Heaton was an unused substitute for United last season
Cardiff City have completed the signing of Manchester United goalkeeper Tom Heaton on a season-long loan deal.
"We are really pleased to be securing the services of an England under-21 keeper," said Cardiff boss Dave Jones.
Current keeper Peter Enckelman, recently released by Blackburn Rovers, has also been offered a permanent contract with the FA Cup finalists.
Chairman Peter Ridsdale has also said he will make cash available for further signings during the summer.
Heaton has played in the reserves for Manchester United, but has yet to make the first team.
A noted shot-stopper, the 22-year-old has had loan spells with Swindon and Royal Antwerp.
