This is a real energy guzzler!
The boiler makes the hot water for the kitchen sink. It is ON all the time to keep the water at 60°C. The Day DNA confirms that the boiler is ON all the time (outer circle is all green, no white segments!)
Note we use most hot water between 12h and 13h (lunch, washing dishes). The segments are darker green. Each segment represent a 15 minute period. The darker the segment, the more ON-OFF events in this 15 minute interval.

The YEAR tab of the DNA show a very high annual consumption 0f 524 kWh with a cost of 131,12 EUR! The consumption is estimated by Smappee based on the available usage data of the months May - September. The average household consumption in Belgium is 3.500 kWh, so 524 kWh is one to watch!
This appliance has both: high power ( 2.044W ) and high On time of 10 days and 16 hours on a annual basis (42 minutes and 11 seconds heating per day).
Turn this appliance off when on holidays! Watch the month of July that shows a lighter green segment in the Annual tab. I turned it off for one week! The segments of May and September are not relevant as my Smappee started to measure, half of May and this screen shot is taken half of September.
Use a Comfort Plug to turn it OFF in periods when you don't need hot water. I tested this by shutting down the boiler from 23h to 6h45 in the morning and of course it had to heat longer once turned ON again at 6h45, but the consumption per day went down by at least 15%!
