How do I know when the pressure in the system becomes too low?

If the pressure drops to below 0.3 bar when the boiler is operating, the water pressure value will be displayed (flashing digit) instead of the time read-out. The system should be topped up.

What is the difference between the Comfort mode and the ECO mode?

When the domestic hot water Comfort function is enabled the heat exchanger will be kept warm to assure instant delivery of hot water. When the boiler’s ECO function is enabled it will adapt to the pattern of usage of hot tap water. As a result, the temperature of the heat exchanger will only be maintained in periods when domestic hot water was drawn on in previous days. If there is no need for rapid delivery of hot tap water, the Comfort or ECO function can be switched off.

What is double high efficiency?

Intergas uses a unique back-to-back, two-in-one aluminium heat exchanger in all our boilers. In this aluminium heat exchanger two copper circuits are integrated, one for heating and one for hot water. Because the hot water is heated directly (instead of indirectly, as is the case in all other boilers) the Intergas boiler condenses 100% of the time, in heating mode as well as in hot water mode.
