I've wiped one or two lead joints (although the only lead we have left now

No different from having a service contract on your heating system. Long
term, the supplier always wins. And by a large margin.

Of course the supplier wins, they are never charities - they are a
business and need to make a profit.

Back in the day, many companies were set up as a source to rent TV's
and it was a sensible option to rent one.

Dave Plowman (News) formulated on Sunday :
Probably history. In the 50s (and earlier), plumbers were often also
electricians. Steel conduit is pretty similar to working with plumbing
iron barrel. In those days, the electrical side didn't take so much
learning.

....and joiners too before then, back in the days when the job involved
cables run in wooden 'trunking'.

Me too, I used to love wiping joints and gained quite a good reputation
for the ability. By then it had become an almost obsolete skill. I last
needed to do one in this house, before it had a full refurbed back in
the early 80's.

It was never anymore sensible to rent a TV over anything else. Like say a
car. At the end of the day, you pay for the service they provide.

Other thing was the own brand sets many of the rental companies supplied
were hardly state of the art, even in the day. Famously, the lack of a

I can remember going to the Radio Show in 1963 to pick a tv for getting

was; and yes, their set had one. It was the one I bought. I'm pretty sure
it was Pye.

That’s not right. Renting avoids the high up front cost.

Yes you end up paying more, but you do get the use
of the TV when you would otherwise not have that.

Like say a car.

The difference there is that you can walk, ride a bike,
use public transport etc. With TV the only real alternative
is to stand outside a shop window and watch that TV.

At the end of the day, you pay for the service they provide.

But that’s no big deal if the alternative is no TV.

Many new kettles are of a similar design to the one that has failed, so
I thought I should buy a cheap one as it also probably can't be
repaired. I was able to get a cheap £12 one from Tesco. It has a
slightly lower power rating, 2.2Kw and a much higher minimum water
level. I wonder how well it will last

Have others had similar problems with this type of kettle?

Just had to replace my mums Morrisons cheapo kettle. Element went
open circuit.

JOOI, may I ask after how many years of service?

My experience with these 3KW jug kettles over the past decade or so
(three failed kettles so far) with their directionally agnostic circular
bases suggests they don't select a 'poorly made' element, finely crafted
to fail with a comfortable margin just out of the basic one year
warranty, to ensure repeat sales, since the cost of the precision
required to achieve an 18 +/-5 months service life, would exceed that of
an element designed simply to last the more usual 6 to 10 years
(materials cost being pretty much the same in either case).

There are plenty of other candidate components within these kettles to
choose from in order to achieve the required 'silent failure' expiry
function. The obvious primary favourite being a cheap piece of plastic,
readily replaced under warranty should they have miscalculated and land
up inundated with in-warranty repairs that exhausts their stock of
replacement spare kettles held aside to cover such outliers on the left
of the peak of their calculated failure curve.

The manufacturers also include other failure modes to guard against the
effects of clever DIY repair/prevention activities, classically that of
leaking seals rather than rely on a potentially explosive failure of the
element which is reserved as a final last ditch measure to ensure a
continuing, if belated, demand for brand new replacement kettles. I'd
expect them to be aiming for a much wider margin of 6 to 10 years service
life for the heating element in this case since this won't be the
limiting factor in the kettle's designed service life rating.

That of course, doesn't preclude the occasional premature failure
(infant mortality) so some purchasers will find themselves either
claiming on that first year warranty or else resorting to the SOGA
against the retailer.

I realise you can choose a kettle that offers a five or six year
warranty but this typically costs more than three times the price of one
with a basic one year warranty and a life expectancy of 18 to 24 months
which is why I decided to shell out the extra £2.59 for an additional two
years warranty. Other than for their unconscionably short service life,
these Cookware kettles are a perfect fit to their function... imo :)

E.g. there are ~250cc of water in a mugful. Average UK water temp is 9°C

so that to boil one cupful takes 250 x 91 calories = 2.275 kcal =
0.00264582

At a cost of say 17p a unit, the cost of boiling one mug = 0.045p per
cup approximately.

So if you make 4 cups per day the cost of making them will be £0.65p per
year. Maybe the kettle might pay for itself in 100 years, but it wont
last that long..


PS it is also possible to not fill a kettle to the brim.
