We are contemplating buying a new cooker (one of those electric ones with
the hobs that heat up immediately and wipe clean).

However... we have an old gas one now, and no wiring facility for a cooker
in the kitchen.

We do have a combi boiler there, which I assume is not on the ring main.

Might the cabling for the combi take enough current to enable a cooker box
to be 'spurred' from it's own wire that runs to the fuse box?. The box is at
the other end of the house, and therefore the electric cooker is rather a
non-starter if this can't be done.

NB I don't intend to try wiring any of this myself.

Thanks,

Keith

No.
Not even close.

The combi boiler's primary energy source will be gas.
The electrical supply to it is tiny, only designed for the control system.

There's no way the electrical supply to a combi boiler is up to feeding an
all-electric cooker.
That will require a dedicated supply run from your Consumer Unit.

Why not install a nice electric fan oven and a decent gas hob?

Poor assumption, there is a fair chance it is.

Absolutely no chance!

Some ovens are designed to run from an ordinary socket circuit. However
hobs will frequently require a supply capable of providing 6kW or more
(contrast this to the 500W your combi requires).

NB I don't intend to try wiring any of this myself.

In which case why worry? Let the sparks work out how to get the new
cable there.

Is it buggery ...

They are normally fused at 3A

However, electric cookers are capable of taking a significant current
and normally are on their own dedicated (30A ?) circuit

Me thinks you're being disingenuous. The guy obviously meant comparatively and
he's right.

Be wary of such claims.

Since the electricity supply for gas heating system is tiny it could well
be via a spur.

*Absolutely* not. An electric cooker is one of the few things in a house
that needs its own high current radial supply. It's possible there is a
suitable supply already run in though but currently unused. An easy way to
check might be to look for unused 30 or 45 amp circuits in the CU.

NB I don't intend to try wiring any of this myself.

Probably just as well. ;-)

Huh?
That's exactly what I said.
The combi 3A supply is 'tiny' in comparison to the required circuit, and
totally inadequate.

Did you interpret my post differently?

I would associate "tiny" with something like a bell push transformer

I would not call several hundred watts "tiny"

I think it's an appropriate word in the current context of an electric
cooker supply.

But a boiler doesn't use several hundred watts. More like under a 100 even
with the pump running - although it will perhaps have occasional peak
demands higher than that when a solenoid etc operates.

There is a way it could be done all electric, but not the way you
want. There's no way you can run an all in one elec cooker without a
big fat supply wire going in. Not unles its a mini one anyway,

A factor of 10 ?

If that's what you want to think, that's your prerogative

I don't

Yes it does

the fan alone uses 50 watts +/- a bit
the pump what, 80 ?
add a further 20 watts for everything else...
