Heating systems
Heat should flow reliably. Every day, every winter.
TAVINOX PRESS is a stainless steel press-fit system suitable for building heating systems designed to EN 12828.
Why stainless steel for heating systems
A heating system must operate reliably for many years. Not only at start-up, but also after countless thermal cycles.
Zero oxygen diffusion
Stainless steel piping does not allow oxygen to permeate into the heating water. It protects radiators and pumps from corrosion, unlike other materials.
No chemical water treatment
The piping does not require corrosion inhibitors in the heating water, unlike carbon steel distribution systems where water treatment is mandatory.
Minimal thermal expansion
Simpler expansion compensation, fewer compensators, fewer problems when designing long pipe runs.
Clean heating circuit
No corrosion products are generated that would foul heat exchangers, valves and control fittings. The system remains hydraulically clean throughout its service life.
Service life without replacement
When operated within design conditions, stainless steel heating distribution serves for the full lifespan of the building without the need for full replacement.
Resistance to high flow rates
Essential for systems with variable flow and variable-speed pump drives.

Connection to other materials: Combination with copper and other stainless steels is unrestricted. With carbon steel only via a brass dielectric nipple (min. 50 mm), with the flow always running from carbon steel to stainless steel. The complete parameters of the TAVINOX PRESS system are given in the technical manual.

“A heating system is designed for decades. The choice of pipe material decides whether you will be dealing with repairs in 20 years — or not.”
Stainless steel press-fit piping eliminates the risk of corrosion and circuit fouling throughout the projected lifespan of the building.
