If you experience a major boiler failure, you should obviously call a heating plumber quickly, to make sure everything is in order. However, some small malfunctions may be resolved very easily, without specific knowledge or tools. Thus, to save the cost of a craftsman trip, we take stock of the main interventions that you can do without risk while encouraging you to seek advice when you have the slightest doubt. For the furnace repairs this is essential now.
Cold radiators: modulating the water flow
If your radiators are lukewarm or completely cold, it may simply mean that the adjustment of the water flow rate at the boiler level is not correct. Here, you just need to look at the data displayed on the control panel, and adjust the settings if necessary. If you do not know what the values are, take the time to read the information in the user manual.
For example, for a gas boiler, the pressure of the pressure gauge must always be between 1 and 2 bars. For better efficiency, it is also recommended to perform a manual bleeding of the radiators.
The boiler goes out: several checks to be made
If your boiler switches off by itself for no reason and repeatedly, you can perform a few tests before calling a professional. For example, in extreme cold, the condensate tube can be frozen simply remove the gel layer to return to normal operation. Again, the presence of too much air in the radiators can also be responsible for successive shutdowns of the boiler, which may also require purging of all connected devices.
Water leak at the boiler: what to do?
Depending on the extent of a water leak, we do not necessarily react in the same way: if yours loses large quantities of liquid, you must quickly call a professional to avoid the situation getting worse, not to mention obviously to cut the food, so as not to experience water damage in addition. On the other hand, for a slight “drip”, first try to find the origin, to see if there is not simply a badly connected pipe or a joint which is missing. When the leak comes from the bottom, the safety valve is usually the cause. If it is necessary to change the resistance gasket, for example, we suggest that you call a professional.

The hot water pressure is very low
If you find that your hot water pressure is not high enough, first check that you are still between 1 and 2 bars in terms of the general operation of the boiler. On some models, it is enough to manually add water (by opening the tap) to increase the flow rate and find a better supply of hot water when showering, for example.
However, this kind of malfunction can also come from an accumulation of scale or dirt in different parts of the boiler. It will therefore be necessary to call on a professional for a complete cleaning, in order to regain the initial performance and to avoid total breakdown.
