Three more elderly people have died in the city’s scorching summer heat wave — bringing the total number of local heat-related deaths to seven, officials said yesterday.

Two Brooklyn residents — a 77-year-old woman and a 72-year-old man — succumbed to hyperthermia Aug. 1, when temperatures hit 92 degrees, authorities said.

Both had underlying illnesses, according to a spokeswoman for the city Medical Examiner’s Office.

On Thursday, an 84-year-old woman in The Bronx also passed away from the heat, which reached 85 degrees.

The three victims were in addition to four people who died in the heat July 23, when the temperature soared to a record-setting 100 degrees.

They included a 94-year-old woman, a 78-year-old woman and a 72-year-old woman, as well as a 10-year-old disabled girl.
