Hydro tower / combination tank
Hydro tower with external heat pump manager
Compact installation for heating and domestic hot water preparation
HWK 332
The hydro tower enables the fast and simple connection of a heat pump for heating purposes to a heating system with an unmixed
heating circuit.The heat pump manager included in the scope of supply of the heat pump is used for the electronic control of the com-
ponents (external wiring required). The following components are installed in a space-saving way and wired ready for use:
• Switchable pipe heater (2/4/6 kW)
• Buffer tank (100 l) with installation option for an additional immersion heater (up to CTHK 634).
• Hot water cylinder (300 l) with installation option for an additional heating element (flange heater).
• Electronically regulated circulating pump (energy-efficiency class A) pre-wired with coupling relay for an unmixed heating circuit
(consumer circuit).
• Unregulated circulating pump integrated for the generator circuit and hot water circulating pump.
• The hydraulic isolation of the generator circuit and the consumer circuit is done via two differential pressureless manifolds (bypass
pipes), which are each fitted with a check valve.
The unregulated circulating pump in the generator circuit is only operated when the compressor is running in order to reduce the
runtimes.The uniform flow through the buffer tank connected in series extends the runtimes of the compressor and ensures the required
heating water flow in all operating situations.
