Get the guys back who fitted your cylinder. It sounds like the upstairs rads are heating by gravity up the return from the cylinder, also they may have turned the pump speed up causing your system to "pump over", or the ball valve in your expansion tank needs looked at. Either way, if it wasn't doing all this before the cylinder replacement, get them back to sort it out.
