Elementar Heat pumps 

Apollo Teck GmbH offers a top product in air-water heating pumps, for the coverage of heating, cooling and hot water needs in household applications. Elementar line comes with international certifications (CE, TUV, GS, UL, SASO, OHSAS, ISO 9001, ISO 14001, EUROVENT), as well as environmental protection certifications (IECQ, ROHS etc.).

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?
Heating pumps are an alternative method of heating, which is indeed the most economical in comparison to all the other heating systems. They are based on the function of a device, which “pumps” heat from the air or underground and spreads it to the space requiring heat.
Which are the types of heating pumps?
There are two 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?
Heating pumps work on electric power.
What is the operating principle of the heating pump?
The heating pump is a device that essentially transfers heat from a place called “source” (air, soil, water) to a second part called “consumption” (underfloor heating, fan coil units, radiators etc.).

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?
The heating pump can also be operated in summer for cooling (with Fan Coil) or cooling (with underfloor system).

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?
Heating pumps are easily and quickly 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?
A source is the energy space from which the heating pump absorbs or delivers energy, depending on its function.

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?
(Panel, AKAN, etc.) for heating.

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 a heating pump (COP for heating and EER for cooling) is called ratio of the heat output to the electric power consumed.

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 provide greater economy than all other heating systems due to a higher efficiency factor (saving 60-74% compared to heating oil and 50-60% compared to natural gas, depending on the system used, for instance pump air-water, air-to-air or geothermal pump).

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?
Continuous increases in oil prices have led to the solution of heating pumps, as they are the most economical heating medium.

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.
