Heating water filters and conditioners - the key to efficient heating systems

Filters and water conditioners for heating systems are the foundation of efficient installations . At Onninen, we understand their importance perfectly. Our extensive range includes a wide selection of solutions. They ensure optimum water quality in heating systems. Selecting the right products is crucial for the durability of the installation.

In everyday practice, we observe growing interest in this category. Customers increasingly appreciate the role of water treatment. It directly affects the efficiency of heating systems. Professional filters and conditioners significantly extend the life of the installation. They also reduce the costs of operating and servicing the systems.

A variety of filters and heating water conditioners in the Onninen offer

Our offer includes a wide range of products from renowned brands. Among them are Ustm, Infracorr, Zetkama, Ferro and Flamco Meibes.   Each of these brands offers innovative solutions for water filtration and treatment . Different types of devices are available, tailored to specific needs.

  • Manual backwash filters
  • Slanted water filters
  • Filters with sedimentation tank (threaded and flanged)
  • Strainer and sediment filters
  • Compact softeners
  • Installation kits and connection fittings

We also offer the necessary accessories. These include water hardness testers and tablet salt. They are used to regenerate softeners. Connecting hoses and maintenance kits are also available. They provide comprehensive service for water treatment systems.

Criteria for selecting filters and heating water conditioners

Choosing the right solution depends on many factors . The quality of water in a given location is crucial. The size and type of the heating system are also important. At Onninen, we help you choose the optimal products. We take into account the specifics of each project.

For small home installations, we recommend compact softeners. They work great in the case of hard water. In larger systems, a combination of different devices is often used. These can be sediment filters with mesh filters. They are complemented by advanced water treatment systems.

When selecting filters, we pay attention to their capacity. Filtration accuracy is also important. For industrial systems, we recommend devices with increased durability. They must withstand difficult working conditions.

Practical applications of heating water filters and conditioners

In our daily practice we encounter a variety of application scenarios.   Heating water filters and conditioners are used in many types of facilities . They are necessary in both single-family homes and large industrial complexes.

We recently completed a project for a large shopping center. We used an advanced water filtration system there. It included sediment filters and softeners. This allowed for a significant reduction in sediments in the installation. The effect was an increase in the energy efficiency of the entire heating system.

In the case of modernization of older residential buildings, we often recommend filters with reverse flushing. They effectively remove contaminants from the installation. Thus, they improve the comfort of use and the efficiency of the heating system.

For customers in areas with particularly hard water, we recommend softening kits. They protect installations from scale build-up. They extend the life of heating devices and fittings.

At Onninen we offer comprehensive solutions for every type of installation . Our experts will be happy to advise you in selecting the right products. We invite you to contact us and take advantage of our experience in the field of filtration and treatment of heating water.
