Vaillant valves, insulation and installation kits
This category brings together hydraulic and installation accessories for the higher output ranges of Vaillant ecoTEC plus condensing boilers, ecoCOMPACT and auroCOMPACT cascade assemblies, as well as ecoVIT floor-standing boilers. Here you will find shut-off valves with insulation for boilers up to 120 kW, safety relief valves in 4 bar and 6 bar versions, kits for replacing an older boiler version with a new one, complete connection accessories for heating and domestic hot water circuits, and the L10, L11 and L20 quick-fit installation kits with circulation pumps and hydraulic accessories ready for direct fitting into the boiler casing.
Frequently asked questions
- How do I find out which valve or kit belongs to my boiler? The decisive factors are the output range and type of boiler (for example ecoTEC plus 48–120 kW or ecoCOMPACT/auroCOMPACT) – compare the order number with the technical documentation of the boiler, or contact us.
- What is the L10/L11/L20 quick-fit installation kit? It is a hydraulic module with a circulation pump that is fitted directly into the boiler casing and serves one or more heating circuits (both direct and mixed).
- Why do some safety valves have different opening pressures? The opening pressure value (e.g. 4 or 6 bar) is selected according to the set operating pressure of the heating system and must correspond to the design documentation.
- Is it suitable to fit these accessories yourself? Work on the gas section, safety components and hydraulic circuits of the boiler may only be carried out by a qualified service technician.
