Radiator nosie when hot water only on All aspects of plumbing questions and answers, help, tips and information

[zephyr06]

I recently had an issue that my radiators would warm up when i only had the hot water on. The issue was fixed ( i think a pump was changed). I've noticed in last few days that when the hot water is only on there is noise (like air) coming from the raidators (but they remain cold).

is this usual or do i need to call a plumber back out?

Thanks!

zephyr06,
Have a look at the pump and if it's on a high setting turn it down.
