One An 11-year-old child He was killed at school, while he was working full-time and playing with friends in his school yard. The unimaginable event scarred the body – and perhaps the soul forever – of two other minor children, students of the same school.
For what happened that day Ceres It is because of the explosion inside it Boiler roomThe one who untied her Metal door 40 meters away, before crushing the child.
Since then, a ping pong of reports began between the municipality, the school and the technical service that worked on the boiler as to who was to blame.
I won’t tell you what each side supports (they mostly blame each other), because that would spoil the child’s memory.
At the same time, the family of an 11-year-old boy tries to manage something the human mind refuses to comprehend: the loss of a child in a place that should feel safe.
Pay the hard way Defects and errors Others.
The lawyer’s intervention was immediately ordered and its experts were seen at the school Hellenic PoliceTo elucidate the causes of the fatal outbreak.
They were arrested At the school, the contractor and electrician of the project to convert the heating burner to a geothermal heat pump Categories Offenses of negligent homicide, negligent grievous bodily harm and negligent explosion.
They were released shortly after A case was registered against them.
After the investigation, Prosecutor’s Office of Ceres He will decide the criminal liability. It is not excluded that other persons may be included in the case record.

Guess what You have a hard time understanding (because you still have a hard time accepting) that a child was killed at his school. Boiler explosion.
It is confirmed that the work is in progress. Who approved them – during the lessons – who carried them out and what they did wrong we will find out as the case progresses.
As a first step, Giorgos Kotsenpapas, president of Ceres Burner Maintenance Companies, said in a press release. Star The explosion occurred during the visit of technicians who were going to repair the geothermal pump and how “They closed the valves of the boiler without protecting the burner”. When the boiler was turned on for some reason – thermostat, switch or human hand – it ‘exploded’..
I guess I’m not the only one who doesn’t quite understand what all this means.
The magazine Contact thermo-hydraulic Costas SulphidisMr. It needs to be clarified what Kochanbabas is referring to and whether there is any basis for his claims.
“As mentioned, the school used to have an oil-fired boiler and two years ago it was switched to a single system Geothermal – Insulation of old boiler.
Geothermal does not automatically support heat – it has low temperatures.
It must work with some other power source. That is, with a heat pump or a new oil boiler.
In larger units with central heating (such as schools), the boiler has a burner thermostat that ‘checks’ the temperature without raising it too high – opening and closing accordingly.
Boilers also have some timers that ‘give’ the order so that they ‘take’ ahead and operate at a specific time.
Each boiler has two valves: inlet (sends hot water to the bodies) and return (returns cold water from the bodies).
If you don’t close these valves and the boiler goes forward, it will ‘pop’. If you close them, it won’t pop.
Generally, boilers have several safety valves.
has Burner thermostat As we have already explained, the Safety heat is in the boiler and if it ‘senses’ something is wrong – the water evaporates – it shuts down the entire circuit. Safety valve About the water circuit (see valves). It works like a pressure cooker: when there is a danger of an explosion, it turns off the boiler.
The first two are electric and the third is hydraulic
Someone must have isolated these valves to do what was done in Serres. Otherwise, the eruption is not explained. In other words, someone shut off the water circuit.

I believeWhat’s worse is that at this point you think it’s impossible for the technicians – that a child lost their life over such childishness. All the evidence will be available to us once the result is out.
Until then, I’d also like to share what’s going on at the Special Municipal Tower. Handicap toilets have a burner and oil tank. In this regard, the employees complained several times, but no one responded from the local administration.
Next, I would like to draw your attention to something that worries us all: individual natural gas boilers on many balconies.
In recent years, related explosions in apartment buildings have been on the rise, with experts stressing the need for annual service.
Mr. As Sulfides says, only a few do.
The required annual technical inspection should be somewhere in the 5%. Generally, we are called when there is a problem with an individual unit. In this case they are asking to fix what is broken.
This is obviously a matter of cost (the service with VAT is around 80 euros).
However, who does not respect the prerequisite of the manufacturers of these units?
“Firstly, the boiler is constantly making ‘production’ faults, so it doesn’t heat up before it becomes unusable.
Technical control is also done on the safety valves of the boiler, a safety system to avoid unfortunate events – such as explosion.
A check is made on the water circuit and a leak test is made on the natural gas combustion chamber: it is in a very closed place, where even oxygen does not pass, but it is covered with rubbers, which must be replaced at some point. No gas leakage.
This is the usual cause of explosions: gas leaks.
As soon as the boiler gives off a spark – it doesn’t sense a leak – the explosion comes”.
The second most common cause of explosions is overpressure, and the third is weakness of the system “The manufacturer also indicates the insurance network that should be changed every year”.
However, this is becoming rarer than complete services.
“It’s also wrong that the customer is not told what he needs to do every year and what happens if he doesn’t do it.”Before adding that Mr. Sulfides explains “Just as air conditioners require maintenance each year, so do individual natural gas boilers.
By the way, this money is not saved by the owner, because he will pay for the aforementioned consumption charges anyway, since the boiler will not work optimally, the technicians will not have made arrangements for it. Correct Function”.
How likely is an explosion if we are careless? “Typically, it’s very difficult to cancel all insurance systems for a boiler to blow up. To disable the entire electronic system. The chances of problems increasing as the years go by are still not serviced by us.”
What saves us in Greece is that we put the boilers mainly outside – they are ventilated. In other countries they put them inside houses, they trap gases and create problems”.
That means more problems for reasons not just about negligence – as we demonstrate here in Greece.
