Thanks for uploading. My boiler's screen is exactly as in the beginning of your video, that is: No hot water symbol on the bottom left corner. So the hot water does not work. If you know the reason, please tell me. Thanks.
Hi, you likely have a regular or system boiler. These types of boiler without additional Vaillant controls, are not able to adjust hot water. This can be confirmed by checking you have a hot water cylinder somewhere in the home, additionally you like have only 3 to 4 copper pipes showing below the boiler instead of what combi boilers have that is 5-6 copper pipes below.
