A complete energy saving guide, 23 points, has been published by the Ministry of Environment and Energy.
Three subsidy scales for electricity, up to 485 euros and a bonus – 90 euros for natural gas

The instructions of the Ministry of Energy for reducing energy consumption are as follows:
- Isolation of unused spaces.
We close heating bodies and internal doors (if any) leading to corridors or near stairs. So we close off natural air passages so they can’t act as chimneys, allowing warm air to escape through the house.
2. Free radiators.
The radiators must not be covered, e.g. with covers, or to obstruct their performance by furniture.
3. We seal doors and windows.
We install insulating tapes or curtains. According to studies (DOE), when drawn, curtains can reduce heat loss from a hot room by up to 10%. We can also put films on windows and balcony doors or only in rooms we don’t use.
4. We check the insulating rubber on the doors of refrigerators, freezers and ovens, so that it makes good contact and there is no loss of energy (loss of cooling).
5. We limit the time we leave the refrigerator door open.
In this way we minimize the temperature recovery time (loss of cooling, radiator light), thus reducing consumption from motor operation.
6. Adjust the thermostat.
– The cooling system of refrigerators and freezers at a higher temperature.
– The water heater at lower temperatures.
– The air condition (if we leave it open) during the hours of our absence from the house at a lower temperature. Also, during sleep we can reduce the temperature by up to 2 degrees.
7. Placement of household appliances (e.g. refrigerator, freezer and clothes dryer) away from heating sources.
8. We wash our clothes in the washing machine at low temperature.
9. Closing Devices when in standby mode.
10. When we don’t use the fireplacethe chimney must be closed by its shutter.
11. Close the oven for 10-15 minutes before the cooking is finished, as the heat present is sufficient to prepare our food.
12. Cooking utensils they must fit well in the eyes of the kitchen.
13. Whenever possible, we use a pressure cooker when cooking.
14. We lower the brightness as much as possible on devices with screens (eg PCs, TVs).
15. Installation of a programmable thermostat.
A programmable thermostat allows different temperatures to be preset for different times of the day. A programmable thermostat saves money on both air conditioning and heat.
16. Installation of thermostatic valves on radiators.
They allow the automatic adjustment of the flow of hot water according to the desired temperature of each room separately. They are installed locally on each radiator separately and they progressively regulate the flow of hot water. Thus, each heating body becomes independent and is automatically isolated when the desired temperature is reached, while the rest of the spaces that need heating continue to operate.
17. Installation of compensation system in the boiler.
18. Heating/cooling system maintenance,
e.g. boiler, heat pumps, air conditioners.
19. Installation of a solar water heater.
20. Replacement of Devices with high energy efficiency devices based on the energy labeling framework and EnergyStar specifications.
21. Replacement of light bulbs with LED technology.
22. Replacement of the existing frames with new, heat-insulating-energy ones.
23. Installation of an energy management system.
