vibrating

Oscillation is the repetitive variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. The term vibration is precisely used to describe mechanical oscillation. Familiar examples of oscillation include a swinging pendulum and alternating current.
Oscillations occur not only in mechanical systems but also in dynamic systems in virtually every area of science: for example the beating of the human heart (for circulation), business cycles in economics, predatorā€“prey population cycles in ecology, geothermal geysers in geology, vibration of strings in guitar and other string instruments, periodic firing of nerve cells in the brain, and the periodic swelling of Cepheid variable stars in astronomy.

    Hi all! I hope this is is the right place to be asking this question. I have searched all around the internet but can only find issues that are similar, none that are the same as mine. I can get specific models of everything and take pictures when I am home if that would help anyone give...

    Hammer from CH, see attached video link

    Hi got a Y plan system in a 3 storey town house and I get a " hammering" sound when the thermostat calls for heat. I've watched and you can see the pipes around the pump (Danfoss UPS2) and 3 way valve (EPH B332PF), vibrate. Further clipping has not helped, in fact made it worse. Both pump and...

    Pressure gauge vibrating like mad

    Got a Keston heat only boiler to 2 UFH manifolds off 2 2 port valves and a 2 port to the 3rd zone. Hot water off unvented but apparently the pressure gauge is going berserk. Any ideas?
