Õhk-vesi soojuspumbad is a highly efficient method of heating your home. They use the air outside to generate hot water, which can then be used to power central heating systems as well as provide domestic hot water. But with so many different types of air-water heat pumps available on the market, it can be difficult to know which one is right for you. This article will explore the various types of air-water heat pumps, the advantages, and disadvantages of each, and provide tips on how to choose the best one for your needs.

Split Type Air-Water Heat Pump

Split-type air-water heat pumps are one of the most common types of air-water heat pumps available. They consist of two parts – an outdoor unit (the compressor) and an indoor unit (the evaporator). The compressor extracts warm air from outside and transfers it into the evaporator, where it is heated up using a refrigerant before being sent into your home’s heating system or hot water tank. Split-type air-water heat pump systems tend to be more expensive than other types but they offer high efficiency levels and are relatively easy to install.


• High-efficiency levels
• Easy installation process
• Flexible placement options


• Expensive initial cost
• Potential noise issues due to the outdoor compressor

All-in-One Air-Water Heat Pump System

All-in-one air-water heat pump systems combine both the compressor and evaporator into a single unit, making them easier to install than split-type systems. As all components are contained within one unit there is less risk of noise disruption either inside or outside your home. All-in-one systems also require less maintenance than split-type models as they have fewer moving parts that need servicing regularly.


• Quieter operation
• Low maintenance requirements
• Easier installation process


• Not as flexible when it comes to placement
• Lower efficiency levels compared with split-type models

Ground Source Air-Water Heat Pump Systems Ground source air-water heat pump systems extract energy from deep underground using a series of pipes known as ground loops. The ground loop absorbs warmth from deep beneath the surface before transferring this warmth via fluid into a central manifold located at ground level near your home. From here, the warmed fluid is passed through an exchanger which transfers its stored energy into your home’s radiators or hot water system via a traditional boiler or immersion heater circuit. These systems tend to be more expensive than other types due to their complex installation processes however they offer excellent efficiency ratings which make them worth considering if budget allows.


• Very efficient operation
• Little maintenance required


• Expensive installation costs
• Complex setup process

Which Air Water Heat Pump Is Right For You?

When choosing between different types of air-water heat pumps consider factors such as price, ease of installation, maintenance requirements, and overall efficiency levels before deciding on what suits you best. If you’re looking for something simple yet effective, then all-in-one units may suit you better whereas those who require higher performance should opt for split-type models instead. Ground source systems are ideal for those who want maximum performance but must bear in mind their high cost when making their decision. Ultimately though it depends on personal preference, so take some time researching each option before investing in any particular model
