Ecoforest
Our history
The history of Ecoforest begins in 1959 thanks to the vision and determination
of Jose Carlos Alonso, who would become its founder and today its president. A
trip to the United States made him discover pellets, a fuel that at that time
was unknown in Europe. As a result, Ecoforest soon became the first
distributor of pellet stoves in Europe, laying the foundations for a market
that is now fully consolidated.
Some years later, in the 1990s, we went a step further and became the first
European manufacturer of pellet stoves, as well as the inventors of the pellet
hydro-stove, which allowed us to position ourselves internationally as a
reference in the HVAC and renewable energy sector.
After more than 7 years of research and experimentation in collaboration with
the University of Vigo, in 2012 we presented a new range of products, our
ecoGEO heat pumps, making us the first spanish manufacturer of ground source
heat pumps and the first european manufacturer to incorporate modulating
compressors (Inverter Technology) and 4-way valves for the production not only
of heating or DHW, but also cooling, representing a turning point in the
sector.
Always focusing on technological differentiation, in 2013, we developed our
air source with water-to-water heat pumps, an exclusive type of air source, in
which we introduced innovative technologies like defrosting without compressor
consumption or the possibility of the combination of collection
sources, for example, air and ground, getting the best of both, optimizing the
performance and cost of the installations.
This was followed by our range of high power heat pumps in 2014 and our peak
performance range tracking technology to optimise cascade operation in 2015.
Ecoforest offers all types of HVAC solutions using renewable energies, and is
the only spanish manufacturer of ground source heat pumps and leader in sales
in Spain.

Why paying for
something that is free?
Without realising it, we all come across forms of green energy everyday, more
in fact than our society will ever need. Most people now know about the
benefits of solar pannels and wind turbines, but few realise we have the
technology to take advantage of earth we walk on, or the air we breathe.
A huge part of the energy we use in our homes now goes towards heating and
cooling. Heat pumps are able to utilise the energy that lays dormant all
around us to power our heating, DHW and even cooling. All this is done at no
extra cost to the planet, making it an invaluable technology for our society.

¿How does an ecoGEO+ heat pump work?
COMPRESSION EVAPORATION CONDENSATION
EXPANSION
The system is based on the refrigeration cycle. It supports heat transmission
from one source (which can be air, water or soil) to another. But, why is this
system so efficient?
Heat pumps have the ability to absorb energy from external and free sources
(ground, water and air), which enables heat pumps to deliver more heating
power than the power they need to operate.
The performance factor is obtained by dividing the thermal power delivered to
the building by the electrical power consumed by the heat pump. This factor is
named COP, when the heat pumps operates in heating mode, and EER, when it
opetated in cooling mode.

Inverter technology : the modulating heat pump
Inverter technology, in contrast to conventional on/off technology, consists
of controlling the speed of the compressor in order to vary the thermal power
produced and the electrical power absorbed by the heat pump. The principal
reason for using Inverter technology for compressor speed management is that
it permits the operation of the heat pump to be adapted to the thermal demand
of the building at any given moment, optimising its performance and reducing
the seasonal electrical consumption of the unit.
When adapting the speed of the compressor, the power difference between the
demand of the building and the power of the heat pump is reduced as the pump
is able to provide the exact power at any given moment, also allowing for more
flexible installations
able to adapt correctly to each installation and save some of the elements of
the installation that would be necessary in the case of using an ON/OFF heat
pump. This means that heat pumps with Inverter technology are not only more
efficient, but also allow for more compact and economical installations.
Ecoforest has extensive experience in this technology, as it has developed all
its products using it from the very first model, being the only manufacturer
with a complete range of Inverter products.

The Ecoforest heat pump is the best option compared to the main types of conventional heating systems. The most important difference is the origin of the primary energy used by the heat pump, as it gets a large part of its energy from a renewable source that is not taken into account as consumption when calculating efficiency. For this reason, the efficiencies achieved by a heat pump are unattainable for other systems.

Product Range
Air source
Air source heat pumps use the energy of the air. Ecoforest has developed two
types of air source heat pumps: The ecoAIR+ monobloc heat pump, an innovative
product on the monobloc air source heat pump market that guarantees unique
performance even in the most unfavourable conditions and adapts to the needs
of the installation at all times. Another type of air source is the ecoGEO+ &
AU, a unique solution that combines an ecoGEO+ heat pump with an outdoor air
source unit (AU), providing extraordinary efficiency and even allowing for
hybrid ground source – air source systems to achieve a perfect balance between
investment and performance, a unique solution on the market.
Ground source
Ground source heat pumps make use of the energy contained in the ground. The
temperature of the underground is stable all year round, which makes it
possible to obtain very high performance all year round, independent of
external weather conditions. ecoGEO+ heat pumps are Ecoforest’s Ground source
heat pumps. These heat pumps have a very different technology, thanks to their
inverter technology and control strategies that make it possible to achieve
the most efficient and compact installations on the market. This range
includes products for domestic applications, such as ecoGEO+ Basic and ecoGEO+
Compact, as well as for commercial and industrial applications, ecoGEO+ HP,
making it the most complete and advanced range of Ground source heat pumps on
the market.

Ecoforest heat pumps
Photovoltaic combination
The ecoGEO+ and ecoAIR+ heat pumps incorporate hybrid management with
electricity production systems from renewable sources, which reduces
electricity consumed while optimising the operation of the heat pump in a
unique way. This exclusive management allows Ecoforest heat pumps to store, in
the form of thermal energy, excess electricity from renewable sources,
guaranteeing optimal consumption and minimising electricity consumption from
the network. This patented technology makes it possible to exploit the full
potential of renewable energies. It is a unique system that also makes it
possible to reduce the number of electric batteries required in a conventional
photovoltaic or wind power installation, or even eliminate them completely.
Accessories
A heat pump needs to guarantee comfortable conditions, which is why all the
details must be taken into account when installing the heat pump. The correct
choice of the elements that will form the environment of the heat pump is as
important as having an efficient heat pump. Ecoforest provides its customers
with the latest accessories for heat pumps, fully adapted to our products, in
order to obtain the most efficient installations. The Ecoforest range of
accessories is specifically designed for use with ecoGEO+ and ecoAIR+ heat
pumps. All the accessories offered by Ecoforest have been tested to determine
the best solutions for the installations.

Air source
How does air source work?
Air source heat pumps use the outside air as an energy source, producing
domestic hot water, heating and cooling. Using the thermodynamic cycle, they
use the energy in the air to produce the thermal energy required by the
building.
Air source heat pumps are more economical than Ground source heat pumps, but
their efficiency is influenced by external environmental conditions and their
annual efficiency is slightly lower than that of Ground source heat pumps.
Installation is simpler than ground source, requiring only the installation of
an outdoor unit that collects energy from the air and an indoor unit.
Air source is a solution with a lower initial investment than Ground source
and a performance slightly lower, but still much higher than that of
traditional heating systems.
Types of air source heat pumps
Air-to-Air Heat Pump
Air-to-air heat pumps exchange heat with the outside air and deliver this heat
to the installation by means of hot or cold air, the best known type of air
source heat pump is the commonly known air-conditioning.
Air-to-Water Heat Pump
Air-to-water heat pumps exchange heat with the outside air and emit this heat
to the installation through hot or cold water. This type of air source allows
us to heat radiators, underfloor heating or fan coils, in addition to heating
DHW.
Ecoforest air-to-water heat pumps are monobloc heat pumps. The monobloc concept means that all components of the heat pump are located in the outdoor unit and the connection between the outdoor unit and the building is fully hydraulic and not a refrigerant connection as in other cases.

Propane, the innovation is natural
The use of R290 is already present in a significant number of refrigerators. The reasons why this gas can be so interesting as a refrigerant are the following:
developed by Ecoforest makes the replacement of an old boiler very simple and economical, while guaranteeing the best comfort.
1. Natural gas not produced synthetically.
2. Almost zero greenhouse effect (GWP: 3).
3. Very economical.
4. Unique performance and efficiency.
5. Excellent working temperatures.
When changing a boiler to a heat pump, the key factor for the correct operation of the installation is the high temperature required by the radiators. The ecoAIR+ PRO heat pump allows you to reach more than 70°C without additional electrical support, even at the most extreme temperatures. The technology

ecoGEO+ & AU, a different type of air source energy
The combination of ecoGEO+ heat pumps with hidraulic air source units (AU) is
a unique solution with many advantages over conventional Air source heat
pumps.
The main components are situated in the indoor module and are not exposed to
the weather, which guarantees a long service life. The refrigerant charge,
which is also limited to the indoor unit, is much lower than in traditional
Air source units. In addition, there is no distance limitation between the
outdoor unit and the heat pump, which is indoors, as in other types of
systems. The noise level of the outdoor unit is considerably lower than that
of conventional Air source heat pumps, as the unit has no compressor inside.
A unique defrosting system, totally hydraulic and with the compressor stopped,
reduces the duration of defrosting cycles and their frequency, all without
activating auxiliary electrical elements, and allows to achieve high
performances. anuales excepcionales. In addition, for domestic applications,
the combination of ecoGEO+ Basic and ecoGEO+ Compact with air source outdoor
units (AU) makes it possible to take advantage of HTR technology. This
characteristic makes the system a more efficient solution, as the energy used
for defrosting is produced free of charge during heating production, which
also significantly increases the efficiency of the system.
These advantages make this system an ideal solution in Air source, with a
number of advantages over traditional Air source systems.

ecoAIR+
All-in-one, HK-Compact
This configuration, which combines an ecoAIR+ with the HK-Compact indoor
module, it’s perfect for compact and economical installations. The HK-Compact
indoor unit integrates all the main elements of the hydraulic system,
including a 165-litre stainless steel hot water tank. The ecoAIR+ heat pump
can manage up to 3 shunt groups with different temperatures. This scheme is
suitable for managing two zones (e.g. an underfloor heating and cooling
circuit and a radiator circuit) which can be connected without the need for a
buffer tank thanks to the wide modulation ranges of the ecoAIR+ units.
Maximum versatility, HK
This configuration, which combines an ecoAIR+ with the HK indoor module,
allows the installation to be adapted to every need, providing all the
services required: DHW, heating, cooling and swimming pool. The HK indoor unit
integrates most of the elements of the hydraulic installation, and it is
sufficient to fit the specific components required for each case. The image
below shows a DHW tank for high domestic hot water consumption and direct
heating/cooling production, with the circulation pumps, filters and valves
integrated in the HK unit.

Air source
ecoGEO+ & AU
Water-to-water heat pumps with air source
The ecoGEO+ Basic and Compact units (Models 2 and 4) can use air source
collection systems using the AU outdoor units, making possible Air source
installations where the heat pump is indoors and the outdoor unit is a simple
water exchanger. The installation shown in this example combines an ecoGEO+
Compact heat pump with an AU12, guaranteeing the production of DHW (165l
stainless steel tank integrated in the unit), heating/cooling in several
outputs (without the need for a buffer tank thanks to the wide modulation
ranges) and swimming pool, all controlled by the heat pump.
Hybrid collection system: Ground and air source
The ecoGEO+ units can also manage a hybrid system of ground source and air
source collection, a unique Ecoforest technology that allows optimal use of
both sources at any time. This has several advantages: on the one hand, the
number/ length of Ground source probes required will be significantly reduced
compared to a fully Ground source system, resulting in a more economical
system. On the other hand, the efficiency of the system can be higher than
that of a 100% Ground source system because the management will allow each
source to be exploited according to its efficiency at any given time.
Individual heat pump and common collection system, ideal for multiple
dwellings
This configuration is perfect for the implementation of energy transition
measures in buildings. It consists of a single Air source collection for the
whole building, usually installed on the roof or in an available area, which
can consist of a single unit covering all needs or several units distributed
according to the available space. Each flat has its own heat pump, an ecoGEO+
Compact for example, which requires only 1m2 of floor space, and can make
individual use of the HVAC in each flat. In addition, the energy meter is also
simplified. This type of installation offers higher performance than
conventional HVAC systems, without the classic heat loss of distribution
columns, and absolute individual comfort. It is also a very economical system,
as all units share the collector.

Ground source
How does ground source energy work?
The ground source heat pump extracts energy from the ground or water for
heating, cooling and domestic hot water production. The ground source heat
pump uses the thermodynamic cycle to provide these different services, for
heating it extracts heat from the ground or water and introduces this heat
into the building, and for cooling it extracts heat from the building and
transports it to the ground or water source.
Ground source heat pumps are also known as water-to-water heat pumps because
they extract heat from the ground or a water source through a water circuit
and transfer this energy to the building also
through a water circuit. Ground source systems have no visual or acoustic
impact. Ground source installations require a higher initial investment than
air source systems, due to the work associated with the collection circuit.
On the other hand, ground source heat pumps have better efficiency than air
source heat pumps. This allows for higher energy savings, making ground-source
heat pumps more cost-effective in the long run.
Types of collection systems
…
Vertical closed loop
These collectors consist of boreholes buried at depths generally between 80m
and 150m.
Horizontal closed loop
Horizontal heat exchangers are buried pipes in trenches
of 1-2 m deep.
Open loop
This system consists of an open circuit of water collected from the water
table. It allows the heat pump to extract energy after passing through an
exchanger.
Other
Ground source baskets, thermoactive piles,
round-source pillars…
Ecoforest ground source heat pumps ecoGEO+ can be paired to any type of collection system thanks to their control strategies that adapt their operation to the characteristics of each type of source.

HTR, heat recovery for the best performance
The HTR (High Temperature Recovery) system consists of a heat recovery unit that recovers the thermal energy discharged by the compressor at high temperature when the unit is producing heating or cooling.
achieving considerably higher efficiencies than conventional heat pumps, as the production of hot water is done “for free” by recovering the high temperature at the compressor discharge.
Through this heat recovery it is possible to produce domestic hot water up to 70ºC. This unique technology also allows the simultaneous production of DHW and heating or DHW and cooling,
This, together with their Inverter technology and Ecoforest control strategies, makes the ecoGEO+ Basic & Compact units the most efficient ground source heat pumps on the market.

Simultaneous cooling and heating, the solution for high demands
The thermal needs of industrial, commercial, agricultural, etc. buildings
present different energy demands than those corresponding to domestic demands.
Depending on the type of use and the services that the building has to
provide, these can vary enormously.
It is common that in certain types of buildings, such as hotels, sports halls,
spas, centres, agricultural facilities, etc., it is necessary to satisfy
heating and cooling needs simultaneously almost all year round. It is in this
type of application where a total heat recovery installation (simultaneous
production) becomes an ideal solution, and Ecoforest has therefore developed
an exclusive technology for the management of this type of installation.
The ecoGEO+ HP heat pumps can manage this type of installation. Thanks to
Ecoforest’s control strategies and their great modulation capacity, they can
modulate their power to adapt it to the most important thermal demand at any
given time and use their collection as a source of energy or as a dissipation
system in a modulated way to achieve the correct thermal balance in each
operating condition.
This makes this solution the simplest, most efficient and economical for this
type of installation in which greater efficiency means greater savings and the
guarantee of correct operation is critical.

ecoGEO+ Basic and Compact
Simplicity and versatility
ecoGEO+ Basic units can be installed with an external hot water tank, so the
size can be chosen according to the needs of each installation. The
circulation pumps, expansion valves, safety valves and the three-way DHW valve
are integrated in the unit, making the installation very simple and compact.
This diagram corresponds to an installation in which the required services are
domestic hot water and heating/cooling in a single circuit. As the heat pump
includes the circulation pumps inbuilt, it is not necessary to add a buffer
tank and no additional hydraulic elements are required.
The most compact all-in-one system
The ecoGEO+ Compact units incorporate a 165 litre stainless steel hot water
tank. This compact design allows the user to meet the needs of DHW, heating,
cooling and pool heating. A four-zone heating/ cooling installation, which
would be very complex with other heat pumps, is very simple and easy to
install, as it is possible to avoid installing a buffer tank thanks to the
high modulation capacity of the ecoGEO+ heat pumps. In addition, the heat pump
also manages the heating of the swimming pool.
The smart cascade
The ecoGEO+ Basic and ecoGEO+ Compact heat pumps can be installed in a cascade
of up to 3 units in parallel, reaching a total modulating capacity between 5
kW and 66 kW in a single installation. This does not require any additional
control devices, the cascade management is integrated in the control
strategies developed by Ecoforest. These control strategies for cascade
installations have a number of advantages, as the system accurately tracks the
operating hours of each unit in the cascade to prolong its lifetime, and
prioritises its operation at half load to optimise its performance at all
times. In addition, the management capacity is multiplied by the number of
units in the cascade, resulting in installations capable of meeting any
demand.

ecoGEO+ HP
The ideal solution for a classic installation
The ecoGEO+ HP heat pumps enable more efficient and simpler installations for
industrial applications. This is also applicable to residential buildings with
high thermal needs, as their ability to manage up to 5 heating/cooling zones,
the integrated cycle inversion and the possibility of installing a DHW tank
according to the needs of each building, make these units capable of adapting
to any type of demand. They also use Inverter technology, with modulation
ranges of up to 80%. This makes it possible to considerably reduce the volume
of buffer tanks required, or even eliminate them altogether.
Cascade and simultaneous production
The ecoGEO+ HP heat pumps can be installed in cascades of up to 6 units in
parallel, this management capacity is possible thanks to the use of the
ecoSMART Supervisor, which allows an equal distribution of the operating hours
of each unit in the cascade, optimising the life and efficiency of the system
by seeking partial load operation of all the heat pumps. In addition, these
heat pumps can manage heat recovery installations, simultaneous production of
heating and cooling, with unique performance thanks to the exclusive control
strategies developed by Ecoforest. These two features make the ecoGEO+ HP
ideal for installations where heating and cooling needs often occur
simultaneously and represent a significant thermal power. In addition, the
management capacity of the ecoGEO+ HP heat pumps is multiplied by the number
of units in the cascade, making this system more complete in terms of control
of the installation and its elements.

PV ready heat pumps
Unique combination with photovoltaic installation
The ecoGEO+ and ecoAIR+ heat pumps incorporate hybridization management with
electricity generation systems from renewable energy sources, which reduces
electricity consumption while optimising the operation of the heat pump in a
unique way.
This patented technology optimises the available resources in order to achieve
self-consumption. In the event of excess electricity production, the heat pump
is activated and modulates its power to consume only the excess electricity,
achieving a “zero” balance between production and consumption.
This PV ready combination with our heat pumps is compatible with all types of
installations and systems.
This is only possible thanks to Ecoforest’s advanced control strategies and
the performance and modulation capacity of the ecoGEO+ and ecoAIR+ heat pumps.

How does it work?
The heat pump is connected to an energy meter that provides a reading of the
electrical balance between the grid and the house.
In the event that the injection reading corresponds to sufficient electrical
power to start the system, the heat pump will activate a “surplus mode” by
which it will modify the setpoints of the main Services of the installation to
store thermal energy thanks to this free and renewable electrical energy that
would be injected into the grid if it were not consumed through this
functionality.
This excess power is variable and can change over time, which is why the high
modulation capacity of the ecoGEO+ and ecoAIR+ heat pumps is so important. The
heat pump will adapt its consumption to consume only the excess energy
available at any given time.
Once there is no more excess energy available, the heat pump will return to
its normal operating mode, and will have stored as much energy as possible in
the form of thermal energy for the different services. In this way, the
services can be supplied at a later date without the heat pump having to be
switched on, thus saving a large part of the electricity consumption from the
grid.

ecoSMART e-system, a compact solution for homes
The ecoSMART e-system is a unit designed for use in domestic installations to
obtain more compact and efficient systems.
This unit includes a photovoltaic inverter, the e-manager and a number of
electric batteries to be chosen according to needs, so that all the components
of the photovoltaic installation are already included and do not need to be
installed.
The e-system is compatible with single-phase domestic installations of less
than 5 kW of renewable electricity production and can be connected to up to
two lines of photovoltaic panels. It is compatible with all types of
photovoltaic panels.
The storage capacity is modular and selectable. The e-system can integrate
from 0 to 5 electric batteries of 2.4 kWh each, reaching a maximum storage
capacity of 12 kWh, which is more than enough for domestic applications and
consumption in individual homes.
These functionalities make it possible to reduce the energy bill by managing
the surplus of renewable energy, controlling the electricity tariff and
regulating the power consumed by the installation.
