Gas on constantly or on and off...?

A tenant bought a desk lamp, connected the Earth wire to LIVE on the plug, and then asked me why it's not working!

That must have been many years ago. I can't remember the last time I bought an electrical device without a moulded plug ready fitted.

I blame the prevalence of the moulded plug for the majority of people now having no clue how to wire one.

Where is that actually stated please - from the link you quoted

Not sure what you're getting at. Did I post a link?

Anyway, from the IET website:
Q5: What types of electrical work are 'non-notifiable'?





The following types of work are non-notifiable:

• Replacing accessories such as socket-outlets, control switches and ceiling roses
• Replacing the cable for a single circuit only, where damaged, for example, by fire, rodent or impact (1.)
• Re-fixing or replacing the enclosures of existing installation components (2.)
• Providing mechanical protection to existing fixed installations (3.)
• Installing or upgrading main or supplementary equipotential bonding (4.)
• Work that is not in a kitchen or special location and does not involve a special installation (5.) and consists of:
  • Adding lighting points (light fittings and switches) to an existing circuit (6.)
  • Adding socket-outlets and fused spurs to an existing ring or radial circuit (6.)

Having said that, I completely rewired my house anyway and had it signed off by a NICEIC spark so I think this minor addition may get lost in the noise.

Thanks, I feel so much better now that I can't be sent to jail!!!!!

Well I can report that this unit is excellent (Honeywell CM927). Really good at getting the house up to temperature, on time, without over doing things. I'll have to see what the bills are like compared to last year but, for now, I really can recommend it, particularly if you can find an ebay special.

This subject should be a 'sticky' and simply state:

'Having heating(or hot water) timed is cheaper than having it on constantly!'

Insufficient information.

Is maintaining a temperature of say 10°C really more expensive than having the temperature rise to 25°C during the timed ON period and fall to 5°C or less during the OFF period?

There's still not enough information as the length of time it's at 25°C isn't given.

I agree it should be a sticky, there are at least two live threads asking the question.

The problem is that question(or variations) simply cannot be answered.

It is like asking is 'is it quicker to drive from London to Glasgow at a slow speed without stopping, or flat out with lots of stops'!!! To answer you need to know slow speed, fast speed, length of stops and distance.

All we can say is that with the thermostat set at the same level, e.g. 20C, it is cheaper for the heating to be on timed than on 24/7.

If the question asks is it cheaper to have it 24/7 at, say, 17C or six hours a day at 20C, then nobody can answer as it depends on several unknown factors - insulation in house, efficiency of boiler etc.

except that if you are happy living in a 17 DegC house why do you need to turn it up to 20 DegC when you introduce a timer.....

Agree absolutely.

However it is a(IMO stupid) question that is asked time and time again.

Even more stupid(there is one thread currently running) where people 'have proved' that it is cheaper to have the heating permanantly at 21C i.e. on 24/7 rather than have it on for six hours a day at 21C.

The trouble is that people actually believe nutters like that!!! There is this 'urban myth' that somehow it is cheaper to continually top up heating rather than letting the house get cold.

How can you have it on for 6 hours a day at 21 deg celcius? Your telling me that for the other 18 hours, your house only drops a degree or so? Don’t think so, and it isn’t an urban myth because I done the test both ways.

Leaving my electric fire on 24/7 set at 18 c starts off at 3kw heats up quickly maintains the temp at 1kw so approx cost intial 3kw half hour = 1.5 plus another another 23kw total 24.5kw * 10p = £2.40.

Just on from 6pm to 11pm 1.5kw +4 total 5.5kw *10p =£0.55

So £2.40 a day or £0.55 you decide.
