A baby boy was apparently burned to death by a malfunctioning radiator in Brooklyn on Friday, cops and law-enforcement sources said.

Cops responded to an apartment on East 14th Street in Midwood shortly after 6 a.m., and found the 11-month-old child in a bedroom suffering critical burns from a heating furnace that was leaking steam, according to police and sources.

The baby was rushed to Maimonides Medical Center, where he was pronounced dead, the NYPD said.

The radiator is believed to have malfunctioned, causing a dangerous amount of steam to leak out of it, police and sources said.

Investigators were spotted examining the exterior of the building, according to a video shared by WCBS 880 reporter Marla Diamond.

In 2017, two young sisters succumbed to heinous burns when a faulty radiator turned their Bronx apartment into a “steam room,” law enforcement said at the time.

“It was probably a problem with the valve. It turned the place into a steam room,” a law-enforcement source said of the radiator issue that killed Ibanez Ambrose, 2, and her little sister, Scylee, 1.
