New data is created for households by the energy crisis, which has significantly increased the cost of heating homes, creating additional burdens on family budgets. The changes that have taken place in terms of heating costs, depending on the technology chosen to meet the needs of households, are highlighted by a study conducted by the Laboratory of Steam Engines and Boilers of NTUA, in collaboration with the Institute of Chemical Processes and Energy Processes. Specifically, the results of the study sharply reflect the rapid increase in heating costs for the average household in Greece, at least in relation to the current time. This concerns all thermal technologies and is directly related to the energy crisis, having caused a continuous rally in the prices of heating oil, gas and electricity since the beginning of the year.
Indicative of the changes is the comparison between the current prices with the cost of heating four years ago: gas has increased by 128%, heat pump has increased by over 73%, heating with electrical appliances has increased by 59% while heating with a standard oil boiler has increased by 6.56%.
According to the NTUA study, the most expensive heating method is the device with electric resistors (electric boiler) with a power of 1200 KW, which has a thermal energy cost of 0.329 euros / KWh and is 153% more expensive compared to oil. The consumption of 450KWh / season, which is equivalent to the consumption of 516 liters of oil, costs 1349 euros, while the investment cost, according to the study, is unprofitable.
The second most expensive method of heating is the open chamber fireplaces, with a cost of thermal energy of 0.243 euros / KWh, which is 132% more expensive than the cost of heating with oil. The energy efficiency of the closed chamber (energy) fireplace with a cost of thermal energy of 0.121 euros / KWh shows better efficiency. A total of 4593KWh per season with an open fireplace will cost 1093 euros, while with an energy fireplace the cost will be 546 euros, while the amortization of the investment takes place over 20 years.
The third most expensive heating method is natural gas, with the cost of thermal energy amounting to 0.16 euros / KWh for a stand-alone boiler and 0.169 euros for a shared utility. Natural gas is 23 to 30% more expensive compared to an oil boiler. For a season and consumption of 4500KWh will need 761 euros (household utility in Attica). In terms of investment cost for this installation amounts to 3910 euros and the investment is characterized as unprofitable.
Heating with a standard oil boiler shows a cost of thermal energy of 0.13 euros / KWh and for one season of useful thermal energy 4500KWh will be required 585 euros. This amount is reduced to 404 euros if the state subsidy for the heating allowance is taken into account.
The technologies that are cheaper than heating oil are wood pellets and the heat pump.
Specifically for heating with biomass boiler (wood pellet) shows a cost of thermal energy of 0.097 euros / KWh cost by 24.9% cheaper than oil. For one season (4500KWh) 438 euros will be required, while the cost of the investment amounts to 6930 euros and is depreciated in less than 20 years.
The heat pump has a thermal energy cost of 0.061 euros / KWh and is 53% cheaper than the oil boiler. In one season (4500KWh) 263 euros will be required. The investment cost, however, is the highest and reaches 8370 euros. However, it is depreciated in less than 20 years.
