The hydro tower with integrated
WPM EconPlus regulation ena-
bles the fast and simple connec-
tion of a high-efficiency air-to-
water heat pump installed out-
doors to a heating system with
an unmixed heating circuit. The
following components are in-
stalled in a space-saving way
and wired ready for use:
a 100l buffer tank, a 300l do-
mestic hot water cylinder, a cir-
culating pump for the generator
circuit (M16), an electronically
regulated circulating pump for
the consumer circuit (M13), a
domestic hot water circulating
pump (M18) and switchable
supplementary heating (2, 4,
6kW).

carried out using a dual differen-
tial pressureless manifold
(Chapt. 8.3.5 on page 97).
