Hi All

Hope you can help

Recently started hearing a humming noise from our Double panel living room radiator when boiler and pump fire up, after about 20-30 seconds the humming fades away, it's still there but a lot more in the background. I'm assuming it is pump related but just wondered if anyone has experienced similar?

Thanks in advance

If it’s the rad, it could be the trv. I’ve had one where the customer said it was the boilers and rattling the pipes, which turned out to be a faulty brand new Try turning the trv down when it’s humming, if the noise goes away, I don’t be loooking at that.
