I also have so much interest in central heating.I know one book of 2005 on domestic central heating wiring system and control by Ray ward. And the other 2008 book on central heating is by Patrick Mitchell.

Something else that is worth mentioning is that even if they were informed that the `Heating system is full of water - Gas has been tested` etc. - it would be totally against the Gas Safety Regulations for an Electrician to wire up a Heating system which has never been operated before and then `Switch On` the Heating / Boiler to run the Heating system without it being Safely / Correctly `Commissioned` by the Heating Engineer / Registered Gas Engineer.
This is because although the Gas supply etc. to the Boiler should have already been Tested for `Gas Tightness` and available pressure at the Boiler - the Gas Engineer MUST carry out further Commissioning Tests etc. when the Boiler is fired up for the first time.
I mention this because I have known cases where exactly this HAS happened - the `Heating Engineer` has told the Electrician that the `Heating is ready to go` and has actually asked the Electrician to `Do Him a favour` and Turn On the Heating after wiring up the Controls` !
I am NOT trying to be a `Jobsworth` by posting these details / comments - rather I want Members who might be unsure of the Law regarding the Electrical Controls / Components or `Working` on a Boiler / Gas Appliance in general to be more aware of the Regulations / Legal requirements.

this is misleading, if an electrician turned on a uncommissioned appliance it would not be the electrician that has broken the gas regulations. No gas appliance can be left connected to the gas supply if uncommissioned. So if an appliance has been left connected and uncommissioned and an electrician did turn on the appliance it is the gas safe engineer that has broken a very important gas regulation. Not the electrician.
if you know of this happening as you have stated then you should report this to the hse as its dangerous and any gas safe engineer doing this should be removed from the gas safe register for being a mupet.
why do you use different colours? its alot harder to read for me.
i was pointing out that your statement was slightly misleading and could be mis-understood being on a electrical forum. An electrician turning on an appliance after he/she has wired controls will not be breaking the gas regulations so even if you personally wanted the electrician not to turn the appliance on they would be safe to do so.(unless they are removing a case which seals the combustion system).
i fully understand the "way it works" on contracts being a heating engineer myself of 20years, but i also understand that the sparks may need to operate the controls to perform his/her functional tests. There are always a need to keep the boiler running for the tenant, or circulate the cleaning chems in different situations, but a sparks turning a boiler on will never be responsilbe for its safe operation from a gas point of view (unless the case forms a combustion seal).
i would be happy for any electrican to assume any boiler i had fitted and left running to be safe to turn back on once they have done there work or any boiler i had left uncommissioned (disconnected and label'd)to be turned on to enable it to be electrically tested. I cant comment on other gas engineers bad practice's or blame any electrician for such.
