The aroTHERM VWL PLUS 55/6 heat pump from Vaillant, with refrigerant R290, has a power of 5 kW and can meet the needs of a residence up to 50 m². It is a device that can extract existing energy from an external space and transfer it to another internal space, providing heating and cooling. To heat the space, the heat pump extracts heat from the environment and channels it into the interior of the residence to increase the internal temperature. Conversely, to cool the space, it extracts heat from the interior of the residence and expels it into the environment, gradually cooling the space.
It can be connected to a single-phase or three-phase supply, consuming a small percentage of electrical energy from the grid, drawing the remaining energy from the environment. This results in energy and cost savings, as there is no longer a need to purchase oil or wood. The use of electrical energy is only required in the heat extraction stage, not in its transfer. The ratio of energy required for the operation of the pump corresponds to approximately ¾ from the environment and ¼ from electrical power. This means, for example, that for every 3 kWh drawn from the environment, combined with 1 kWh of electrical energy required for its operation, we have a total of 4 kWh of useful thermal energy.
The technology it uses is air-to-water, meaning it uses air as a heat source and water as a transfer medium. It heats or cools the water, which is then channeled into the interior of the residence.
The system is monoblock, meaning all its individual construction elements (such as the compressor, heat exchanger, fans, etc.) are integrated into one unit, which is placed outdoors. This offers you ease of installation and direct connection to the water system.
It is considered high-temperature, as the system's water temperature can reach up to 75 degrees Celsius, and its ideal combination is with classic radiators, which are already installed as a heating system in the building, as they do not need to be replaced with new ones. It is an ideal solution in case of replacing an old boiler, as it produces high-temperature water, just like the old one. It can easily be integrated into existing piping and radiators without needing to replace the entire system.
The pump can optionally accept a tank to produce hot water for use throughout the year. The tank is not included and must be purchased separately.
Finally, in any case, the recommendation for the most suitable heat pump based on needs is made by an experienced engineer. After a study, they will recommend the appropriate pump that will offer maximum efficiency with the lowest annual operating cost.

If you choose a heat pump with greater power than what the building where it will be installed needs, aside from the higher initial cost of purchasing it, it will be forced into continuous restarts, resulting in the pump being strained and the operating cost increasing.
