HOT RADS BUT NO HOT WATER ANYMORE

[gezbates]

I HAVE A PROBLEM WITH OLD CENTRAL HEATING SYSTEM WHERE I GET HOT RADS BUT NO HOT WATER WHEN HONEYWELL PROGRAMMER IS SET ON CENTRAL HEATING AND HOT WATER AND HOT WATER.
WE USED TO HAVE BOTH HOT WATER AND RADS.
IF I PUT JUST HOT WATER ON THEN OCCASSIONALLY GET HOT WATER BUT NOT OFTEN.
IT USED TO BE FINE.
AFTER PUMP HOT WATER GOES DOWN TO CENTRAL HEATING THROUGH HONEYWELL MOTORIZED VALVE AND UP TO WATER TANK PRE MOTORIZED VALVE.

PIPE TO TOP OF TANK SEEMS TO BE HOT BUT COLD ON THE RETURN AND COLD IN TANK.

DESPERATE FOR HELP AS HAVE SMALL CHILDREN AND NO HOT WATER.
