New Boiler - Gurgling Water Tank

[diy_tom]

I'm hoping someone can help me. I recently had a new worcester-bosch oil fired boiler fitted. Now, soon after the central heating comes on automatically in the morning, water circulating from the boiler
reaches the copper hot water tank in the upstairs hot press airing cupboard. There is a LOT of gurgling noises and 'sounds of water in motion' from inside the hot tank. So noisy in fact that it wakes me up. This did not happen with the old boiler.

A new water pump fitted has been fitted and I have bled the pump as well as the downstairs and upstairs radiators - no air present.
Any help would be much appreciated.

Thanks,
Tom
