Help a widow and her five children stay warm this winter

A widow from Jerusalem with 5 children called yesterday and said her heat didn’t work, We sent her a technician immediately but he couldn’t fix the heating because it was so old. The orphans live in Jerusalem, and who does not know the Jerusalem cold that chills one to the bones ?! Additionally, they don’t have hot water because they don’t have a boiler. And of course it is not healthy for children to wash in cold water in such weather. It costs 5000 NIS to install heating. Help the orphans and the widow stay warm
