Not everyone knows the cooling function of this device: it helps to withstand the summer heat.

Delfi Būstas has already written about the parameters to take into account when choosing an air conditioner, how to use it so that this device does not cause colds. Those who still do not want to install an air conditioner in their home have another option: the cooling function of geothermal heating systems. According to Mindaugas Budrys, Sales Manager of UAB TENKO Baltic, the principle of operation of a geothermal heating system is based on the fact that in winter the heat pump takes heat from the depths of the earth, which heats the house, and in winter summer this The device can cool it down. In some cases, this feature can be installed on already installed systems.

“Heat pumps can have a built-in cooling function, customers generally choose units that have this function, but depending on certain heat pump manufacturers and models, the cooling can be installed in an existing system that was not designed for cool. It is only important that the heating and in this case the cooling system in the premises is suitable for this purpose, the floor, the ceiling heating system or the fan convectors are generally used for cooling.
If a floor or ceiling heating system is chosen without cold, there is no air movement or noise, so the indoor climate is especially comfortable, cool and pleasantly cool, and this system requires practically no maintenance ”, explains the interlocutor. It continues that the heat pump compressor does not start during cooling, only a few circulation pumps are circulating (circulating the liquid in the system), so the operation of this system is extremely economical, only 15-20 euros they are sufficient throughout the summer season.

What is geothermal heating?

Geothermal heating is just one of the possible heating options for homes. Geothermal heating systems are an environmentally friendly way to heat a home. How do these systems work? The heat is taken from deep in the earth and used to heat the house and prepare hot water. However, one of the key questions for all newcomers is how much home heating costs with underground heat and if such heating is sufficient to meet the needs of the whole family. For example, if the field is 30 degrees below zero or 120 square meters. m for the house is enough only the heat from the depths of the earth? M. Budrys affirms that the efficiency of this system does not depend on the external climatic conditions (the heat source is the energy of the ground), reason why practically all the year the system works of especially efficient way.

“The information collected shows that consumers operating geothermal heating systems calculate an annual efficiency of 4.0 to 4.7 (4.0 to 4.7 kW of heat is produced from one kW of electricity consumed). For example, these results are around 20-30%. more efficient compared to the growing popularity of air-to-water heat pumps, which also impress with their efficiency, but with the potential to save between 20% and 30%. Electricity costs and expenses are an important factor that can determine the decision to choose a geothermal heating system ”, emphasizes the interlocutor.

According to Budri, when it comes to geothermal heating systems, it should be noted that one of their advantages is cleanliness: there are no solid fuel boilers in the house that need to be cleaned.

How much is it good for?

How long do geothermal heating systems serve? According to M. Budris, the heat pump, which absorbs heat from deep in the earth, has a long service life, because this system has a non-combustible process (without combustion process, the equipment is not exposed to external climatic conditions , etc.), so in the long run this system is more economical.

It is true that geothermal heating systems also have their drawbacks, such as the earth movements required to install the system, usually even when the house is still under construction. Also, a geothermal heating system does not affect the wallet of all newcomers.

“Since these works are still being carried out in the field, it is more complicated when the building is in operation and the well-being is already in order, then care must be taken that these works are carried out in a particularly cultural environment. way. Another disadvantage is the higher initial investment ”, says the interlocutor, adding that the cost of installing geothermal heating depends largely on the heat demand of the building and the type of soil collector chosen. The higher the heat demand of a building, the more powerful heat pump is needed.

A separate room is required

The installation of geothermal heating systems requires a separate but small space of 2 square kilometers. m in size, local. It is also very important to choose the right heat source and equipment, which is quite compact, in many cases, according to M. Budris, it is possible to compare the size of the heat pump with the refrigerator.

“It is important to note that the heat accumulated in the soil is collected by specially equipped soil collectors: horizontal (the pipe is led to the ground below the freezing zone, generally at a depth of 1.4 to 1.7 meters) or vertical (the pipe is fed to a specially equipped well) “, interlocutor.

Those newcomers who care to be at least something similar to a smart home should take care of an additional equipment: a phone and a wireless Internet connection. In this case, a number of heat pump functions can be controlled via the app, such as monitoring the heat pump operation, adjusting certain settings, regulating the temperature, etc. In addition, if you have questions about the operation of the system, the pump connected to the Internet can be monitored by equipment specialists, who can verify that the equipment is working properly, remotely adjust the operation of the pump, or perform other troubleshooting work. problems.
