Every public housing unit in the city finally had working heat as of April 12, although three still only had partial heat, the Richmond Redevelopment and Housing Authority is reporting.

RRHA announced the news Monday as it began shutting down heating to its nearly 4,000 apartments now that spring is in full flower.

In general, the housing authority provides heat to most of its apartments between mid-October and mid-April.

The authority struggled all winter with maintaining heat in dozens of units because of problems with boilers that heat the water that circulates through radiators or with the radiators themselves.

RRHA distributed space heaters to residents to help keep temperatures in their apartments at a minimum of 68 degrees. The RRHA also employed private contractors to make repairs.

Unlike past years, RRHA sought to keep the public abreast with weekly reports on the number of apartments in which the heat did not function or was only partially working. — JEREMY M. LAZARUS
