LITHUANIA – CONSTRUCTION
When looking for new housing, experts recommend choosing not only houses, but also flats with aerothermal (air-water) heating. Although there are currently not many apartment buildings heated in this way, there is no doubt that this type of housing will prevail in the near future.
This heating system is extremely low-polluting and cost-effective because the heat pump, located outside the building, absorbs heat from the outside air and transmits it to the room through the installed heating appliances: underfloor heating, radiators and other heating devices.
“Obviously, the future is renewable energy sources. Almost all manufacturers are building new plants in Europe to meet the huge demand for aerothermal heating systems. As the production of solar and wind energy grows in Europe, as well as in Lithuania, it will become one of the most cost-effective ways of heating. Because more and more of the initial fuel needed for this system – electricity – will be self-produced. This makes it a rational and promising choice for current home buyers,” says Viessmann sales representative Marius Digris.
In addition, the electricity requirement for this heating system is relatively low. This makes users practically independent of external suppliers, whereas with gas or solid fuel heating this dependence is practically 100%.
Aerothermal heating has a number of other advantages. In summer, heat pumps can be switched to cooling in some systems. In addition, they are reliable and long-lasting, with a service life of about 15 years.
The only problem is the cold winters
Perhaps the only problem is cold winters when temperatures drop to -20 C or more.
“In these cases, the temperature differences are quite large and the right power balance must be chosen, so aerothermal heating can be combined with an additional heat source, such as electric heating. However, the additional heating should not constitute more than 5% of the total energy consumption,” says Mr. Digris.
Real estate developers in Lithuania are increasingly turning to aerothermal heating for new high-rise construction projects. One such company is Centromera, which has been operating in Kaunas for almost 20 years. According to Vaida Šidlauskienė, deputy director of the company, eco-friendliness of housing is already an important characteristic, which will become more and more important over time.
“When designing comfort flats, we take into account the latest trends and existing best practice so that they are cost-effective for the buyer, but at the same time meet high standards.
Since housing is a long-term asset that will last for decades, when choosing a new home, you should already consider the technical features that will be taken for granted in the future. It is worth noting that banks and credit unions also encourage the purchase of green homes (A++) by offering lower interest rates,” said V. Šidlauskienė of Centromera.
