Heat Pumps

A heat pump is suitable when seeking an efficient solution for heating, cooling, or production of DHW (Domestic Hot Water), with reduced energy consumption. It is especially suitable for single-family homes and well-insulated buildings, although it can also be integrated into renovation projects. The decision should consider the type of use, the existing system, and the medium- and long-term energy efficiency objectives.

There are air-to-air heat pumps, air-to-water heat pumps and systems dedicated exclusively to the production of AQS. Air-to-air solutions are used mainly for space conditioning, while air-to-water ones can be connected to central heating, underfloor heating and hot water production. The choice depends on the type of dwelling, the existing heat distribution system and the intended primary function.At BIGAVAC, you will find various types of heat pumps that suit the different needs of the project.

Yes, a heat pump can replace a water heater or storage water heater, especially in the production of AQS. Heat pumps for domestic hot water have significantly lower consumption when compared to traditional electric equipment. However, they require space for installation and adequate ventilation conditions. The replacement should be evaluated by technicians to ensure compatibility with the consumption pattern and with the space available in the dwelling.If you need support, you can count on the professionals at BIGAVAC.

The heat pump is recommended for regular and prolonged use and is more energy-efficient. The electric storage water heater is simpler to use and install and has a lower initial cost, but tends to have higher operating costs. The decision should consider the number of users, the consumption profile and the investment time horizon. It is important to weigh the pros and cons with the support of professionals.

The power depends on the house's area, the insulation, the ceiling height, the location and the AQS needs. Generic values per square meter can be misleading. Correct sizing is essential to ensure efficiency and to avoid excessive consumption or insufficient performance. The building's technical analysis is very important in choosing the appropriate power.

Yes, it is possible to install a heat pump in an older house, provided the system is properly adapted. In older buildings, the level of insulation and the type of heat emitters are particularly relevant. It may be necessary to adjust the radiators or opt for more specific solutions. A prior technical assessment makes it possible to determine whether the heat pump will operate efficiently or if additional interventions are necessary.To clarify any doubts, contact us!

Yes, when correctly sized and installed. Heat pumps take advantage of the energy in the outside air to produce heat, which results in high levels of efficiency. Actual performance depends on the type of equipment, weather conditions, building insulation, and system regulation. Proper installation is decisive for achieving good results.

Maintenance of a heat pump should be regular, but in fact it is not very demanding. Maintenance should include checking the refrigerant circuit, cleaning filters, checking components and a general inspection of the system. Proper maintenance ensures efficiency, reduces the likelihood of breakdowns and contributes to a longer service life of the equipment. Compliance with the manufacturer's recommendations is essential for proper operation.

Yes, heat pumps are subject to regulation in Portugal and the installation must comply with technical and legal standards, which include electrical and ventilation requirements and, in some cases, the building's energy framework. Depending on the application, additional requirements may apply. Prior verification of the legal framework ensures greater safety, compliance with the requirements and proper operation of the system.
