A leak or badly set-up Rads may be stealing heat from cylinder. Get installer back to sort it?

When you turn off the boiler can you see if the circulating pump turns off too..

If you think you may have a leak, turn off the cold feed to the cylinder overnight and see if you've hot water in the cylinder in the morning
