What is Vaillant comfort mode?

In a regular, or comfort mode, the pre-heat function will be on and hot water will be ready to come out of the tap on demand.

What is Burner Anticycle time?

Anti-cycling time explained This function is used only for heating mode and not hot water. It is an electronic function, which means after the timer is activated, the boiler will wait until this timer is finished, and then resume firing as normal.

What pressure should my boiler be at when it is running?

between about 1-2 bars
Normal boiler pressure should be between about 1-2 bars. The ideal boiler pressure is often marked as a range in green on the gauge itself. With red indicating the low and high boiler pressure zones. Bear in mind that your boiler may continue to work if the pressure is in these red zones.

Should you use comfort mode on boiler?

This is a useful option for ensuring that your system reaches the correct heating settings on schedule and in the most efficient way. Using an algorithm to learn how long it takes to warm up your home, Comfort Mode ensures your home reaches the set temperatures right on schedule, activating the boiler at optimal times.

What is anti cycling mode?

Anti-cycling mode is a setting in Vaillant boilers that allow you to set a time delay between the boiler switching off and firing on when there is a demand for central heating. As this is a programmable electronic function, once it is activated, the boiler will not fire up again until the set time has elapsed.

What does pump overrun mean?

Pump overrun is a normal function of a heating system. After the boiler has been switched off, the pump circulates the water to dissipate any residual heat. Some boilers don’t need pump overrun, as they are designed to handle the heat. Pump overrun should last 5-10 min, or until the water cools down enough.

What temperature should hot water be set at combi boiler?

60 degrees
To maximise efficiency, we recommend setting your radiator dial to 75 degrees and your hot water to 60 degrees. Once you’ve got your boiler running at the optimal temperature, you’ll want to set the timer for when you need heating the most.

What is the best boiler temperature setting?

As a rule, setting your heating control to 75 degrees should be sufficient to give you a perfectly warm house, while also allowing your boiler to run as economically as possible. Once this is set, you shouldn’t need to adjust it.

What is the best temperature to set your boiler?

What does the egg timer mean on Vaillant boiler?

This function is used to prevent frequent on/off operations, and therefore contributes to prolonging the life of your boiler. The symbol also appears if the boiler is in a waiting period.

Why is my Vaillant boiler not working?

There can be a number of reasons why your Vaillant boiler keeps turning off. It could be due to low water pressure, a faulty thermostat, a faulty water pump, air in the system or frozen condensate pipes. One of our engineers will be able to find the issue and quickly apply a solution for you.

Do I need pump overrun?

Most modern heat only boilers need to use pump overrun to dissipate residual heat and reduce the risk of water boiling in the heat exchanger when it is switched off.
