Remeha Avanta Plus
It may be necessary to bleed the central heating system or top
it up with water to ensure optimum operation of the boiler and
central heating system. If the water pressure is less than 1 bar,
the system has to be topped up with water. This section pro-
vides information on topping up, bleeding and draining.

Topping up the central heating system

Disabling the boiler
Before the central heating system can be topped up, the boiler
must be disabled. Proceed as follows:
• Open radiator valves and set the room thermostat as low
as possible.
• Switch off the boiler.
Topping up the central heating system
The Remeha Avanta Plus runs best with a water pressure of
between 1.5 and 2 bar (see the water-pressure meter at the
bottom of the boiler). If the water pressure falls below 1 bar,
the system has to be topped up with water.
 Boiler off
Ensure that the boiler is disabled.
• Wait until the temperature is below 40°C (the radiators
feel cold) before topping up.
