The defender has signed a new contract at Alfreton Town.
Heath was impressed by what he saw - despite him missing the final stages of the National League North season.
“Josh was a great player for us and did miss the back end of the season through injury,” the Reds manager said.
“But the more minutes he had on the pitch the better he got.
“He came from full time football at Hull City to part time here, so he had to adapt to this and he produced good performances.”
“This season we want him to have a big season, he’ll be more equipped with the football and the style of plays in this league so we are looking for Josh to kick on now.”
