What to do if HIGHPRESS ERROR appears in Thermia Boiler Supplies?
- JJohn LangAug 10, 2025
The HIGHPRESS ERROR in Thermia Boiler Supplies can occur due to several reasons: * Radiator/floor loop thermostats are insufficiently opened. * There is air in the heating system. * The strainer in the heating system is blocked. To resolve this, open the radiator/floor loop thermostats. If that doesn't work, top up and bleed the heating system. If the problem persists, it is recommended to contact your installer.
