The heating system

With regard to the heating system of houses, the conditions of a beautiful day in spring should be created, 20 degrees centigrade, humidity about 50% and good circulation of air:

  • only slightly heat the rooms that are not used at all, or which are used rarely;
  • during the day, keep the temperature at 20 degrees centigrade, at night 16 degrees centigrade (1 degree less is equal to  5-7% savings) and however respect the limit set as maximum temperature inside the house and the period of the season in which the heating systems can be turned on, which are both regulated by the different Town Councils;
  • in the evenings, close the shutters or lower the shades and close the curtains, unless these also cover the radiators;
  • during the day do not prevent the sun’s rays from shining through the windows;
  • do not  cover the radiators with furniture, curtains or other objects ( 40% of the energy is wasted);
  • always place a board made of isolating material between the wall and the radiator;
  • ventilate the rooms shortly but thoroughly, open the windows for a few minutes only, two or three times a day;
  • apply sealing materials on the windows wherever the cold draft comes through the windows;
  • isolate the attic;
  • use isolating materials to cover the pipes that bring hot water from the boiler to the radiators;
  • mount thermostatic valves on the radiators to control the flow of hot water depending on the temperature that is recorded in the room;
  • check the boiler at least once a year and at the time of purchasing a new heating system, choose the highest efficiency boiler (by improving the performance, 10% of fuel can be saved per year);
  • if the heating system needs to be changed, prefer systems that use renewable energy sources (biomasses) or assimilated systems  (cogeneration and district heating), or methane gas;
  • in apartment buildings with central heating systems, install a system to account  for the heat utilized by each apartment. In this way it will be possible to share the expenses among the various users, in proportion to the amount utilized by each.
