1.    Powersource cable 2*2mm2 220 volts next to the returning pumps

2.    Cold WaterSource 1"

3.    Hot WaterLine 1"

4.    Water lineback 3/4"

5.    Exchangepoint in place of boilers and lamps

6.     Source of ventilation (if possible hood)

7.     Chimney exit if there is a chimney

Second: the heaterand the tank:

Is the addition ofa heat exchanger to the central heating system in case there are many bathroomsand kitchens as well as the use of a line due to hot water and the size of theheater is chosen according to the number of hot spots and the number of peopleto determine the capacity of the exchanger Reflex,  which is  German-made andfeatures distinctive insulation to maintain the temperature of water inside foras long as possible to reduce consumption in gas and is made of magnesium forthe heater and bear the coil in it to a temperature of up to 1000 degrees tohelp The speed of heating the water and makes the circle closed between theheater and the  Reflex exchanger.
