Now I imagine the logical answer is call a plumber, or heating engineer or what ever they call themselves these days.
But this being Pistonheads and everyone being an expert in everything it's worth a try..... wink
Recently my hot water tank has started buzzing, and it's quite loud, loud enough for it to be bugging me. frown
Looking at, and listerning to the tank you can't pinpoint what is making the noise it appears to be coming from inside. Everything is working fine, it's just bloody noisey. paperbag
I know if I start taking it to bits I'm likely to get wet, and it'll never work again but are these thing servicable or is it worse case time and it'll be a new tank? cry

An electrical buzz or a vibration buzz?

Difficult to tell but if I was picking one I'd say vibration, I've already cleared out anything that may have been touching the tank but the only thing near it anyway was blankets.
And no I don't have a bee. hehe

There are two things in a hot water tank, a coil that allows hot water from your heating to circulate through the water inside the tank and therefore heat it, and/or a thermostatically controlled electrical element, like a big kettle element.

I can't see why either would cuase a buzzing noise.

Make sure your immersion heater element is turned off. Does it still make the noise?

Turn off the heating, does it still make the noise?

I'm guessing it's most likely to be vibration through the heating pipes. Could you heating pump be on it's way out?

The noise dosn't appear to be directly linked to any action I do, which is bound to make it fun if I do call someone out. rolleyes
If the noise isn't being made turning the tank on, or running water makes no difference, and vice versa if the noise is there doing 'stuff' doesn't stop it. scratchchin

A bit more investigation is pointing at the pump being the issue, I'm pretty sure it's causeing the noise and it's getting worse. frown

In an ideal world changing the pump would take about 10 minutes.
Isolate water with the pump valves.
Undo the big nuts catching any water.
De-wire.
Remove.
Put new in.
Re-wire.
Open valves.
Vent.
Switch on.

It won't be that easy.....
The isolating valves rarely hold off completely. You may either have to do it with lots of towels under it OR drain down until water level is below pump. Whatever you do make sure the heating has been turned off a while to lose the heat.

One problem could be the T&P valve ( brass valve with little chrome lever) the spring inside could be worn out causing a buzzing noise, as water passes through. These valves should be tested and checked every 2 years.

It'd only have a temperature and pressure relief if it's an unvented cylinder, which it may be of course. However if it has water passing through it then there is a fault on the cylinder. An unvented cylinder (and it's valves) should be checked EVERY year.

Ah mine makes noises every now and again. Been going on for about two years. Have a new pump in reserve ready to change if need be. But always seems to be a temporary problem.

They might also like to turn the electric off before starting. Failure to do so could be shocking

Well my glacial approach to DIY brings me back to this bloody noise....it had gone away for a bit, but now it's back worse than ever. banghead
Once I got my head in the area of the racket it became clear the noise was coming from the 3 Way Diverter Valve





Of course these pics are taken with the camera pointing back at the access opening, tempted to unscrew the lid but it's a nightmare working blind and the pipes are red hot at the moment. scratchchin
