: in the design phase it must be ensured that the air used is within the operating range of the heat pump (- 10 43 ° C ° C) and is not exhausted from too dusty or polluted environments.

The passage of air through the evaporator produces the cooling and condensing the moisture contained: occurs therefore a dehumidification that can be exploited advantageously in humid environments.

Lend themselves to the placing of these heat pumps, local as:

  • laundry / drying room;
  • cellars / handouts;
  • unheated rooms;
  • equipment rooms,

provided it is ensured minimum volume of at least 30 m3.

Connect the kettle to heat pump

The contribution given by the refrigerator operation of the heat pump unheated environment must be properly considered so that the heat dissipation does not spread to neighboring environments: a good indication is to insulate the walls of the boundary between the local installation and local of consumption.

The cooling of the installation, you avoid channeling heat pumps and then working directly with the outside air.

For the sizing of these units, as they are characterized by a power and an accumulation set, you can follow as a criterion to cover the estimated daily requirement. Based on the models Available, is a table indicative of sizing, for the residential sector:

Number of users Heat pump
1:4 Air Combo 200
4:8 Air Combo 300

For different applications from residential should instead assess the requirements according to the type of user: the needs more can be covered with multiple drives installed in parallel Air Combo.

In rooms with intended use different from the housing in which are present of the flow of air extraction (fraction of renewal expelled, air extraction kitchens of restaurants, etc..), The air extraction becomes an effluent energy usable by heat pumps for domestic hot water production.

The units shall be accompanied by supplementary electric heaters that can intervene with emergency function and are designed to connect to alternative energy sources such solar thermal plants and wood / pellets.
