Guide: How much will the heating of the house cost this year – Prices for oil, natural gas, air conditioners, fan heaters

With energy prices “burning” and the country moving towards winter more and more people are wondering what is the most efficient and profitable way to heat a home this year.

The equation this year is more difficult than ever, according to experts. The starting prices of heating oil were increased by 45% compared to last year, natural gas increased by up to 200%, while electricity follows the same path. But how do all these increases translate into euros? How much will heating cost for an average household this year?

“Heating oil and natural gas are still the two main fuels for the vast majority of buildings in Greece. This year there are two important developments. The first is the increase in cost in absolute terms. “Secondly, while until last year there was a given difference in heating costs between heating oil and natural gas of the order of 20%, in favor of natural gas, at current prices this difference is almost zero”, says Mr. in Agis Papadopoulos , professor of energy systems at the Department of Mechanical Engineering of the Aristotle University of Thessaloniki and president of EYATH.

Heating oil vs natural gas
According to Mr. Papadopoulos, the comparison between the heating means should be based on the kilowatt hour of heating. Last year, as he says, “for a kilowatt hour of heating with oil you needed about 8 cents and with natural gas 6.5 cents. That is, for an average house in Thessaloniki, ie relatively thermally insulated and with an area of ​​85 sq.m., 450 euros would be needed for natural gas and around 550 euros for heating oil “.

With this year’s prices, however, the scene is changing. “This year, for the same apartment, 650 euros should be given for heating with oil and 650 euros and… something for natural gas. Therefore, the difference of 20% to 21% that existed last year in favor of natural gas, this year does not apply. They are equivalent prices “, underlines Agis Papadopoulos.

According to announcements made a few days ago by the president of the Association of Petroleum Trading Companies (SEEPE) Giannis Aligizakis, the latest data show that the price of natural gas is 0.974 euros per kilowatt hour compared to 0.955 for heating oil.

The alternative: How much will it cost to heat with air conditioning
The above data may cause “terror” to consumers. And the first thought of some will be to turn to their air conditioner.

According to Mr. Papadopoulos, the only alternative that is realistic – as citizens can not change every year depending on prices, from gas to oil – is that of electricity, ie the use of air conditioners. Nevertheless, he estimates that “with the prices of electricity rising due to the increase of gas I am afraid that next month will show a similar increase in the cost of using electricity.”

The solution of the air conditioners would be excellent if the cost of electricity remained at the levels of 2020. in Thessaloniki. “With last year’s prices, in order to heat two to three main areas of the house with two air conditioners, the annual cost would be 400 euros”, notes Agis Papadopoulos.

“Electricity prices, however, follow the” race “of gas and are gradually rising. “Although we can not make a safe prediction of where they will end up, we could say that the cost of heating this year for the same house with air conditioners would be 550 euros,” he explains. This is a very “explosive” increase, of the order of 35%.

Is it worth turning on the fireplace or stove?
The impasse that arises worries experts, as it is not excluded that many people with low incomes turn to precarious heating means, such as makeshift stoves. This trend caused loss of life in the harsh memorandum years damaging the environment as well. However others may “remember” other alternative means such as the fireplace, stoves or even the cheap – only in terms of purchase price – fan heaters.

“A common fireplace has a rather poor performance perhaps the worst possible. Citizens should also keep in mind that firewood prices follow oil prices because transporting timber requires fuel. So I would say that the fireplace is not a good choice and could only be considered by someone who has very cheap access to wood. “If we are talking about an energy fireplace again, then yes, they have a much better degree of efficiency”, points out Mr. Papadopoulos.

On one “step” above for their thermal efficiency are the stoves. “Stoves, especially cast iron ones, radiate a lot of heat, they heat the space very sweetly. And the cast iron lasts for hours. And in this case, however, as in the fireplace, these media have significant losses. The heat escapes with the exhaust gas from the chimney and, in addition, they are local heating systems. That is, you heat a smaller space “, he adds.

Air heaters and electric stoves and radiators against air conditioners
Equally careful should be those who remove the “traditional” fan heaters and electric stoves and radiators from the lofts and closets.

According to Mr. Papadopoulos, there are no significant differences if one has an electric stove or a fan heater or a halogen stove. As he explains, “if the device is 2,000 watts, then we calculate two kilowatt hours. If we consider even with summer prices that for one kilowatt hour with the regulated charges the cost is at 14 to 15 cents then for such a device the operating cost for only one hour will be 30 cents or more “.

In terms of air conditioners an average type of 12,000 btu is about 900 to 1,000 watts. “For example, let’s say it has a consumption of 1kW. In this case it burns one kilowatt hour, ie it costs us 15 cents per hour. However this air conditioner heats an area of ​​25 square meters while the fan heater is limited to a radius of one or one and a half meters ” concludes Mr. Agis Papadopoulos, professor of energy systems at the Department of Mechanical Engineering of AUTh and president of EYATH.
