Examples of typical applications
ecoGEO heat pumps are designed to provide comprehensive heating/cooling and produce DHW (domestic hot
water) all year round, using a simple installation and ensuring the maximum energy efficiency possible.
Maximum Energy Efficiency.
Because of its wide regulatory capacity, ecoGEO heat pumps suit the needs of thermal energy for DHW,
heating, or heating/cooling that exist at any time. The compressor with inverter technology and the highly
efficient variable speed brine and heating pumps provide optimal flow rate and outlet temperature at all times,
so that the heat pump always operates at peak efficiency. Moreover, the inverter control of the heat pump can
minimize ecoGEO equipment start/stop cycles, which results in increased energy efficiency.
Simple, economical installation
Capacity and outlet temperature regulation provided by ecoGEO heat pumps considerably simplify the
heating/cooling installation. First, in simple facilities may not be necessary to have a buffer tank, even in
installations with heating using fan-coils or low temperature radiators. Moreover, ecoGEO heat pumps can
provide two different outlet temperatures by simply adding external 3-way modulating valve and a circulating
pump, without using additional control systems.
This can simplify installation and reduce cost significantly.
General Installation Recommendations
Geothermal heat pumps in general, and ecoGEO heat pumps in particular, provide maximum performance
when used energy in heating installations fitted with low-temperature heat emitters. This means the ideal
application is underfloor heating, using a radiant floor surface, as these require low outlet temperatures
(around 35°C).
However, ecoGEO heat pumps allow outlet temperatures of up to 55°C, so they can be used in heating with
medium temperature emitters such as fancoils, convector heaters or low-temperature radiators. In this type of
installations ecoGEO heat pump also ensure maximum efficiency. However, it should be noted that the
increased outlet temperature of the heating system increases the energy consumption necessary for heating
the water and thus reduces the energy efficiency that can be obtained with the heat pump. Thus, an increase in
the outlet temperature from 35ºC to 50ºC means a reduction in energy efficiency of approximately 25%. To
mitigate this effect we recommend over-dimensioning the thermal emitters in the heating system to minimize
the required outlet temperature and/or increasing the thermal insulation of the building.
NOTE
The following examples of installations are only approximate and it may be necessary to install
additional components (valves, fasteners, etc..).
The installation must be designed by qualified personnel, in accordance with applicable local
regulations.
