1. General What is warm water heating? 2 With this definition, all systems are included, where: • warm water has a temperature less than 100°C • generated in a central place, • is used to transport heat in closed loop systems • to individual consumers in one or more buildings. The range of these…

2. Heating

The pumps are necessary to make the water in the system flow. Two main factors are important for dimensioning a pump: • The discharge flow. We have to use the maximum probable flow. • The delivery height, which is necessary to override the flow resistance, caused by the pipework and the consumption.…

2. Heating

Manifold with differential pressure (4.2.1) Function In systems, where a differential pressure between the flow line and the return flow manifold is required, it is necessary to have a pump in the loop between the heat generator and the manifold. The function of that pump is to override the flow…

2. Heating

Manifold without differential pressure (4.2.2) Function 2 In situations with a low distance between the heat generator and the manifold, we can renounce using a main pump. In this case the pumps of the control loops have to override the flow resistance of the pipework of the control loop, the…

2. Heating

One pipe system (4.3.1) Function In radiator systems the water passes the heating surfaces which emit the heat to the surrounding area. Thereby the water cools down. The output power of a radiator is depending to the flow line temperature and the size of the radiator. In one pipe systems the return…
