Criteria for selecting fittings and connectors for heating pipes

Choosing the right elements is key. There are several important factors to consider:

Pipe material in the installation
Nominal diameter of cables
Maximum operating pressure
Heating medium temperature
Installation and operating conditions

At Onninen we always advise an individual approach to each project. Recently, we implemented a comprehensive solution for a large housing estate. We used various types of fittings and connectors. This allowed us to optimally adapt to the terrain conditions.

Many customers ask us about the durability of fittings and connectors. Our experience shows that the quality of materials is key. Elements made of high-quality brass or PE-HD serve for many years. It is also worth paying attention to the precision of workmanship. It affects the tightness of the connections.

In the case of modernization of older heating networks, we often use wall transitions. They ensure tight entry of pipes into buildings. 90° elbows are useful for bypassing terrain obstacles. Brass tees allow for flexible branching of the installation.

Practical aspects of using fittings and connectors for heating pipes

In everyday practice we see how important precision in assembly is. Even the best fittings will not fulfill their role if they are not connected properly. That is why we always recommend using the services of experienced installers. It is also worth following the manufacturers' recommendations regarding tightening torques.

Onninen recommends using compensators in longer sections of the network. They allow for controlled absorption of thermal stresses. In combination with fixed points, they ensure the stability of the entire installation. This solution works particularly well in areas with large temperature amplitudes.

Our experience shows that it is worth investing in quality. Cheaper substitutes often turn out to be more expensive in the long run. Failures and leaks generate additional costs. That is why we focus on proven solutions from renowned manufacturers.

At Onninen we offer not only products but also expert advice. Our specialists will be happy to help you choose the best solutions. We support our clients at every stage of project implementation. From concept, through material selection, to technical support during assembly.

Fittings and connectors for heating pipes are not just installation elements. This is a guarantee of safety and efficiency of heating systems. That is why their careful selection and professional installation are so important. At Onninen, we make every effort to meet these requirements.
