I was told today that every Wimpy home in the UK built in the past X

Can't speak for every area, but I know that every house on Barratt
estates in our area are fitted with Suprimas. And some other house
builders too....that's a LOT of Suprimas. Will keep you in PCBs for
ages, Geoff!

Can you say "down to a price......."?


That might hold as an argument if it were not for the fact that even at
trade prices the Suprimas are not that good a choice.

Apart from the very low powered units if you take a middling 60 kBtu/hr
(c. 18kW)
unit with the flue and the VAT you are talking about the same money as a
system boiler from Vaillant. The latter has the pump, filling loop and all
the sealed system components included. (That alone would be pushing £100 +
fitting labour).

I've never seen this. All the ones I've had dealings with had series
heaters with a series resistor. Some radios used special mains cord as the
resistor.

Rule of thumb, AC current flow, 80mA/uF. Use large oiled paper/foil
capacitors if you want trouble free operation.

Surely the cost of the returns in dealing with them would start to
compare with the cost of a better design.......

Andy you're on dangerous ground here, applying logic and such

Well.... they applied a brain at least, albeit not a heart.

I've always had the view that if the running of business is dominated
by one discipline (e.g. accountants, marketeers, engineers, sales) to
the point where the others have little influence, then it will
probably ultimately fail.

When accountants get a stranglehold of a company, you know it's about to
stagnate

As for marketing, what does everyone else feel about RS's new "vision"
statement - "Do great things" ...

"I want to buy some capacitors, I promise I'll do great things with
them, ... honest"

In these situations it's best to marvel at the wonders of paid
employment, but it's not easy to do as a graduate!

But they're still in business so it shows how bad things can get
without being terminal.

What was the application? It sounds like it was designed for
retrofitting if there was no provision for a separate mains feed to
the circuit. Not easy to power a circuit from both sides of a relay
alone.


The controls were electronic equivalents of a standard bimetallic
thermostat so they had to be retrofittable to an existing circuit and
would not confuse a plumber who was not an electrician.

Hmmm, begs the question, why have an electronic equivalent of a
standard thermostat, or was there something else to it.

It was the cachet of having "Electronic" controls. It supposedly
implied accuracy and up to datedness in an era when most easily
affordable controls were electromechanical. The controls were designed
to be as accurate as the most accurate electromechanical control and
no more expensive than the average electromechanical equivalent.
Unfortunately this meant quality/size compromises in the components
selected and the standard of assembly.

Ooops, the UK has a history of invention but isn't very good at
innovation. A quality culture like the Japs (and to some extent the
Germans) have is needed to get it right, plus consumers ready to pay a
bit more for something better.

cheers,

Sorry it's an expression from Ye Shedde. A cloff is what you use to
clean whatever you've just sprayed over the screen/keyboard.

The English invent it.

The Germans develop it

The Japanese make it well Chinese nowadays perhaps

The Americans buy it

And the French resent the English for having the idea in the first
place!....
