Air to water heat pumps Manufacturers online

Air-to-water heat pumps are environmentally friendly heating systems that extract thermal energy from the outside air and use it to heat living spaces or water.

They are a form of renewable energy and can be used for both heating and cooling.

Below you will find how air-to-water heat pumps work, an overview of different types, their areas of application and their advantages:

How air-to-water heat pumps work:

The way an air-to-water heat pump works is based on the principle of thermodynamic conversion.

The heat pump extracts heat from the outside air, even at low temperatures. To do this, a fan draws in the outside air and passes it through a heat exchanger (evaporator), in which the still liquid refrigerant is heated. This causes the refrigerant heated by the outside air to evaporate. The now gaseous refrigerant is fed into the compressor.
The compressor compresses the gaseous refrigerant, which further increases its temperature.
The hot, compressed refrigerant is now passed through another heat exchanger (condenser) where it condenses into a liquid and transfers its heat to the medium in the heating system.
In the downstream expansion valve or expansion valve, the pressure of the refrigerant is reduced back to the initial pressure and the cycle starts again.

Types of air-to-water heat pumps:

• Split heat pumps: These consist of two separate units - an indoor and an outdoor unit. The outdoor unit contains the evaporator and the compressor, while the indoor unit transfers the heat to the heating system.
• Monobloc heat pumps: In these models, all components are integrated into a single outdoor unit. They are easier to install, but require a direct connection to the heating systems.

Use of air-to-water heat pumps:

1. Heating systems:
Mainly for heating living spaces, especially in new buildings or renovated buildings with good insulation.

2. Domestic hot water heating:
Used to heat domestic hot water, e.g. for showers or kitchens.

3. Cooling:
Many air-to-water heat pumps can also be used for passive cooling in summer.

4. Industry:
In certain industrial applications, they are used for process heating and cooling.

Advantages of air-to-water heat pumps:

• They use renewable energy sources and help reduce CO₂ emissions.
• They can supply more energy than they consume (high seasonal performance factors), which leads to lower heating costs.
• Monobloc heat pumps in particular require less space and are easier to install.
• They usually have low maintenance requirements compared to other heating systems.
• They can be used for both heating and cooling and are adaptable for different applications.

Air-to-water heat pumps are an efficient and environmentally friendly heating solution that enables significant energy cost savings and CO₂ reductions by using the outside air. Their versatility and adaptability make them a popular choice for modern heating systems in residential and commercial buildings.

Here you will find an overview of the most important criteria to look out for when buying air-to-water heat pumps:

When buying air-to-water heat pumps, there are several important factors that should be considered to ensure that the heat pump you choose meets your individual requirements and needs.

• Determine the required heat output for your premises to ensure that the heat pump can provide sufficient heat.
• Check whether the heat pump is able to adapt to different heating requirements (e.g. temperature changes).
• Pay attention to the SPF, which indicates the ratio of heat generated to energy consumed. A higher SPF means more efficient use of energy.
• Check the outside temperatures at which the heat pump can operate efficiently. Some models are specially designed for cold climates.
• Check what flow temperatures (water temperatures) the heat pump can reach to meet the requirements of your heating system.
• Check the energy efficiency rating (e.g. A++ to G) of the heat pump to ensure it meets current standards.
• Pay attention to the noise level of the outdoor unit. This is particularly important if the heat pump is installed close to living areas or neighbors.
• Some models offer quieter operating modes or sound insulation.
• Decide whether you prefer a split or monobloc heat pump. Monobloc models are often easier to install.
• Check the space required for installing the outdoor unit and the indoor unit, particularly with regard to clearances and accessibility.
• Find out about the maintenance requirements of the heat pump. Less maintenance saves time and money.
• Make sure that the manufacturer or supplier offers good customer service and an easily accessible repair and maintenance service.
• Many air-to-water heat pumps also offer cooling options. consider whether you need this function.
• Check if the heat pump is compatible with smart home systems for easy control and integration.
• Consider the initial cost of the heat pump and compare different models.
• Estimate the long-term operating costs and the potential savings from using the heat pump.
• Look for relevant certificates (e.g. CE certification) that guarantee the quality and safety of the heat pump.

Choosing the right air-to-water heat pump requires careful consideration of the above factors to ensure that the system is efficient, cost-effective and adaptable to your specific heating needs. A good comparison of different suppliers and models can help you make the best decision.
