When you have a system boiler, the hot water available is dependent on the size of your cylinder. If all of the hot water has been used, you’ll have to wait for more to be heated. It’s easy to stop this though - you just need to make sure that your hot water cylinder is big enough for your needs.

You should also use your boiler’s timer to make sure the cylinder is full when you need it. For example, morning showers or evening bath time. Remember that it takes up to an hour to heat a cylinder, so set it to come on a bit before you need it.
