Gebwell G-Power® district heating substation 

G-Power Easy district heating substations are designed for connecting detached, semi-detached and small row 
houses to district heating. G-Power Easy is suitable for newbuild as well as renovation projects and it can be 
connected to radiator, underfloor and air heating. G-Power district heating substation is equipped with brazed plate 
heat exchangers. 

G-Power district heating substations are available with 2 and 3 circuits. Two-circuit-substations have control circuits 
for producing hot water needed for heating domestic hot water and for heating network. With third control circuit 
the damp spaces like bathroom or washroom all year round apart from the heating needs of other rooms. 

G-Power district heating substation models: 

 

2-circuits: 

G-Power 2/100, 2/150 and 2/200:

 domestic hot water circuit and one heating circuit 

 

3-circuits: 

G-Power 3/100:

 domestic hot water circuit and two heating circuits 

Model designation: 

2/3 indicates the number of control circuits, 100-200 indicates the power class (100 = detached houses, 150 = 
detached houses and 200 = detached houses / small terraced houses) 

District heating, inlet 

Piping to transfer the heat from the energy company to the consumer’s district heating substation. 

District heating, return 

Piping to transfer the heat from the consumer’s district heating substation back to the energy company. 

Heating, supply 

Piping to transfer the heated water from the heat exchanger to the radiators, underfloor heating or air supply 
unit. 

Heating, supply water temperature sensor 

The supply water temperature sensor is the part in the control or measurement equipment for measuring the 
temperature of the supply water. The temperature sensor is on the surface of the pipe, and it produces the 
measurement values for the controller. 

 

G-Power 2/100, 2/150 and 2/200 

TE2A 

G-Power 3/100 

TE2A and TE3A 

Overheating protection for underfloor heating (pump stop thermostat) 

Overheating protection protects the underfloor heating, e.g. by stopping the circulation pump in the event of 
a malfunction of the control unit.
