Note: The extensive use of the electric heater leads to higher electricity consumption
and it may lead to high electricity bills. The operation with heat pump normally con-
sumes more than 3 times less electricity than the operation with electric heater. The
energy released to the condenser (2-3) is, in fact, the sum between the free energy
extracted from the air in the evaporator (1-4) and the energy supplied to the compres-
sor (2-1). On average, the energy absorbed by the evaporator is more than double of
the energy used to run the compressor.
1.2.4. Safety instructions – Cooling circuit
• Only skilled and trained technicians shall carry out repair and service of the heat
pump circuit.
• Before opening the cooling circuit, discharge the refrigerant to a level that allows
safe working conditions.
• The refrigerant can be toxic if inhaled or if in high concentrations.
• Special attention should be given if the work is carried out with an open flame.
