It sounds like you too need to learn the difference between power and energy. Energy (Wh) = Power (W) x Time (h). There really is a time component in there. :) There's everything you need to know in Wikipedia's article on the unit.

If my explanations aren't helping (entirely likely; there's a big difference between being able to understand a subject and teach it) if you Google energy power difference have a read of a few different takes on the subject which whilst all amounting to the same conclusion will use different...

it is in the equation because Energy = Power x Time. Note again though that it is a numerator i.e. it sits above the line, it is not a denominator sitting below the line of a fraction. There is no per in it like there is in mph (i.e. where speed = distance / time).

Crude, and potentially false, analogies rarely serve the purpose of helping explain a subject. You're better off sticking to the subject itself. If you must though, the unit of capacity for a battery is amp-hour (or watt-hour if you factor in voltage too thus indicating total energy capacity)...

In all fairness, the kWh unit is somewhat unusual in that we are more used to dealing with reciprocol units i.e. something per something such as miles per hour, but kWh is a multiplicative unit i.e. it is something multiplied by something. Specifically it is power multiplied by time, and is...

If a pay analogy helps, then consider the following: I want you to fix my boiler and you and two other engineers have quoted me £60 to do so. You might take it easy and do it in 3 hours, in which case you have earnt the equivalant of £20/hr. Someone else might take 2 hours, in which case they...

There's no need to agree to disagree - you just need to learn the difference between power and energy and then we'll be in agreement.

You've got that completely wrong. kWH is a composite unit of energy and thus factors in both power and time. It is a 'total value', as you put it, and is therefore directly comparable between programmes, manufacturers, energy billing etc and is therefore exactly the unit that the OP is...

Don't you just love the Internet? 15 answers, most of them for a question you didn't ask... ;) To directly answer your question, 0.26kWh is the total energy consumed for the programme.

True! (I can't help but feel I'd be a little miffed though if he announced 'it's just a pipe mate!' whilst passing me his bill.. :D)

Could be a good idea. If it's not gone soon after I've disconnected the hob maybe I'll cap it off. I am a little reluctant though as I don't want to give the impression of it being a live pipe (that's what I'd think if I found it!). I suppose bending it over to seal the pipe might be better?

He crimped the end you can see (hard to make out in the photo looking at it now) and the other end is still attached to the hob which I'll be removing soon. I don't intend on removing the redundant pipe from behind the plasterboard as it'll just result in a whole load of making good for little...

All sorted now. Thanks everyone for the input.

I too would be concerned, but then I'd be the first to admit I can be pessimistic at times. That said (or perhaps case in point!), I'd be worried that the pipe walls will have thinned at the edges of that kink and would represent a potential weak point. Looking at it another way, it would only...

Rather than pliers I'd suggest a spanner (fixed or adjustable) as pliers might end up rounding the valve off if you're not careful.

Whilst building regs do mandate minimum performance criteria for individual components, they also impose maximum limits on the amount of glazing allowed (by virtue of the fact that even the best performing glazing performs in the order of five times worse than the most basic of modern walls) and...

What do you mean by 'orangery'? It is an ill-defined ambiguous term which could mean a variety of things, often with varying levels of glazing that leads to equally varying levels of thermal performance. With the reference to open access that suggests it will be meeting building regulations in...

Incidentally, is there an equivalent of electrical 'safe zones' that apply to gas pipe routing?

Yes, it was only intended to be temporary to allow the removal of the hob, worktop and enable discovery of the branch point. On reflection though that could've taken me a week before I got round to doing everything and I can see now the unacceptable hazard this would've potentially created...

:D Thanks Ian, that's good to know. (And I can only imagine what challenges are sometimes put your way!)
