PO WER H EAT P U M P
The XRGI® CHP produces the electricity to run the PMHTM heat pump highly
efficiently with combined heat and power. Combined operation eliminates
the systemic disadvantages of operating the heat pump alone and increases
overall efficiency with the full use of the waste heat generated from electricity
production for heating.
The XRGI® control system ensures the smooth interaction of the heat generators
in a heating system

High-performance engine from Toyota further developed for EC POWER
Space-saving installation in the boiler room thanks to modular design
Optimised configuration enables the highest efficiency tested on the market,
consistently high efficiency even in the partial load range and whisper-quiet
operation
The iQ 20S is the heart of the power heat pump and takes care of the fully
automatic operation of XRGI® and PMHTM

Monobloc Outdoor Unit with closed R32 refrigerant circuit
Space-saving outdoor installation, quiet operation, high efficiency
Operating unit PMHTM CU with user-friendly touch display and 		consumer-side control of heating and hot water system

H Y D R AU L I C S
The XRGI® CHP and PMHTM heat pump are connected in series, whereby thePMHTM raises the temperature of the main return flow from the customer'ssystem. The PMHTM heat pump operates with a low temperature increase andthus the highest possible efficiency. The XRGI® CHP unit efficiently ensures therequired flow temperature all year round.

Hydraulic schematic diagram: Safety-related and functionally necessary components (e.g. pressure maintenance,ventilation, etc.) must be designed and installed according
to the state of the art. Heating water quality according toVDI 2035. Sludge separators and magnetite filters must be
installed before XRGI® and PMHTM.

PLANNING, INSTALLATION, COMMISSIONING AND INSTRUCTION

Detailed planning information enables easy and problem-free installation.
Commissioning is carried out by an EC POWER or EC POWER-certified service
technician. After commissioning, a briefing is given to the operators of thePHPTM power heat pump.

REGULAR OPERATION - BASE LOAD
Annual duration lineHeat output in %The XRGI® CHP unit and the PMHTM heat pump run in parallel.
The heat pump receives the start-up release when the start-up
phase of the XRGI® CHP is completed. If heat consumption drops,surplus heat generated is stored in the XRGI® Storage Tank and
PMHTM Buffer Tank. Once the tanks are full, XRGI® and PMHTM areswitched off.

Heat output in %The PMHTM heat pump is given the start release when the XRGI®
CHP can no longer ensure the heat supply on its own. If heatconsumption drops, surplus heat generated is stored in theXRGI® Storage Tank and PMHTM Buffer Tank. Once the tanks arefull, XRGI® and PMHTM are switched off.

SURPLUS MODE
If there is a surplus of renewably generated electricity, the operation of the XRGI® CHP is stopped. The heat pump (and possibly an additional boiler or electric heater) then provides theheat supply alone. The XRGI® control receives a signal via the VPP
gateway (potential-free contact) or the Modbus gateway (Modbus RTU protocol).
Operation when there is a surplus in the public electricity grid:
The electricity grid operator, a flexibility marketer or a trading
department provides the signal via the smart meter gateway.
OFFOperation in case of surplus in the property/quarter(customer installation):
The energy management system of the property/quarter supply,
which for example initially stores the surplus renewable energy
generation in a battery system, provides a signal when the battery
storage is fully charged.
