Why should we include QUADROMAG – a magnetic dirt separator in our system? Is it worth investing? QUADROMAG magnetic separators are installed in all boiler installations, to protect your new device, as well as the entire system. Many of us have this device installed on the advice of an installer, but few of us know why such a device is actually needed, what it actually does to the system. Today, the manufacturer’s warranty for any boiler is conditional on proper use and protection of the appliance, for which the QUADROMAG filter is needed. The first step is to install a mechanical dirt filter and a magnetic filter on the return line before the boiler, which is especially important in the case of condensing boilers installed on an existing radiator system, but also with underfloor heating. These two filters can be combined by purchasing a combined QUADROMAG magnetic filter, which combines the functions of a mechanical dirt filter and a magnetic dirt separator into one filter.

To understand the need for the QUADROMAG filter, let’s mention some possible malfunctions without its presence in the system:

  • Heat exchanger leaks. This is the worst possible scenario, as replacing the heat exchanger can cost up to 300-600 EUR (depending on the type and brand of the boiler), at which point it is already worth considering buying a new one. This happens because impurities and iron oxides circulating in the system settle on the inner surface of the heat exchanger, which leads to higher heat absorption in this area. This will cause the filling to burn out, weakening the material and burning out the heat exchanger at this point. In other cases, it becomes clogged, which prevents the flow of liquid. In this case, the circulation pump and the heat exchanger gradually fail, often all at once.
  • The circulation pump fails. According to the new EU directive, the three-stage pumps in the units had to be replaced with pumps that could be modulated over the entire speed range. This brings a reduction in energy consumption of up to 70%. Of course, new types of pumps require a higher quality of the heat transfer medium. The technical solution is to install a permanent magnetic shaft in the pump. Without the QUADROMAG magnetic filter, magnetized impurities (rust, metal fragments) circulating in the system will stick to the shaft and in 1-2 years the pump will lose its performance and seize.

In summary, these failures are caused by improper use and are not covered by the warranty, so if you need to service the pump, you will have to dig deep into your pocket.

Therefore, it is much better to think ahead and invest in a QUADROMAG magnetic filter than to lose the boiler warranty and therefore your trust in the manufacturer.

Before replacing the boiler, always have the existing system professionally cleaned with specially developed chemicals from the QUADROMAG range and protect your boiler for a trouble-free heating season!
