Developed to be quiet
The AEROTOP® SX7 achieves a sound power level of 47 dB(A) and a sound pressure of 42 dB(A) in reduced night mode and at a distance of 1m (when mounted directly on your house wall). At a distance of 3m, the sound pressure is only 33 dB(A). Noise protection guidelines are fully adhered to, allowing for installation in residential areas while making units ideal for smaller properties.
There are many considerations to make regarding noise when positioning an external heat pump. These include ensuring units are sited at a sufficient distance from neighbouring buildings - especially areas requiring sound protection, such as bedrooms. The type of residential area is also important, as different noise limits apply to specific locations. Any airborne sound can be reduced by structural measures, but not by planting, while structure-borne sound can be minimised through isolating the unit from the building. We recommend using flexible connecting hoses to decouple vibrations, as well as observing the minimum distances to the unit to reduce sound reflection (and eliminate the risk of blocking of air currents). Finally, you should avoid reflective surfaces, as every reflective plane doubles the sound pressure level!

Well thought out in detail
The AEROTOP® SX benefits from state-of-the-art technology, providing you with unrivalled levels of quietness, efficiency, reliability and safety. Its electrical, hydraulic and condensate connections are all straightforward, while aiding quick and flexible installation.
Intake grille
A specially designed intake grille splits the air flow before it enters the fan. This reduces air turbulence caused by uneven flow through the evaporator and prevents turbulent air from hitting the rotating impeller blades of the fan and causing noise. The result is lower sound power and a more comfortable environment.
Air ducting
A flow-optimised fan embedded in a specially designed housing creates a high-efficiency airflow, resulting in lower fan speed and the lowest possible flow noise. The flow is further enhanced by a hemispherical grille on the intake side of the fan inside the heat pump. The concept is rounded off by fins on the discharge side.
Efficiency
The AEROTOP® SX boasts excellent efficiency values, thereby ensuring lower operating costs. In both the high-temperature and low-temperature ranges, the unit achieves the premium efficiency class A+++ (1).
Always full power. Lower efficiency.
A non-modulating heat pump will have only two operational modes: Full power or off. This means that when operational, it will permanently deliver the highest possible output, even if this is not needed due to higher outside temperatures.
Modulated power. No efficiency loss.
The AEROTOP® SX, on the other hand, can modulate its output. This means it reacts to your heating demand in accordance with the ambient temperature, delivering the exact energy required. This saves your running costs and makes the heat pump significantly more efficient.

What is SCOP?
SCOP stands for the Seasonal Coefficient Of Performance of the unit. The value shows how much heat energy is generated per 1 kWh power supply on an annual average. The above data is given in accordance with EU Regulation No. 813/2013 at average climate conditions for low-temperature applications (W35). The figures shown are a maximum heating output at a flow temperature of 35°C and an outside temperature of -7°C.
New construction and renovation
The AEROTOP® SX should always be your first choice, as this standalone heat pump can warm your home even when the weather is very cold outside.
New construction
The lower the temperature difference between the outside air (heat source) and the heating temperature (heat sink), the more efficiently a heat pump operates. In new properties, low-temperature underfloor or wall heating systems are predominantly used, as they can run from heat pumps - even at very low outdoor temperatures.
Renovation
Many existing homes already have radiators or panel heating systems. A heat pump can also supply these systems without any problems. However, the aim should be to keep system temperatures as low as possible. So, if the conversion to a panel heating system is not planned, it can make sense (in some cases) to replace the existing radiators with larger models, allowing for the same output to be delivered into the rooms as before but with a lower system temperature. Your local installer will be happy to answer any questions about whether the replacement is necessary.
During extreme cold
The AEROTOP® SX delivers flow temperatures of up to 60°C when ambient temperatures are as low as -10°C. The unit can even operate when the outside temperatures are as low as -20°C. Temperatures below -10°C, or even -20°C are infrequent and only last for short periods in Central and Southern Europe. However, if the heat output of the heat pump is no longer sufficient during cold spells, the AEROTOP® SX has an integrated back-up heater to provide additional support.
Cooling
Did you know a heat pump can also cool? Although the AEROTOP® SX is a heating heat pump, by reversing the cooling cycle, it can also cool. In cooling mode, the heat pump extracts energy (heat) from the building and dissipates it into the environment via the evaporator and fan. This causes the room temperature to drop, using the same principle as a refrigerator. Please note: Cooling is not possible via conventional radiators.
Cooling via fan coil units
Fan coil units, operated in a separate circuit, can provide significant cooling. Installing the cooling circuit and fan coil units separately allows for flow temperatures as low as 7°C. This is the most common system used for cooling.
Cooling via surface heating systems
Cooling can also be achieved via floor or wall heating systems. However, the cooling effect here is considerably lower than that achieved with convectors because, among other things, condensation must be avoided. As a result, the flow temperatures are approximately 18°C and room temperature can be decreased by approximately 3°C.
Sustainability
With decades of experience in designing and manufacturing heat pump technology, ELCO has a wealth of knowledge and expertise developing sustainable heating solutions.
PV integration
Solar photovoltaic (PV) systems convert energy from the sun into electricity, which can then be used to power your AEROTOP® SX heat pump. The use of PV batteries and dedicated PV functions in the heat pump support the use of free, renewable energies.
Sustainable
Our AEROTOP® SX heat pumps use R32 refrigerant, which has a low global warming potential (GWP) compared to R410A.
Low operating costs
The AEROTOP® SX achieves high COP and SCOP values. The best possible efficiency is the key to low energy consumption - and exceptional sustainability. Our unit and system designs use the best possible parts and components to maximise efficiency and performance.
The R32 refrigerant with low GWP
All our AEROTOP® SX heat pumps use R32, a safe and efficient refrigerant with a much lower GWP (only 1/3) compared to R410A.

PV integration
The AEROTOP® SX can be powered by solar PV (photovoltaic) electricity. Using this green electricity makes heat pumps even more sustainable. As a result, combining a heat pump with a properly designed PV system is ideal in terms of both sustainability and energy cost reduction.
