The correct maintenance of radiators it is necessary to achieve thermal comfort and save energy. With maintenance of radiators we mean all those operations aimed at preserving the proper functioning of radiators and boilers.
The first thing to do for propermaintenance of radiatorsconsists in periodically checking the water pressure in the circuit and, if necessary, eliminating the air bubbles from the radiators themselves.
If the radiators don't heat upor if it is a single radiator that does not turn on or that heats up only partially, there will probably be a problem with air in the circuit and / or low pressure. In these circumstances, unscrew the vent valve located on the opposite side to the one that houses the water opening and closing key, until the air is released. If only hot water comes out of the valve, close it again and check the levels of the amount of water flowing into the system. To understand if there is enough water in the radiators, just check the pressure gauge on the boiler where you should detect a value between 1 and 1.3 bar. If you notice a lower value, open the water fill key and leave it open until you reach the ideal pressure (between 1 - 1.3 bar).

How to clean the radiators
The radiators must be dusted before each ignition and on a regular basis throughout the year. To clean the radiators, you can help yourself with flexible dust-catching duvets that are able to reach the radiator inlets. For this purpose, we recommend the microfiber duvet for dusting, versatile and washable. We advise you to use it only for cleaning radiators.
For cleaning the radiators you can use compressed air cylinders. Small compressed air cylinders of 400 - 500 ml are available on the market at a cost of 2 - 3 euros and are able to deliver a powerful blow designed to completely remove all traces of dust.
If there are children or pets in the house, it will be necessary wash the radiators with a natural degreasing product. Remember to avoid chemical detergents because they are excessively aggressive, they could damage any finishes and the surface of the radiator itself.
Avoid painting the radiators or, if you really want, use natural and breathable paints: some paints could hinder the heat output. To improve the performance of the radiators and save energy, it is advisable to install an insulating and heat-reflecting panel on the same wall that houses the radiator (the radiator is nothing more than a heat "radiator").
