Three Whitney Houston songs returned to the UK top 40 as more than 200,000 of the singer's singles and albums were sold following the star's death.
I Will Always Love You hit number 14 in the official singles chart on Sunday, while I Wanna Dance With Somebody went in at number 20 and One Moment In Time took the number 40 spot.
The singer – who was buried in Newark, New Jersey, on Saturday – was found submerged in the bath in her hotel room at the Beverly Hilton in Los Angeles on 11 February.
Some 200,000 of her records were bought last week, with 127,000 singles and more than 73,000 of her albums purchased online and in shops around the UK.
There were 23 individual tracks by Houston in Sunday's top 200 and 13% of tracks in the top 100 feature the late singer. Her 1992 film The Bodyguard made a re-entry on the Official Video Chart at number nine.
Official Charts Company managing director Martin Talbot said: "The tragic death of Whitney Houston came as a shock to her friends, colleagues and music fans across the world. Again, the British public is demonstrating its love of Whitney, just as it did for Amy Winehouse last year and Michael Jackson in 2009."
Houston, 48, was buried next to her father John at a brief private ceremony.
Fans and onlookers watched as her coffin was driven in a gold hearse with red and white roses placed on the roof, with family and close ones following behind in cars of the same colour.
It came after some of the biggest names in the music industry bid an emotional farewell to the singer at her funeral service at New Hope Baptist Church in Newark.
Stevie Wonder, Alicia Keys, R Kelly and a host of gospel stars performed during the ceremony, while actor Kevin Costner fought back tears as he gave a moving eulogy.
