boiler whistle noise as it reaches temperature?
my boiler has started making a high pitch wistleing noise as it reaches temperature and just before it cuts out. the noise changes pitch if i speed up or slow down the pump. but i don’t think the noise is comming from the pump.
I’ve tried reducing the temperature of the boiler, and bleeding the rads and pump, all had no effect.
I’ve recently added some system cleaner into the system could this be causing it.
It’s a Gas fired cast aluminium heat exchanger boiler and i’ve also got a mains pressure vented hot water tank, standard Y-plan 3 port mid position valve and terrier pump.
Any ideas?
The cleaner has moved something which has moved into the heat exchanger, the whistling is the result of a partial blockage, the heatex does this when it is scaled up. Put a boiler silencer in, and keep an eye on it, this can cause some serious damage.

It sounds like there’s steam being released SOMEWHERE, and it’s causing the whistling sound, just as a teakettle does when you heat water. I’d definitely have it checked as soon as possible; until then, I’d try to keep the temperature set as low as you can, to keep pressure off the spot in question. Better to stay safe, even if it means a little cool water or bundling up a bit.
Good luck!

Check around & see if you can find any small amounts of water/condensation. Either on the floor, pipes, or anywhere around the area. that cold help you find the possible leak.
- All boilers have to have a "safey release valve". Its located ontop of the boiler (sometimes it cone shaped). It opens when there is TOO MUCH PRESSURE in the boiler. To keep the boiler from expolding. Make sure that the sound isn’t comming from there.
- It maynot be seate correctly or there maybe a problem with the operating limits o the boiler.
-if so have it checked!
