FRISQUET Air_water heat pump
Heat pumps can be split into three main types: air source, ground source (geothermal), and water source. The type you choose will depend on factors such as the heat source(s) and installation space available, the existing heating systems, and your budget.
Air source heat pumps extract heat from outdoor ambient air and transfer it indoors. They can be air-to-air or air-to-water.
Air/air heat pumps transfer the heat to interior air handling units, which blow the air directly into one room, or into different spaces via a ducted system. They can be used in reverse as air conditioners. They are an economical and easy-to-install choice for small homes, apartments, and commercial spaces but cannot be used for hot water heating.
Air/water heat pumps transfer the heat from the air to a wet central heating system such as hot water radiators or underfloor heating. Some models can also be used to heat domestic hot water. Although air-to-water heat pumps tend to be more expensive than air-to-air, they are a popular choice for buildings with existing central heating systems because they can be easily installed and do not require ducting or air-handling units. Be sure to choose a heat pump that is compatible with the existing heating installation. For example, check whether it is a high-temperature or low-temperature system.
ROTH water-to-water heat pump system
Geothermal heat pumps use a heat transfer fluid such as antifreeze and buried pipes to extract heat from the ground. The heat transfer fluid is then compressed through the heat exchanger to transfer the heat to the heat pump. They tend to be very efficient because the ground temperature stays more stable than the air temperature throughout the year. However, installation can be costly and the depth and surface area of the ground required for it will depend on the heating and cooling needs of your space. It is best to get professionals to calculate this. For ground/water systems, the heat is transferred from the heat pump to the heating system and/or domestic hot water system.
Water source heat pumps work in a similar way to geothermal systems, except the pipes are submerged in a body of water such as a lake, river, or pond. If the water is close to your property, this might be easier to install than a buried geothermal system. For water/water systems the heat pump transfers the heat to the central heating system and/or domestic hot water system. Water source heat pumps tend to be more efficient than air source heat pumps because heat transfers better through water and large bodies of water tend to hold a more stable temperature throughout the year.
