It is recommended to set the temperature of your boiler to between 60°C and 65°C.

How do I top up the pressure on my Vokèra combi boiler?

If the pressure on your Vokèra boiler requires ‘topping-up’, you can follow these steps:

  • Locate the filling valve connections (usually beneath the boiler)
  • Attach the filling loop to both connections
  • Open the filling valve slowly until you hear water entering the system
  • Close the filling valve when the pressure gauge (on the boiler) reads between 1 and 1.5 bar
  • Remove the filling loop from the connections
