The main heating and cooling systems used in buildings are usually the central heating system (with oil or gas) and A / C air conditioners (hot and cold air). These systems are energy consuming and therefore we need to be aware of their operating characteristics so that they do not consume unnecessary energy.

Central Heating Systems

The most common central heating system is low temperature hot water. In these installations a boiler is used which heats the water circulating in the radiators by burning oil.

The most important step for saving energy in these systems is proper and regular maintenance and adjustment of the boiler / boiler system, as this ensures high system performance. Maintenance should be carried out by a properly trained maintenance technician at least once a year, at the beginning or at the end of the winter season and in accordance with the manufacturer's instructions.

Periodic ventilation should be done to improve the efficiency of the radiators. The vent is designed to remove trapped air that does not allow water to circulate freely. This is easily understood since part of the surface of the radiator (usually the top of it) is cold in contrast to the rest of the surface which is warm.

The efficiency of the body can also be improved by periodically cleaning its inner fins with the help of a special brush

In order also to reduce unnecessary waste of energy, the operation of the system should be automatically controlled by an internal room thermostat. The system thermostat should be located in a location representative of room temperature and not near radiators or other heat sources that may interfere with its operation and be adjusted to the lowest possible temperature that satisfies tenants' comfort conditions. Usually a setting at 20 degrees Celsius is satisfactory. The programmable thermostats also allow for the simultaneous programming of the system operation period and the desired temperature for each period.


Did you know that ...

Over a period of eight hours of operation of the heating system, for each degree of temperature you lower the thermostat, you achieve a 2% reduction in energy consumption.

In some cases and especially in places where there are no thermostats installed, it is necessary to use thermostatic valves in the radiators. Thermostatic valves regulate the circulation of hot water in the radiator according to the room temperature in order to avoid overheating.

It is also important to immediately detect and correct any water leaks from the system and to insulate hot water pipes, especially those exposed to the external environment.

There are also many other ways to save energy on heating systems, which do not require any extra financial burden but only concern the correct behavior of their users.


Air conditioning / cooling systems

Air conditioners should always be selected taking into account their energy efficiency and space requirements. Given the widespread use of air conditioners, especially for space cooling purposes, high energy efficiency air conditioners provide significant energy savings.

In addition, the INVERTER system selects the appropriate operating frequency of the air conditioner by varying its cooling / thermal efficiency according to the needs of the space, thus saving significant amounts of energy.

The efficient operation of air conditioners is always related to their proper maintenance by a trained repairer. With regular maintenance we can identify the causes of damage in a timely manner, keep the system running at maximum energy efficiency and extend the life of the machines.

Regular cleaning of the filters is also important for the proper functioning of the air conditioners. The filters should be cleaned once a month. The process of cleaning them is very simple. Filter cleaning is also recommended for health reasons.

It is also important to immediately detect and correct any refrigerant leaks, replace any damaged insulation in the pipes, and seek immediate assistance from experts in cases of problems with their operation. 

For cooling purposes, it is also worth exploring the possibility of installing ceiling fans instead of air conditioners. The ceiling fan cools down while consuming little energy (as much as a common light bulb). Window shading also contributes to the cooling of buildings. 

There are also many other ways to save energy on air conditioning systems, which do not require any additional financial burden but relate solely to the proper behavior of their users.
