I am looking for a reliable convert to plug a 300W 120V US fan heater into a UK socket.

The plug looks like this

http://a-bike.co.uk/wp-content/uploa...13001438_S.jpg

Maplin have a converter that does 300W for £40 but it's a bit risky as it gives no leeway.. I think the convert should support e.g. 400W or 500W..

I suppose it's a step up voltage converter that I need. According to maplin..

Maplin have a 1000W one but that is over £100, and quite big, and overkill.

I emailed rswww and they said that they don't have anything more than 45W..

I certainly don't want to get some junk from china.. I don't want some random make.

I want to get something reliable that can handle up to 400W or 500W. As there's no risk then as the heater is rated 300W. So if it goes to 380W i'll be ok.

What are my options?

Thanks

300w is almost nothing for a fan heater. Are you absolutely sure that's
correct?

What you need is a step down transformer, not a step up. Obviously, as
you have discovered, a new fan heater is far cheaper.

No, it's a step down from 240v to 120v.

Buying a UK heater is the only sensible option.

Do you really mean 300 watt, that's not much of a heater!

You want a step *down* transformer, not a step-up. You don't want
anything that talks about being an inverter.

Search for 110v transformer and you'll find loads around the £50 mark
from UK suppliers (though they're probably all originally from China).

Machine Mart probably sell them, also CPC.

It also costs about 2x more than a thermostatic 2kW UK mains fan heater!

You can always rely on Maplin for bad advice. Step down!

Maplin have a 1000W one but that is over £100, and quite big, and
overkill.

You may also find that US stuff is under engineered dependent on 60Hz
mains frequency and the motor coils may saturate on 50Hz UK mains -
which means you will get a bit more heat out until it catches fire.

A certain brand of old dreadful US brand mains electric razor (promoted
at Xmas) depends on a 60Hz mechanical resonance and is crap in the UK.

I want to get something reliable that can handle up to 400W or 500W.
As there's no risk then as the heater is rated 300W. So if it goes to
380W i'll be ok.

What are my options?

Scrap the useless 300W US toy and get a decent fan heater.
Nothing else makes sense economically or functionally.

500W autotransformer.

Or buy a new heater (cheaper)


You MIGHT just be able to use a rather large 400V AC capacitor. 32uF
might work to drop the voltage.

A boss where I worked brought a clock radio back from the US - this was
the early 1970s when they were unheard of here - and obtained an
autotransformer to drive it. How I laughed (silently) when he reported
that it lost four hours a day!

Look for a 'site transformer', often used on building sites to run 110v
tools from 240v mains. You can often pick these up for cheap in variable
cosmetic condition from local ebay/gumtree/etc - they're heavy so it's
cheaper than posting.

You'll need to make an adaptor from the US plug to the bright yellow BS4343
site connectors, or rewire the plug.

Watch for the continuous rating - often the nameplate rating is only
intended for short periods when running power tools.

If your 300W figure is correct, then I can only conclude this is some sort of specialist device which can not be replaced easily & cheaply. If the heat output is unswitched, a series capacitor (of the right values) would drop V to 120v. That can also be used if it's switched AND what's left connected can handle 240v safely.

If that doesn't apply you'll need a step down autotransformer that outputs 120v, at several times the price of the capacitor.

If your 300W figure is wrong, disregard the above.

On the heater, or on the ebay Step Down / Up Transformer 230V-110V AC UK-US Voltage Converter 200W 1000W UK?

I guess the heater plug is the one with no fuse. So will the transformer which I guess is fused, make it safe or safer?

The heater is

https://www.amazon.com/Optimus-H-411.../dp/B000GG8DTS
so is 300W

I guess it's not technically a fan, it's an infra red heater that is designed to look a bit like a fan. I don't think it has any fan on there.

Have you looked on Ebay, etc for a EU version of a infra red heater?
That would also conform to EU/UK safety regs. Something made for the US
market with its lower voltage may well not.

As an academic exercise, another factor is the fan is probably a

it will run hotter, and possibly overheat depending on its design.
To run at 50Hz, it should be run at 50/60th of its rated 60Hz
voltage, but then it will only run at approx 50/60ths of its speed
due to reduced torque and the heater will have less airflow than
designed, and possibly overheat.

I've got a big yellow building site transformer 240-110 before my immersion heater, so that it takes less power (and takes longer to heat up) and thus works from my solar panels even on dim days without taking chargeable power from the grid.

I certainly don't want to get some junk from china.. I don't want some random make.

How do you know that your heater wasn't made in China?

I want to get something reliable that can handle up to 400W or 500W. As there's no risk then as the heater is rated 300W. So if it goes to 380W i'll be ok.


Sorry, but there is one helluva risk!

The Amazon listing for that heater is confusing in the
extreme. At the top it says:

'- 300w Heating Setting'

whilst at the bottom is makes the absurd claim that:

'This device saves you up to 300 watts of energy.'

The link to the user guide doesn't help much either. No rating
is shown anywhere in the guide, nor is that any reference to
the switch for the mythical 300W mode.

This, however, makes interesting reading:

'- Avoid the use of an extension cord because the extension
cord may overheat and cause risk of fire. However, if you must
use an extension cord, the cord shall be No. 14AWG minimum
size and rated not less than 1875 watts.'!

1875W? So you need a 2kW step down transformer then, not a
300W one!

As others have said, it will be cheaper to buy a 2kW heater
with a UK plug than a hefty 2kW step-down transformer which
will also require you to change the plug on the heater.

I'm not convinced that you could do that both safely and
correctly, either.

Well no, not a fan heater at all. Its a radiant dish heater. Rather more
difficult to source outside America I imagine so if youre really
passionate about keeping it then I guess I can see why you want a
transformer.

Just dont go buying any dodgy Chinese transformers like the one mentioned

Hang on what possible use is such a small wattage heater? Are you sure its
not 3000 wat, That is what most UK fan heaters are and you can get one far
cheaper than anything to bodge an American heater to uk voltages. Also most
of the fans are synchronous motor driven and probably meant to work on 60
hz in the other country not 50hz as here so would be running slower even if
you got it to work.

I am looking for a reliable convert to plug a 300W 120V US fan heater into a
UK socket.

The plug looks like this

http://a-bike.co.uk/wp-content/uploa...13001438_S.jpg

Maplin have a converter that does 300W for £40 but it's a bit risky as it
gives no leeway.. I think the convert should support e.g. 400W or 500W.

I suppose it's a step up voltage converter that I need. According to maplin.

Maplin have a 1000W one but that is over £100, and quite big, and overkill.

I emailed rswww and they said that they don't have anything more than 45W..

I certainly don't want to get some junk from china.. I don't want some
random make.

I want to get something reliable that can handle up to 400W or 500W. As
there's no risk then as the heater is rated 300W. So if it goes to 380W i'll
be ok.

What are my options?

Thanks

[Brian Gaff]

I would suggest he gets two of the same heater and wires them in series :-)

300w is almost nothing for a fan heater. Are you absolutely sure that's
correct?

What you need is a step down transformer, not a step up. Obviously, as
you have discovered, a new fan heater is far cheaper.

[Brian Gaff]

I have no idea what that is, but simply buy two and wire them in series
then.

On the heater, or on the ebay Step Down / Up Transformer 230V-110V AC UK-US

I guess the heater plug is the one with no fuse. So will the transformer
which I guess is fused, make it safe or safer?

The heater is

I guess it's not technically a fan, it's an infra red heater that is

Buy a UK heater.
Buy a 110V tool transformer.

That does look to be the case. Assuming that it is simply an infrared
lamp with no fan motor to worry about in respect of the 50/60Hz issue,
then a basic auto transformer could be used for the job.

If you can get hold of any 200VA transformer with a split primary (120
+120 volt windings) with any random low voltage secondary windings (30v
or less for preference), you can wire the heater to the neutral end and
the tapping point formed by the other primary winding when wired in-phase
and in series for the UK's nominal 240v (Euro harmonised "230v" standard)
supply.

The heater will see half UK voltage, circa 120vac 50Hz. The frequency in
this case won't be critical unlike the case with a fan heater using an
induction motor which will not only run slower but also overheat if its
voltage isn't also reduced further by another 20v (i.e. run off a 100v
50Hz supply).

If you can find an isolating transformer (240v primary with a 120v
secondary), it's possible to double the VA rating of its fully isolated
windings mode rating by using the 120v secondary to buck the 240v supply
making it equivalent to a non isolating stepdown transformer.

If you're prepared to accept the non isolated nature of an auto-
transformer solution, you can choose a cheaper 200VA rated, 240 to 120
volt isolating transformer rather than shelling out for the more
expensive 400VA rated isolating stepdown transformer.

A 400VA isolating transformer is likely to weigh a good 16 to 20 Pounds
so the non isolating auto transformer option has a considerable benefit
regarding its weight which, in this case, will be roughly half that of
its fully isolated windings counterpart.

Or as I said, feed the while shebang via a 32uF mains rated capacitor.
That will be a cheap lossless drop to 110V allright

then why did you tell us it was a fan heater? It's a bowl heater. Use a series capacitor dropper.

By far the best, as others have said, buy a new fan heater.

As an academic exercise, another factor is the fan is probably a
shaded pole induction motor, and when run at 50Hz instead of 60Hz,
it will run hotter, and possibly overheat depending on its design.
To run at 50Hz, it should be run at 50/60th of its rated 60Hz
voltage, but then it will only run at approx 50/60ths of its speed
due to reduced torque and the heater will have less airflow than
designed, and possibly overheat.

Maybe the OP isn't aware that bowl heaters have a long history of safety problems. It's why we rarely see them now. So you already have some 'random junk' safety-wise.

300W is far more likely for a bowl heater.

Yup. And may well be worse being made for the 'land of the free' rather
than to EU regs. If there are any.

The most obvious being that the insulation on the wires and any switches
is likely only good for lower US voltage. I hope it has a tilt cutout
otherwise it will almost certainly invalidate household insurance.

Even with a tilt cutout it may still start a fire by residual heat.

Why not use an IR Bulb?

https://www.lamps2udirect.com/infra-...at-lamp/142229


Thanks,

An infra red bulb designed for 240V is great

If I don't want to make a hole in a wall and I want to get that infra red bulb powered by the mains.. What can I get?

I might look at something like that infra red bulb or even this one that is 1000 watts

https://www.lamps2udirect.com/infra-...mp-shr1k/67487

I see a strap like thing on that 1000 watt one.. I wouldn't want to hang it on something 'cos I don't want to burn the thing it hangs on..or heat the thing it hangs on too much. If I can get it on some kind of stand that can safely hold it, and raise it or move it then that'd be good. Maybe like a tripod for a bulb? Like a lamp stand basically. I suppose a lamp stand(if that's the right term?), for the 1000W bulb with the strap, would be different to one for the 300W bulb you linked to?
