Thermo System Design

Domestic

For a typical domestic application, 40m of pipework is required. This is either with a loop around the building or by a meander pattern. The optimum pipe diameter for air flow rates of up to 300m3/h is 200mm.

Commercial

On commercial applications, it is usual to use a Tichelmann layout. This is a self-balancing system: whichever path the air flows, it travels the same distance, balancing the pressure losses.

Usually DN 200 - 250 pipe is used for the heat transfer and DN 500, 800, 1000 or 1200 is used for the distribution pipe. The required air flow dictates the optimum pipe diameters.
