Do you have a thermostat on your cylinder, and if so is it turned right down?

Otherwise it could be a zone valve or an air lock.

Did you mention the problem you were having to the heating engineer who changed your tank 6 months ago? If so call him back and tell him it is no better.

or find a reliable qualified heating engineer in your area on our Find a Tradesman section https://www.diydoctor.org.uk/find-tradesmen/
