4.7.3 Hydraulic integration Dimplex solar cylinders SCx
Should the cylinder range of 175 to 305 litres not be sufficient, any number of cylinders
can be connected in parallel or in series to achieve higher storage volumes. The follow-
ing should be observed when connecting the cylinders:
- each cylinder must be equipped with its own safety equipment as part of the scope of
delivery
- each cylinder must have its own save discharge in accordance with building regula-
tions
- connect the cylinders on the potable and energy supply side in series when an even
demand is required over a period of time
- connect the cylinders on the potable and energy supply side in parallel when peak
demands are expected exceeding the capacity of an individual cylinder with its supply
- when installing larger systems ensure a risk assessment is carried out in accordance
with approved code of practise L8 from the HSE
- ensure each cylinder is accessible for maintenance and replacement work as required
- ensure the hydraulic circuit from the solar loop is balanced, i.e. the correct flow rate is
achieved through each coil
