I have an ELGENA Type KB 3 boiler. At present, it is not heating the water. When first running the water tap, the water is luke-warm for a few seconds before turning cold. The switch has been in the ON position for over 30 minutes. There is a light on the boiler. The water flow rate seems normal. Power is supplied via the 240V hook-up. I would be grateful for any ideas.

I recommend that you plan for a heating time at least for an hour, rather even longer. It takes so long for the 3l to really get hot. It consumes really much energy so it is only recommended when you have external electricity.
When we don't, we heat the water we need to do the dishes with gas.

Thanks Ursel, I can confirm that the electric model is 12V - 200W. I will try a longer heating duration as you suggest. Kind Regards, Michael

If you run the boiler extended, for 2 hours at example (we often use always on, so we have no "exact" values) - you can get easily 6-7 liter hot water out of it.

Because the hot water has to get mixed and because the boiler is already hot. There is also a "3 stage" switch on the boiler itself, if I remember right. 

We have 390W Solar on the roof, so we had not to care about the power usage of the boiler.

Thanks Trippin. From an energy balance, I calculated that based on 200W electrical heating at 100 percent heating efficiency, it will take 63 seconds to raise the temperature by one degree Celsius for the 3 litre capacity. The heating duration depends on the initial and desired final temperature. On the test I undertook this morning, I left the boiler on for 1.5 hours at the highest heating setting. It didn't reach set-point but the water temperature from the tap was too hot to touch. Kind Regards, Michael
