Temporary drop on pressure on baxi boiler

[Dingdangdo]

Had a baxi xclusiv fitted over two years ago and never gave it a thought until now. When I turn the central heating on or a hot water tap the pressure gauge on the boiler drops albeit temporarily before going back to normal or rises to its normal state when heating has been on etc. Is this normal?

Is this normal?

As long as you aren't needing to add water, because it drops over time, then it's fine.

Thanks for your reply. Only time it's needed topping up slightly is when I get it serviced every year.
