Sound insulation, block out boiler noise?
Discussion
We have the boiler above our ensuite, which is next to our bedroom. Quite often the boiler firing in the night wakes me up. I built a crude cabinet around it, but still hear the dull rumblings & it firing up.
It is a Worcester bosch system boiler, and to be fair is pretty quiet.
In tempted to try some fire proof sound deadened panels, the triangular kind, and sticking then on the inside of the cupboard. Trying to ensure full coverage.
Having only the simplest of knowledges of sound waves though, I'm not quite sure what I should be looking for to work best for the dull rumbling noises boiler gives out? Any suggestions?
Cheers guys

We have an evohome system, which controls all the rooms individually, my young sons room is set at 16 degrees, so on cold nights the evohome will keep the boiler firing up a few times to keep the room from dropping below that 16 degree minimum.
It is a mounted on the wall, which obviously is the same wall my head is next to. I feared it might be the vibrational.
Might have to continue living with it! Thanks guys

I think you need to switch it to 'economy mode' - otherwise it fires up periodically to heat a small reservoir of water so that you get hot water from the taps more quickly.
Should be a button on the front of the boiler
System boiler, not a combi boiler. Hot water cylinder provides the hot water.Should be a button on the front of the boiler
It sounds like it is in the loft? Is it the frost stat turning the boiler on? Try one night with the heating set to off at night and see if it still fires up.
Maybe a small oil heater in your sons room overnight.

The triangular panels will do zilch for you - they are designed to absorb sound reflecting within a room and thereby making it sound less lively in the room. They don’t stop sound transmission through the surface they are mounted on, and work at higher frequencies than the dull rumble you are trying to reduce anyway.

You need mass to stop lower frequencies. A couple of layers of acoustic plasterboard with overlapping joins, sealed with decent mastic will reduce air borne sounds significantly.
Transmission sounds through walls, joists, floors and pipes are harder to deal with - these will tend to be the sounds that rumble.
Your bedroom ceiling may be acting as a soundboard also. Some extra plasterboard in the floor space between the boiler and the bedroom will help - and making sure *all* the air gaps between the rooms are filled with sealer should make a huge difference.
Depending on the construction of the house, you may want to fill around the joist ends into the wall - these are often a good conduit between rooms. It may be easier to fill these with expanding foam.
You need things to be solid and airtight. Good luck!
OP: what you probably need to cut down transmitted noise is the boiler to be on anti-vibration mounts.

I wish I'd seen these before I had mine installed in the airing cupboard.

If it's just one room, might it be easier & cheaper just to put a thermostat controlled electric radiator in that room?It is a mounted on the wall, which obviously is the same wall my head is next to. I feared it might be the vibrational.

Thanks for the suggestions guys. I am tempted to just set the room to warm up a few degrees in the middle of the night. Instead of itt turning on & off regularly, it would then just comes on, stay on for 20mins then coast until morning.

Who has their heating on all night?
I don't, but I have a house thermostat set for 15c, so on cold nights it will kick in a couple of times.Gassing Station | Homes, Gardens and DIY | Top of Page | What's New | My Stuff
