6.5.1 Installing a DHW tank
The DUAL CLIMA R heat pump may include (optionally) in its installation a tank for the production of
domestic hot water. In the offering of aerothermal accessories, DOMUSA TEKNIK offers a wide range
of DHW tanks specially designed to be combined with the DUAL CLIMA R heat pumps ( Sanit HE ,
BT-Trio and BT-Duo HE lines). The hydraulic installation of the tank must be made by qualified
personnel, subject to the applicable installation legislation and the attached instructions of the tank.
To combine an DHW tank with the heat pump, insert the "DHW TANK SENSOR" supplied with it into
the tank sensor housing. In addition, a 3-way diverter valve ( G2 ) must be installed between the external
machine and the DHW + heating/cooling installation, by means of what, the electronic controller diverts
the water from the heat pump to the DHW production or to the Heating/Cooling installation, depending
on whether there is demand for DHW.
Dc: Dual Clima R heat pump.
Ac: Sanit HE tank.
Sa: DHW tank sensor.
G2: 3-way diverter valve.
E1: DHW backup resistor.
Ic: Heating/Cooling installation.
In addition, optionally, a backup heater (E1) can be installed, by means of what DHW temperatures
higher than 50 ºC can be obtained.
As alternative to the backup heater, DUAL CLIMA R heat pump optionally allows the connection of a
conventional source of energy (as a gas boiler, oil boiler, etc.) as backup for DHW production, by means
of the same electrical connection E1. For it, the DHW tank must be provided with an auxiliary coil
exchanger and/or any intermediate system of exchange that allows the hydraulic connection of the
above mentioned backup source of energy. Within the range of accessories for heat pumps,
DOMUSA
TEKNIK offers the range of DHW tanks Sanit HE DS , which incorporate an auxiliary coil exchanger
specially designed to be combined with DUAL CLIMA R heat pumps.
Dc: Dual Clima heat pump.
Ac: Sanit HE DS tank.
Sa: DHW tank Sensor.
G2: Diverter 3 way valve.
E1: DOMUSA TEKNIK’s backup boiler.
Ic: Heating/Cooling installation.
To perform the electrical installation of the DHW tank sensor, the 3-way valve ( G2 ), and the backup
heater or boiler ( E1 ), read the
"Electrical Connections"
section of this manual carefully.
