Water supply

Dirty and hard water often causes the failure of heating equipment. Therefore, to protect it from contamination with all kinds of impurities, it is necessary to install special filters in the system.

Below we will look at the design of these devices and the technology of their installation.

Purpose

Many home masters are interested in, is it really necessary to have filters for the heating system or can we do without them?

Of course, the equipment will work normally without these elements, but no one can give any guarantee of durability, as there may be water present:

  • The tiniest particles of rust;
  • Sand particles;
  • Dust containing various components;
  • Lime deposits;
  • Gaseous impurities, etc.

This part is used to ensure trouble-free operation of heating equipment and significantly increases its durability. Considering that the price of a filter is several times less than the cost of repairing a heating boiler or replacing a pump, we can say that it is really necessary. In addition, it should be borne in mind that an accident during the heating period will lead to cooling of the room.

Thus, among the advantages of using filters are the following points:

  • The device protects the system from blockages.
  • Increases the operating life of the equipment.
  • Allows less change of the coolant in the system.

Features of the device

So, filters for heating systems, as already mentioned above, clean the coolant from all sorts of impurities and contaminants.

According to their device, they are divided into three types:

Corner Mesh Are the most common type. Designed for rough cleaning, as a result of which they are also called mud traps. They are able to clean the coolant from the large and medium fractions present in the water. It should be noted that such devices are often used not only in heat-conducting, but also water supply networks.
Electronic Particles with a size of up to 0.1 μm are retained, i.e. provide the highest quality cleaning.
Coal Able to eliminate odors from the liquid.
Magnetic Are relatively new development. Their main advantage is the extraction of impurities from the water without affecting the main stream.

Externally, the filter for the heating system looks like a fitting, which is installed between the pipes when the coolant enters the system.

Note! On the case of the device there is an arrow that shows in which direction the flow of water is moving. This is necessary so as not to confuse the inlet and outlet connections.

Installation Features

It is absolutely easy to install a filter for heating with your own hands; however, in order to effectively cope with the task set before him, it is necessary to become familiar with some of the installation's nuances.

First of all, it must be said that filters for heating, like fittings, are of different diameters. Therefore, it is necessary to acquire a device of the same diameter as the pipeline at the place of its installation.

The short installation instructions are as follows:

  • Before you install this item, you need to find a suitable place that should be available for inspection and maintenance.. But, most importantly, the device is located in front of the pump. Installation in any other place will be useless.
  • Next, you need to thoroughly clean the heating system pipe from metal particles, scale, rust and other contaminants.
  • Then, the device is directly mounted. Installation is carried out in a threaded way, so adapters may be needed to connect to plastic pipes, some types of filters are connected by flange method.

Seal the threaded connection by using a fum-tape. Before and after the filter, experts recommend installing taps that allow maintenance of the device without draining water from the system.

Note! When choosing a filter, it should be remembered that it must meet the conditions of the working environment in which it will be used. Conditions include temperature, pressure, etc.

This process is complete.

Service

The heating filter clogs with time, and therefore needs periodic maintenance.

This process is extremely simple and does not take much time:

  • First you need to turn off the taps.
  • Then you need to unscrew the cover and pull out the grid.
  • Next, you need to rinse the grid and set it in place.
  • After that the cover twists, and cranes open.

Under normal conditions, this operation should be carried out at least once every six months. If the water is dirty, then the need for cleaning may appear earlier. Here, perhaps, is all the basic information you need to know about heating filters and their operation.

Conclusion

Filters, as we found out, are an indispensable element of any heating system. With their help, you can extend the life of the equipment and thereby save a lot of money, as well as avoid a number of problems.
