FAQs
What is a system boiler?
A system boiler heats your home via a storage cylinder but has the pump and expansion systems built into the boiler itself. It works on a sealed system and is ideal for homes needing hot water for multiple bathrooms.
Does this boiler come with a hot water cylinder?
No, the Vokera Synergy 20S is a system boiler and requires a separate unvented hot water cylinder to be purchased and installed.
How do I convert the boiler from NG to LPG?
The conversion should only be performed by a qualified heating engineer who has the correct conversion kit and knowledge to safely adapt the boiler's settings for LPG.
What is Opentherm compatibility?
Opentherm is a communication protocol that allows your boiler and thermostat to communicate more intelligently. This enables features like modulating boiler output based on demand, leading to better comfort and efficiency.
What is the warranty period for this boiler?
The Vokera Synergy 20S System Boiler comes with a 7-year warranty covering both parts and labor, provided it is installed and serviced annually by a qualified engineer.
How often should the boiler be serviced?
Annual servicing by a certified heating engineer is recommended to maintain optimal performance, safety, and to keep the warranty valid.
Can I install this boiler myself?
No, for safety and warranty reasons, the installation of any gas boiler, including the Vokera Synergy 20S, must be carried out by a Gas Safe registered engineer (or equivalent certified professional in your region).
Troubleshooting
Boiler not firing up
Check the thermostat setting and ensure it is calling for heat. Verify the gas supply is on and the boiler has power. Check for any error codes displayed on the digital panel and consult the manual.
No hot water or insufficient heating
Ensure the unvented cylinder is functioning correctly. Check system pressure; it should typically be between 1-2 bar when cold. Inspect for any visible leaks and ensure all valves are open.
Error code displayed
Refer to the Vokera Synergy 20S manual for a specific breakdown of error codes and their meanings. Common codes may indicate ignition failure, water pressure issues, or fan faults. Contact a qualified engineer if the issue persists.
Unusual noises from the boiler
Gurgling sounds might indicate air in the system; bleeding radiators may help. Loud banging or whistling could signal pressure issues or a component fault. An annual service should identify and resolve such issues.

Setup, Compatibility & Care
Setup: Installation of the Vokera Synergy 20S System Boiler must be performed by a certified heating engineer. The process involves connecting the boiler to the central heating pipework, the domestic hot water unvented cylinder, and the gas supply. Ensure the system is flushed thoroughly before installation. The digital touchpad allows for initial setup and configuration by the engineer.
Compatibility: This boiler is Opentherm ready, meaning it is compatible with Opentherm enabled thermostats and control systems. It is designed to work with unvented hot water cylinders. It can be converted to run on LPG or NG, so ensure the correct fuel type is specified during installation or conversion.
Care: Regular annual servicing by a qualified engineer is crucial to maintain optimal performance and warranty validity. Clean the exterior casing with a damp cloth. Avoid using abrasive cleaners. The stainless steel heat exchanger is designed for longevity but should be inspected during annual servicing. Ensure any filters within the heating system are kept clean according to the installer's recommendations.
