He has played for the football club AEK Athens for more than 10 years. He joined the club in 1994 when he was 18. He was given on loan by AEK two times, for one season to Ethnikos Piraeus and for another season to Proodeftiki FC. He has been a regular first-team player since 2001, but at the 2005–06 and 2006–07 seasons he took a back seat to newly acquired Italian keeper Stefano Sorrentino.
On 22 May 2007, Chiotis was released by AEK to join Kerkyra FC, where he signed a one-year contract which was terminated on 6 May 2008.
In June 2008, he joined APOEL and with his high-level appearances, he contributed to the winning of the Cyprus Championship 2008–09 and the qualification for the first time of the club at the group stage of the 2009–10 UEFA Champions League. In that season, his club had the lowest number of goals conceded. He was also voted as the MVP of the club for that season and became one of the favorite players of APOEL fans.
In the 2009–10 Champions League group stage he helped APOEL to take a point against Atletico Madrid in Spain by holding Atletico to zero. At the same week he was voted as the best goalkeeper of the week in the Champions League. He appeared in all six official 2009–10 UEFA Champions League group stage matches with APOEL and he had great performances.
The next season, he helped APOEL to win the 2010–11 Cypriot First Division, adding the second championship title to his honours list.
The following season, he appeared in six 2011–12 UEFA Champions League matches for APOEL, in the club's surprising run to the quarter-finals of the competition. On 7 March 2012, Chiotis helped APOEL to reach the UEFA Champions League quarter-finals by saving two penalties in the penalty shoot-out of the last 16 return match against Olympique Lyonnais.
At the end of the 2012–13 season, he became a champion for the third time in his career after winning the 2012–13 Cypriot First Division with APOEL.
During the 2013–14 season, he appeared in one 2013–14 UEFA Europa League group stage match for APOEL and managed to win all the titles in Cyprus, the Cypriot League, the Cypriot Cup and the Cypriot Super Cup.
On 25 May 2015, one day after winning the 2014–15 season double with APOEL, the team announced that Chiotis was leaving after 7 years in the club, as his contract would not be renewed. Eventually he had 121 appearances with the club in all competitions.
On 24 June 2015, aged 38, Chiotis signed a contract with Panelefsiniakos, but he left the team two months later due to important changes to the club's board of directors. A few days later, on 26 August 2015, he signed a contract with the Greek Football League side Trikala.
