General: VK 20 not only silences boiler noise, but also protects central heating. Its active ingredients help restore smoother function to the system. The overall result is a quieter, more efficient boiler, which helps keep energy bills and maintenance costs down.
Application: 500 ml bottle will provide effective treatment for a typical 100 litre/ten radiator system. For larger or heavily fouled systems, use further VK 20 as required. To introduce VK 20 to the system, we recommend using the the products canister to dose the system. Alternatively, dose via a radiator or the F&E tank. For long-term system protection, use VK 20 Silencer in conjunction with VK 10 Protector.
