HEATING SYSTEM ACCESSORIES
The heating system accessories range covers everything needed for the installation, balancing and servicing of heating systems – from fittings and screw couplings through various types of valves (ball, safety, balancing, thermostatic, thermal safety) to manifolds, hydraulic separators, dirt separators and circulation pumps. You will also find electric underfloor heating and chemicals for treating the water in the system.
The range is intended for heating engineers, installation companies and skilled DIY enthusiasts who can handle replacing or adding components to a heating system.

Frequently Asked Questions
- How to choose the right valve for a heating system? It depends on the function (shutting off, balancing, protection against overpressure) and the connection diameter – we're happy to advise you when choosing.
- What is a hydraulic separator and when do I need one? It hydraulically separates the primary and secondary circuit, used mainly with boilers that have multiple heating branches or with heat pumps.
- How often should the chemicals in a heating system be changed? Corrosion inhibitor is usually topped up during any major intervention in the system or according to the boiler manufacturer's recommendation.
