Richard George Holtby, 37, who did not give an address, was remanded in custody by Beverley magistrates.
He will appear before Hull Crown Court on August 31.
Ms Healey, 39, a divorced mother of two teenage daughters, was found dead at her home at Ellerker Hall in East Yorkshire on Monday. Holtby was arrested the same day in Scarborough.
