How does the Greenstar Plus Hybrid System work?
The Greenstar Plus Hybrid System aims to reduce running
costs and increase CO
2
savings. Once the fuel tariffs have
been inputted into the control unit, the Greenstar Plus
Hybrid System calculates and controls the optimal fuel
efficiency between the Worcester gas-fired boiler and the
electric air to water heat pump.
Greenstar Plus Hybrid Manager
The intelligent Greenstar Plus Hybrid
Manager combines the Worcester EMS
gas-fired condensing boiler and external heat
pump. This innovative software within the
Hybrid Manager automatically ensures, at
all times, the most efficient operation mode
between both energy sources depending on the chosen
strategy from the FW200 weather compensation controller.
The FW200 strategy consists of the following:
•
Strategy 1: Cost optimised
•
Strategy 2: CO
2
optimised
•
Strategy 3: Changeover temperature
•
Strategy 4: CO
2
: cost mix.
Greenstar Plus Hybrid External
heat pump
The external heat pump collects and
transfers the available heat from the
outside air to inside the property. As
well as being fuelled by the free and inexhaustible supply
of latent energy, the external heat pump offers a number
of advantages, such as ease of installation and siting, while
being suitable for a wide variety of property types and
sizes. At a time when fuel costs are rising, the external heat
pump gives the homeowner the opportunity to help reduce
their heating bills. For more information on whether this
system is suitable for your property, see page 12.
Please note: The heat pump must be installed by a
qualified refrigerant engineer.
