6 Description of the Pumps
n an average household, around 10 to 20% of the energy consumption is caused by common
standard pumps. With the Delta HE series of pumps, we have developed a circulation pump
with an energy efficiency index of
≤
0.20. The Delta HE pump can reduce energy consumption
by up to 80% compared to a standard circulation pump, whilst maintaining the same level of hy-
draulic power.
The pump output can be adjusted to the actual needs of the system, as it works according to
the proportional pressure process and has a switchable night setback.
