4. Recommendations
4.1 The cold water piping should withstand pressure of 1000 kPa. The hot water piping should withstand
temperature of 95
o
C at pressure 1000 kPa.
4.2. The cold and hot water piping should be well insulated to eliminate heat losses and prevent as possible
freezing. The insulation material should withstand weather conditions like rains, snow and solar irradiation.
4.3. The system should be protected always with antifreeze liquid as supplied by the company to prevent
from frost.
4.4. On the hot water supply piping, install a reliable thermostatic mixing valve set at 55
o
C to prevent higher
temperature hot water to reach the consumption points.
4.5. The system may only be installed in locations with lower values of s
K
(snow load) 0.64m and v
m
(average
wind velocity) 97.2km/h
4.6. The required solar irradiation for which overheating will happen is shown on the table below. The system
should not be used in climate zones with higher irradiation values than these.
