Heating system : the importance of a good maintenance

At the time of the energy saving, it is important to ensure the correct operation of a heating system. Often, however, scale, corrosion and sludge come block the circuit and impact the performance of the system. What are the ways to prevent it ?
63% of heating systems use water as the fluid peddler, reminds Best Water Technology (BWT). Hence the importance of ensuring its quality. Because with time, corrosion, slush and tartar come to spoil and clog the network with more or less severity. As many of the risks that impact the energy efficiency and result in failures, over-consumption of energy… “For installations which are claiming over 100% efficiency, 1 mm of pie is enough to bring down performance to 76%, if the situation lasts”, explains Sophie Vatin-chaix, responsible activity SoluTECH in BWT.


Thermal regulations concerning the levels of consumption, mean that the choice is made on high efficiency equipment which, if subjected to these risks, lose in efficiency. “With the RT2012, we ask to consume 10 times less power than 30 years ago,” says Sophie Vatin-chaix. But in France, there is currently no requirement for water treatment of heating and 80% of facilities are not addressed. Below are a few points to take into consideration to keep a heating system performance.


Identify malfunctions


If it is advisable to call a professional to fix the problem, prior to this, the individual can identify the symptoms and dysfunctions. Here are some cases that should worry you :


– Heaters and boilers that emit noises
– The issuers are cold in places
– Colored water, or a muddy lot at the purge
– A house does not warm up, so that the heating runs at full speed


Find the cause of the failure


The origins of the dysfunctions related to water are multiple. Due to its composition, it can drop the lime, puncture, or embouer a circuit. Its acidity and its alkalinity fall online account, as well as its concentration in minerals (sulfates, carbonates, chlorides, etc.). All causes that can lead to corrosion and entartage.



The presence of oxygen in the water, it comes oxidize the metals. In addition, the temperature of the water in a heating system is a : “low temperature, almost bodily. This promotes the development of micro-organisms”, in advance Sophie Vatin-chaix. So many elements that generate mud and sediment deposits that clog and block the ducts, valves, pumps, thermostats and impact the throughput and energy performance.


Put in place the appropriate solutions


To avoid such problems, several solutions are available to the individual. It can, itself, collect the water and send it to a laboratory for analysis. It is to be noted that it is necessary to take the make-up water (city water) and the water heating circuit, for a complete analysis.


If the system is touched, an operation of the de-sludging can be applied. A professional injects a treatment into the circuit that disperses sludge, oxides and tartar (according to BWT, the doses are insufficient to present a risk to the environment). The installation is then drained, rinsed, and then filled with new water. The water is precisely controlled to ensure its compatibility with the materials for example. Preventive Aspect requires, in addition to the problem, what are the causes that need to be addressed. Thus, at the end of the operation, the professional will inject another treatment to avoid any recurrence. “An individual who has the knowledge, technical resources are able to do this itself (rare case). But it is better to entrust this task to a professional, “advises Sophie Vatin-chaix. In other words, do-it-yourselfer Sunday, refrain.


Prevention and prescription


BWT reminds us that this is the installer’s heating engineer to recommend the operations are adapted, when a replacement boiler or annual maintenance, for example. Whether it’s a new installation or old. But in reality, its role is generally limited to the board and there is nothing that requires the individual to follow it.
