Thousands of NYCHA tenants shivered their way through the tail end of the polar vortex without heat and hot water, according to the embattled housing authority’s own stats.

Worst hit was the 14-building Castle Hill Houses in The Bronx, home to nearly 5,000 residents plagued by development-wide outages as temperatures remained in the teens overnight into Saturday.

Some residents told The Post that their apartments had been freezing for days.

“It’s been like two weeks” without heat, Myla Gotay, 41, said of the Castle Hill apartment she shares with her four kids.

“I think it’s warmer outside than it is in here,” she said Saturday afternoon, as she kept moving her single space heater from room to room.

Mom of three Rosaura Ruiz, 41, said her heat has been out for three weeks.

“My kid has been sick with asthma because of the cold,” she said of her 10-year-old daughter. “I’ve been calling NYCHA; they say they make a report … Give us heat! We’re human!”

On Thursday, Mayor de Blasio agreed to having a federal monitor oversee the troubled housing agency, which has been plagued by outages, lead paint and lax repair work.

Reps for NYCHA declined to comment on the latest outages.
