The Vaillant Eco Tec combination boiler is a state of the art mill designed to provide the consumer continuous warm heat and water as and if it’s necessary.
There are several distinct versions to select from based on what your requirements possibly.
A frequent issue that occurs over time with the majority of combination boilers, rather than only with Vaillant boilers is absence of warm water. It starts off with an warmth modulating going cold and hot, finally stopping altogether.
As we’re talking about the Vaillant Eco Tec Boiler I shall take you through two or three simple procedures to assess before you telephone on the regional petrol safe boiler technician.
First we must check that boiler gets enough pressure to operate to warm water. On the front of the boiler, usually at the floor right side you need to visit a pressure indicator, this ought to read around 1.2pub or just over the reddish place into the gray area.
The pressure may also be assessed from the electronic display window, then press any button on the panel, so the inner blue lighting will come on, press the button right beneath the radiator emblem, you may now find a bar symbol, press the identical button again and you’ll notice the digital strain. That can be another way to confirm the stress if you believe the gauge isn’t functioning correctly.
If the strain is right we need to move onto another test, start a hot water faucet that’s nearest to the boiler, and currently assess the boiler screen, a tap emblem must be showing. When there’s absolutely no tap emblem displaying then the ultrasonic detector maybe in fault and will have to be assessed by means of a boiler engineer.
If the logo is displaying afterward we understand that the boiler is in warm water manner and the boiler must fire up to warm the water.
Since the boiler is heating the water then you need to observe the temperature on the screen begin to rise softly, if it climbs quickly along with the boiler then melts, the temperature must fall along with the boiler will then start again.
If that is happening to a Vaillant Eco Tec subsequently the boiler is overheating and shut down to prevent some internal damage. This issue is normally because of the warm water heat exchanger becoming blocked or partially blocked with sludge.
When the above seems comfortable with your boiler, whatever make it perhaps, you’ll have to get hold of a boiler technician to replace the warm water heat exchanger, and also to flush out the system out and add inhibitor to prevent this occurring again.
Another problem that occurs with many boilers rather than simply the Vaillant Eco Tec is that the warm water only operates when the central heating system is still on. This issue is normally because of the diverter valve being trapped at the heating mode or is faulty and will have to be replaced.
All boilers whatever model or make nowadays will need to have routine maintenance, and among the critical tests that has to be performed would be to look at that system has sufficient inhibitor from the water. It is always best to top the inhibitor up whenever that the yearly service is performed. Inhibitor will protect against sludge forming inside the computer system.
Sludge is the frequent killer of warm water heat exchangers in most makes of boilers rather than simply the Vaillant Eco Tec.
All boilers if kept correctly ought to be trouble free, but sometimes things do occur. Approximately 90 percent of boiler failures are typically because of other flaws and not the boiler. They closed down to protect themselves from harm.
If you’re beginning to encounter issues with your warm water that’s heated via a combination boiler, then I’d counsel you to call somebody into confirm the boiler above, do not leave it too long as it might grow to be very costly to fix.
