No one is ever prepared for a heating failure, especially in winter. The resulting interventions can take too long to set up and can be labour-intensive. Is it then more economical and quicker to make these few repairs to your boiler yourself? Nothing is less certain.
What you need to know
A boiler is a heating system that requires regular attention to last over time and cannot be repaired without technical knowledge. Since June 9, 2009, it is mandatory to call a professional for the maintenance of its device. Failure to perform this check does not result in any fine. However, it can serve as a justification for your insurance not to pay for your repairs if an incident occurs.
Nevertheless, a private individual has the possibility of doing some small work that will save him money and time.
Do the checks yourself
In order to prevent the slightest incident, a few checks can be made by the owner of the device.
Check that the boiler pressure is between 1 and 2 bars. A small needle normally indicates this on the front of the system. If it is lower than 1, depending on the model, it is possible to increase the water flow rate to restore comfort. In the case of higher pressure, purging the radiators may be the solution. If nothing changes, call a professional.
The problem may come from an accumulation of mud or other deposits in the pipes.
If the boiler tends to stop and restart untimely, it may be due to a problem with the thermostat. If the latter is connected by radio, bringing it closer can possibly solve the problem if the connection was not optimal. A lack of water circulation can also be the source of the complication if one or more radiator taps are closed. In this case, simply open them.
Finally, too much power can also be the cause. The boiler will therefore have to be restrained. If the situation does not get better, this requires more skill, then a qualified craftsman must be called in.
In the event of a leak, several situations are possible depending on the flow rate of the boiler. If it is in the form of small droplets, it may be a loose pipe or a worn joint. Two cases that can be easily solved without any skill. If the quantity of water escaping is large, it is imperative to contact a professional as soon as possible.
When the days are particularly cold and the boiler stops suddenly, this may be due to the freezing of the condensate tube. In this case, simply remove the layer of frost and the system will resume its initial functions.
If neither hot water nor heating is produced by the appliance, the circulator should be checked. The circulator may be blocked, in which case, simply refer to the manual to put an end to the problem. If the various operations do not solve the problem, contact your heating engineer.
The dangers of self-repair
Repairing your boiler yourself without any knowledge or experience is very difficult. The technical documentation of the appliance may be complete, but nothing can replace the expertise of a professional
Apart from minor checks and adjustments, carrying out an intervention on your system is risky and will tend to make a simple case worse. Not to mention that the failure of the operation will be your sole responsibility and unfortunately you will not be able to obtain a refund or repair for your own error.
Unless you are a craftsman officiating in the field of heating, self-repair is an operation to be limited as the consequences can be costly.
In order to prevent the slightest incident, taking out a maintenance contract is a solution that ensures the operation of a boiler over time. Such an offer makes it possible to comply with the law and to be covered by insurance in case of problems.
Usually offered the first year after installation, the maintenance contract grants travel and labour in case of breakdown.
