HI THE SIMPLE ANSWER IS NO    A COMBI-BOILER SYSTEM IS A CLOSED SYSTEM USING MAINS PRESSURE, THE OLD CYLINDER AND STORAGE TANK HOT WATER SYSTEM WAS AN OPEN SYSTEM AND RELIED ON THE WATER STORAGE HEADER TANK PROVIDING THE WATER PRESSURE

YOU MAY BE ABLE TO HAVE A STORGE CYLINDER SYSTEM INSTALLED WITH NEW BOILER STORAGE TANK AND INSULATED COPPER CYLINDER BUT IT WOULD INVOLVE NEW PIPE WORK SOME WHERE FOR THE CYLINDER AND SOME WHERE FOR THE HEADER STORAGE TANK USUALLY IN THE LOFT

AS A ROUGH GUESS THE COST WOULD BE £2500  TO £3500  DEPENDS ON THE SIZE OF YOUR PROPERTY AND IF IT IS A HOUSE OR BUNGALOW ETC.

FURTHER POINT THERE ARE NOW INLINE ELECTRIC WATER HEATERS AVALIABLE WHICH MAY BE FIXED BETWEEN YOUR BOILER AND BATH TAPS  SEE SCREWFIX

MY ADVICE IS CONTACT A LOCAL HEATING ENGINEER

HOPE THIS HAS HELPED
