Hi , I've got one cold rad in front room . All the others are fine . The pipe going in rad is hot ,return pipe is cold and rad cold . I've bleed rad that didn't work so don't think there's air in it . Any ideas plz . Thanks
Is there a TRV on the rad if so remove the head and push and pull on the nipple until it moves, these often become stuck down and wont allow a flow through.
