The design icon of heat pumps

Die AEROTOP® SG is a RedDot Winner 2022 and has been awarded the iF Design Award 2022.

 
  • Two heat pumps from the 2000s are standing in a garden and being compared with each other

    The need for change

    There is a difference between just placing a heat pump outside and designing it specifically for that purpose.

    In the early 2000s, outdoor air-water heat pumps started to become a more popular alternative to indoor solutions. The reasons for this success were the increasing efficiency, easiness of installation and space saving in the house.

    The disadvantages were the noise produced by the significant amount of air moved around the evaporator and the aethetically simple design. The tall boxes – sometimes even with silencers attached, to reduce the noise – were very intrusive and nearly impossible to fit into the architecture and landscape surrounding them.

    So the requirements we gave our R&D team were clear – Instead of just adapting an indoor air water heat pump to an outdoor positioning, we needed a heat pump designed specifically for outdoor use: Extremely silent and efficient but still compact and able to blend into its environment.

  • A man working at a computer, looking at a 3D model and technical drawings of a heat pump on the screen

    A brilliant Idea

    Our R&D team knew, that in order to reduce noise they had to use a much larger evaporator – the part of the heat pump that extracts the energy from the air passing through the fins.

    To fulfill the compact dimension requirement, instead of the flat evaporator that heat pumps usually use, the idea was to design the evaporator in a circular shape.

    The result was an unusual looking heat pump, with a small footprint and less height. It was definitely a technological breakthrough, but we were missing a convincing design.

    The creation of a design icon

    After an online market research with home owners on different design options, the industrial design office Weinberg & Ruf started working on their first proposals.

    With their team of designers, constructors and graphic artists – and after many different iterations – they were able to create the timeless, unique and non intrusive design that conveys value and advanced technology.

    Complementing your Architecture

    The compact and non-intrusive design, as well as its stainless steel casing make the AEROTOP® SG blend seamlessly into its environment.

    What makes a design icon? We think it’s the result of a smart idea that solves a real problem with no trade off.

    The unit had to meet all three core requirements in equal measure – minimum noise emissions, maximum efficiency and an unobtrusive design.

    In terms of functionality, the AEROTOP® SG impresses with exactly these properties – without compromise.

    The design follows exactly this approach and thus carries to the outside what the device is about on the inside.

    And that, for us, is what makes a design icon: timeless, performing and high-quality – a perfect complement for the highest architectural standards.

Installation

 

For floor installation, the heat pump requires a stable base and is usually installed on a surface foundation. In areas with heavy snowfall, it is recommended to adjust the base height accordingly.

An example of how the installation can look is shown here:

 
 

During operation of an air-to-water heat pump, the evaporator on the air intake side can freeze up, depending on the weather conditions. This layer of ice must be defrosted regularly and the resulting condensation, up to 50 litres per day, must be drained. There are various options for draining condensation:

 

  1. Free draining into a gravel bed. The gravel layer must extend into the frost-free area in the floor under the heat pump.
  2. Drainage into a layer of gravel below the ground in the frost-free area.
  3. Drainage into the sewerage system. A siphon must be used here.
  4. Discharge into the building and from there into the sewerage system. A siphon is also mandatory here. The use of lifting systems is not permitted.

    with an integrated room temperature sensor for one or two heating circuits. The unit features an attractive design and built-in display lighting, allowing for easy operation by the user. From the living space, the operating mode and temperature settings can be adjusted, and all essential heating information can be read. This ensures optimal comfort with maximum energy savings.

  • Close-up view of the trunk line

    Trunk line

    The pre-assembled trunk cables enable clean and quick installation. Advantages of pre-assembled trunk lines:

    • Different lengths and pipe sizes: The trunk lines are available in 5 different lengths, in both DN32 and DN40 pipework. They are made of insulated corrugated stainless steel pipe, which ensures high flexibility and durability.
    • Protected hydraulic and electrical lines: The hydraulic and electrical lines are housed in a protected casing pipe, which protects them from external influences such as weather or damage and ensures a safe installation.
    • Airtight and watertight design: The long-distance lines are airtight and watertight, which ensures reliable operation and a long service life.
    • Tight against pressurised water: Thanks to the masonry sealing set of the casing pipe for the wall penetration, the long-distance pipes are tightly sealed against pressurised water, which prevents the ingress of moisture and additionally secures the installation.

There are many similarities between a heat pump system and one with an alternative heat generator, such as an oil, gas, or pellet boiler. The main difference is that a heat pump is installed outside the property, while a boiler is traditionally installed inside a property. The diagrams below show two simplified systems, which both provide heating and domestic hot water.

Return buffer

Diagram of the wiring schematic for a return buffer

If the volume of water in a heating system is relatively small, a buffer tank helps to balance the system and ensure the heat pump works efficiently. The buffer tank also facilitates the heat pump's defrost cycle without taking heat from the system's heat emitters.

Combi buffer tank

The buffer in this system is supplying heat to the heating circuit, as well as a fresh water station. Plus, in summer, solar PV panels can provide energy to the buffer, which can be used for domestic hot water.
