Elementar Heat pumps
Elementar line succeeds in providing high rank of COP efficiency (ration of the produced thermal power to the consumed electrical power, which measures the efficacy of the pump in standard conditions of operation), whereas with the Inverter technology, which alters the pump performance adjusting its operation to the needs and demands of each space in heating / cooling, greater COP efficiency rank is succeeded along with substantial energy saving.
Elementar heating pump system consists of the outer unit unit (with Panasonic compressor) and the inner unit (with Wilo circulator, embedded expansion vessel of 10 liter capacity), while it is controlled from the electronic central controller of advanced technology, which is embedded in the inner unit.

What are heating pumps?
Which are the types of heating pumps?
Air to water pumps or air to air pumps, pumping the heat from the air of the environment.
Geothermic pumps, pumping the heat from underground.
How do heating pumps work?
What is the operating principle of the heating pump?
This is done with a small, compared to other heating systems, energy consumption.
The basis of its operation is the exploitation of the thermal properties of the refrigerant (freon) which it uses:
The heat pump performs a refrigeration cycle using the coolant, which depending on its physical state (liquid or gas) contains basic thermal properties.
The circulation of the refrigerant is carried out by the following parts of the heating pump:
- Compressor
- Condenser
- Expansion valve
- Evaporator or vaporizer
When operating the air-to-heat heating pump, the fan communicates with the outside air and pushes it inside the heating pump, where it meets the evaporator.
When operating the water-to-water pump on heating, a closed or open water circuit is circulating and meets the evaporator.
This, as part of the closed operating circuit of the refrigerant, meets the freon and converts it into a very low temperature gas. Thereafter, the gaseous medium enters the compressor, whereby high pressure reaches high temperature and then passes through the condenser yields that heat to the consumption.
Finally, the refrigerant through the condenser returns to its original liquid form and the cycle starts from the beginning.
How does the heating pump work during summer for cooling?
In this case, the internal circuit of the heating pump runs counterclockwise to provide cooling. This is done by means of a four-way alternating valve, which reverses the refrigerant cycle and the heat pump from heating mode “turns” to cooling mode. Thus, the freon, inversely moving, essentially absorbs heat from the heat exchanger of the consumption and delivers it to the heat exchanger of the source.
How is a heating pump installed?
- In any active residence.
- In dwellings under renovation or under construction.
- In dwellings that already have a gas or oil boiler (and you can use heating pumps either autonomously or in combination with the existing heating system).
- It is important to emphasize that there is no need for a special space to place the heating pump (no boiler room or fuel tank required) or extra work.
The unit can under specific conditions be placed even on a balcony.
How does the heating pump use energy sources?
In the case of an air-to-water heating pump, the source of absorption or energy efficiency is ambient air.
In the case of water-to-water heating pump, the source of absorption or energy efficiency is the closed or open circuit of water circulating or pumped to the ground and called a geothermal heat exchanger.
The closed-type geothermal exchangers are divided into horizontal & vertical.
Horizontal geo-exchangers: water solution with antifreeze fluid circulates in a closed circuit of pipelines, which are placed in a small depth in the ground.
Vertical geo-exchangers: Vertical drilling at deep depth is created, where a water solution with antifreeze fluid is circulated again in a closed pipeline circuit.
The open-ended geothermal exchangers are vertical and use drilling water sources in the ground. The water is pumped and after passing through the heating pump, it is reintroduced into a second well at a sufficient distance from the original.
Which terminal units can be used with heat pumps?
Underfloor heating and cooling systems.
Fan Coil Units for heating and cooling.
Boilers for hot water.
Swimming pool water heating (directly or through an external heat exchanger).
What is the efficiency of heating pumps?
The degree of efficiency in heating pumps can have a starting value of 2.5 to 3 for water-to-air pumps and up to 5 in the case of geothermal pumps.
The reason for this is because heating pumps do not directly convert electricity into thermal, but initially into a kinetic drive by moving the electric compressor.
In practice, the efficiency level means that an air-to-water heating pump 3 delivers 3 kilowatts of thermal energy per kilowatt-hour of electricity, making it more economical than other conventional systems.
What are the advantages of using heating pumps?
They are 100% autonomous systems (they do not need fossil fuels to work, since they use ambient air or subsoil as sources of energy).
They provide heating and hot water at the same time and at the same cost.
They can also get heating in winter and cooling in summer through the same installation.
They can be installed both in new buildings and in existing dwellings.
They are easy and quick to install (the outdoor unit is even installed on a balcony, saving space without requiring a boiler room or fuel tank).
The existing heating – cooling system (underfloor heating or fan coils) is maintained and it is possible to combine with the existing boiler room or with solar heating systems.
They have high energy efficiency.
They have noise-free operation.
They have minimal maintenance requirements.
They are extremely safe to use due to the absence of combustion and storage of some flammable material.
They are environmentally friendly, since they do not pollute the atmosphere with exhaust gases.
They have low energy footprint due to a reduction in carbon dioxide emissions, which raises the energy class of a home.
They have efficient operation at low and high ambient temperatures (from -20 ° C to 48 ° C).
It is the only method that can offer both cooling and hot water while cooling.
How economical is the use of heating pumps? Which are the consumption savings?
Given the fact that through a change of heating pump boiler we can make small but beneficial changes to the installation (correct adjustment of the instrument components, better pipe insulation, etc.), the energy saving rate can be further improved.
