pepperds

Hi all,

having just moved back into our house after three months out after work on an extensions, looking forward to having a lie-in back in our own bed, we were woken yesterday by what sounded like someone sitting under our floorboards with a hammer, banging erratically.

This I calculated was at the same time as the central heating coming on in the morning. I believe I've located [sort of] the area where the noise comes from, but I've a couple of questions;

- what the hell is the banging?
- can I fix it without ripping up carpet & floorboards

Someone please help us, otherwise we may think of moving back to the in-laws again.

cheers
DP

pipers

did you flush a toilet, use any other fixtures?

bleed your rads there is air in them

Didn't flush anything or do anything, this only happens when the heating comes on in the morning (and I presume will occur in the evening when we start to get colder days)

it sounds like pipe hammer
is your system sealed ?
an unsealed system can cause rapid deterioration in your rads with air and water going through the water heats up and the expansion happens and bingo a loud rattling noise.
what type of boiler do you have and how old is it?

The boiler was installed as part of the extension, so it was put in 3 months ago, and has only really started to be used this past two weeks.

The model of the boiler is a Ravenheat
