eeprom.put and eeprom.get can be used so you don't have to worry about the size of the variable.eeprom.put also has the advantage that it first checks if the value has changed and hence does not put extra strain on the eeprom cells.
Hmm can't figure out how i can fix it i tried with put and get but still not a result it saves only the start variable that is 0°C.
