The air -to -water heat pump is already the most popular heating system type in new buildings. Learn more about their working principles, advantages, and disadvantages, as well as matters that should be considered in new buildings or existing buildings.
The benefits of air source heat pump
If you choose this type of heat pump, you will benefit from many advantages.
1) Environmental protection
The air source heat pump only requires electricity to generate heat without any fuel, such as natural gas, oil or wood. This means that the heat pump heating system does not emit any carbon dioxide or particulate matter at all, and is particularly friendly to the climate.
Of course, the power generation of the gas and coal -fired power stations will indeed generate carbon dioxide. However, over time, more and more renewable energy is added to the energy mixture used in Germany. In this way, the heat pump will automatically become more neutral. If you use green electricity, they can even achieve 100% climate neutrality now. read more
2) Facing the future
If you use the Air to Water heat pump to hear your house, you can be independent of the transportation of oil or natural gas and the rise in future fuel prices. If you use these environmentally friendly heating systems, you don't need to worry about future ban and restrictions. read more
1) Low maintenance
The function of the heat pump is based on a long -tested reliable technology. Due to this and other reasons, the maintenance cost is lower. For example, it is not necessary to regularly and complex cleaning like many boilers. read more
2) High efficiency
The air source heat pump can generate four kWh or more calories from one kilowatt -kilowatt -hour power. Compared with other types of heating, the heat pump heating system uses input energy very effectively.
1) Low procurement cost
The air -to -water pump is cheaper than the water heat pump or water -to -water pump.
2) Cooling and heating
The air source heat pump can not only produce comfortable warmth in the cold season. If you have a floor heating system, they can also provide a mild cooling in summer.
The disadvantage of air source heat pump
The modern heating system using air to water thermal pump is indeed very effective. However, salt water and water -made water -made water pumps are more efficient, so they consume less power. In addition, the energy output of the Air to Water heat pump when the outdoor temperature is low is not as good as the higher temperature.
The other two points you should understand: air to water heat pumps may be cheaper than other types of heat pumps, but they are still more expensive than fuel or gas boilers.
The air source heat pump requires a lot of air. Consider the installation location during the planning phase and the noise generated when the fan inhale the air. It is best to choose an ultra -mute model.
Types of air source heat pump
If you use this type of heating system, you can choose from various designs to adapt to the specific situation of the building.
Monoblock heat pump for outdoor installation
The Monoblock heat pump combines all components in a shell. This makes the installation easier. When it is installed outdoors, the air -to -water heat pump will be located in the garden or courtyard of your home. This saves the space of the boiler room.
Monoblock heat pump used for indoor installation
If it is installed indoors, install a Monoblock air source heat pump in the boiler room. In this case, the pipeline for heat transfer is particularly short.
Split heat pump
For split heat pumps, technical components are divided into outdoor and indoor machines. This design is particularly flexible. When the refrigerant circuit leads to the inside of the building from the outside of the building, it must be installed by a specially trained refrigeration engineer.
DHW heat pump
DHW heat pump is a special type of air source heat pump. They only provide hot water for the bathroom and kitchen, and do not provide calories for running heating systems. DHW heat pump is usually equipped with a water tank. They are very suitable for installation during the renovation project, because they can become an ideal supplement to the traditional type heating system.
Precautions for selecting air source heat pumps
When the air source heat pump and the radiation board heating (such as floor heating) are used in combination, it can give full play to its potential efficiency. The lower the flow temperature, the better their work. Therefore, when planning heating, it is very important to consider the entire heating technology system. If you want to use the heat pump to cool down later, you should consider this factor during the planning stage.
Whether your home is new or old, you should consider the following points to ensure the perfect operation of your heat pump system:
1. The higher the seasonal performance coefficient (SPF) of the heat pump, the higher the efficiency it uses the power to generate electricity.
2. Like a washing machine or a refrigerator, the heat pump must be labeled with energy efficiency label issued by the European Union.
Make sure your device has a +++ tags.
3. Modern air with INVERR technology to water thermal pumps can adjust its heating output.
This means that they only generate the current heat required by your home, thereby reducing the power consumed by the air source heat pump and reducing the cost of operation and heating.
4. Some refrigerant used in the heat pump is a powerful greenhouse gas. If it is leaked into the environmental air, its effect is much stronger than carbon dioxide.
Refrigerant R290 is a natural substitute for climate -friendly.
Answer your question about air to water heat pump
1. Is there a building suitable for the heat pump heating system?
Yes, in principle. But old houses may need more refurbishment and renovation measures than new buildings. If the airflow comes in from the old windows and the heat is absorbed through the unprepared wall, you should combine the installation of the air source heat pump with the energy -related transformation of the building fence structure. In this way, you can ensure that the heat pump works as efficient as possible.
2. Do I need air permits for water heat pumps?
Can't. The air source heat pump is a heating system. You can install it without obtaining a permit.
3. Should the air source heat pump heating system be equipped with a water tank?
The heat pump always needs a storage tank to heat the hot water. But installing a cylinder for the central heating system is also meaningful. For example, this allows you to use your own photovoltaic power generation during the day and get calories from the cylinder at night or cloudy.
4. Can the heat pump provide sufficient heat to reliably hear the winter to spend the winter?
The correct design and configuration heat pump is as reliable as the traditional heating boiler. Even in the cold winter, it will heat your home to the required temperature, and it will always provide sufficient hot water.
5. Is there subsidies for air source heat pumps?
Federal subsidies at all levels of the state, county and local levels provide support for the purchase of air source heat pumps. In order to obtain this fund, some conditions must be met when planning new buildings and should be considered in time. In addition, it provides rich funds for the modernization of the old buildings.
