What happens if a boiler is'earthed'?
If the boiler is 'earthed', then the boiler will short to earth and blow the fuse or trip the circuit breaker. No panic, the type of electrical fault descibed is VERY unlikely anyway, so get the job done when you can.
What happens if a boiler is not electrically bonded?
If the boiler is not electrically bonded and you grab the boiler with one hand while touching other metalwork, you could make yourself the earth return path. Although the fault is unlikely, the problem is that without correct earthing and bonding, the fault can remain active for decades.
Is the boiler service pipework Earth bonded?
"It was noted that the service pipework to the boiler has not been Earth Bonded in accordance with current regulations." As it is a bank holiday weekend and I can't really start ringing round electricians - does anyone have any idea how much it would cost to get this rectified?
Can central heating be disconnected from the boiler?
As the central heating is a separate service it needs bonding. If the water and gas were dicconnected from the boiler there would still be the radiator pipes etc which would not be bonded. Cross bonding (supplementary)may be disconnected if pipe work is disconnected (for what ever reason)then the pipework to the boiler would not be earthed.

Do boiler pipes need bonding?
If you have MDPE as your supply, and copper afterwards, strictly speaking you do not need to main bond, but the NICEIC still prefer you to do so, and most sparks still will. Cross bonding under the boiler was never required in the 16th, and certainly not in the 17th.
Does central heating need bonding?
It is unlikely that a central heating system is an extraneous-conductive part and therefore it is not necessary to run a main equipotential bonding conductor to the pipework. The supplementary bonding usually carried out is usually more than sufficient.
Do water pipes need to be earthed?
As long as the Water pipe, Gas pipe or Oil pipe, coming into your property are metallic, Main Bonding is compulsory in all circumstances even when the rest of the pipes in your house are plastic.
Do you need earth bonding?
Earthing and bonding is an essential requirement of every electrical installation, however it is often overlooked by an unqualified person attempting electrical work themselves. This is just another reason to only employ a qualified 17th edition electrician or domestic installer to carry out electrical work.
Do you need to earth central heating pipes?
Yes you need the earth bonding to the Gas and Water. Just install an RCD and don't bother with the bathroom's supplementary Bonding.
Can RCD work without earth?
Without it, stray faulty voltages can go nowhere and every metal device in your house that has its metal case connected to the (non) earth, and metal pipes, etc will have 230V on it. Put the earth back and get someone who knows what they are doing*. PS The only way to test an RCD is with a proper RCD tester.
Why are gas and water pipes earthed?
It's typically needed in older buildings where gas and water pipes are made from metal rather than plastic. As they age, stray wires and plumbing can come into contact with each other and make the metallic appliances around your home electrically charged.
What is the difference between bonding and earthing?
Earthing draws the unwanted energy to the ground to protect the person who touches the metallic body of the machine during faults. Bonding ensures both the connected devices at the same level of voltage and provides a low impedance path back to the source to trip the CB in case of fault currents.
Where do you connect earth bonding?

Why are bathroom radiators earthed?
In a typical household this includes the bathroom radiator, bath, shower, basin, toilet and lighting. The earth cable prevents any unfriendly electric shocks by collecting the leaking current caused by the fault before it travels through anything metal or damp or your body!
What is difference between earthing and grounding?
Earthing VS Grounding Earthing is primarily used to avoid electric shocks. Grounding is primarily used for unbalancing when the electric system overloads. Earthing is located under the earth pit, between the equipment body and underground. It is located between the neutral of the equipment being used and the ground.
How do you check for proper earthing?
Take a light bulb holder, connected with two wires i.e., for positive and negative terminals of the bulb. Now insert one of the wires in phase and the other in neutral. The bulb glows indicating the power supply. Take out the wire from neutral and insert it into the Earth's hole.
Do radiators need earth bonding?
You don't need to bond every radiator only if they are in special locations. Normally in a domestic situation this would be in a bath or shower room or possibly in a bedroom if it has a shower cubicle. You haven't said where the rad is fitted, so you may not need to do anything.
How disruptive is installing central heating?
Replacing an entire central heating system is no easy task and is likely to cause at least some disruption to your life for a few days. Carpets may have to be lifted and surfaces could get a little messy. The installation of a new central heating system will typically take somewhere between 1 and 5 days.
How long does it take to install gas central heating?
between 1 and 5 daysIt typically takes between 1 and 5 days to install a new central heating system.

Hi, I came across an install where the equipotential bonding to the pipes feeding the boiler had been taken from the spur providing the power to it. It was run as a separate 10mm earth wire from the fuse box (connected to the earth terminal inside) and cable tied to the power flex going to the...
boiler earth bonding | PlumbersForums.net
It's supplementary bonding underneath a boiler, and no longer required if the circuits are RCD protected (17th edition) SimonJohns I think it all got a bit out of hand a few years ago when everything needed bonding and 'joining up' so that you didn't have metallic objects with different potentials.
Earth Bonding a boiler - Screwfix Community Forum
If a spark came to do an electrical inspection {EICR} there would be no comment at all to make about the absence of 'cross bonding' on the boiler becuase its not required.
earth bonding for gas - MyBuilder
hi am having electrical installation in my house and my electrician told me that the earth bonding for the gas was not done properly ( this was done when i installed the new boiler about three years ago). what they had done they have use the gas pipe as an earth bonding ! when i have spoken to the company , i was told that it was done according to the regulation at that time!

What happens if you get a short in a boiler?
If you get a short circuit in the boiler, it means the boiler can become live, and give you a electrical shock. If the boiler is 'earthed', then the boiler will short to earth and blow the fuse or trip the circuit breaker.
