What could you do to make an electric space heater less than 38% efficient?
Have 62% of its surface area outside the house?
Put it next to a magic German clay heater, redefine efficiency, and hope the ASA don't catch you too quickly?

Give it to a student.
apparently the EU's method is to accept electric heating is 100% efficient, then divide by a "conversion co-efficient" of 2.5 then add and remove various fiddle factors
but 100% / 2.5 gives a starting point of 40%, so saying it must achieve
38% or higher is hardly onerous, it just means it can't have more than a 2% parasitic load ...How are you judging efficiency? After all I point my light detector at a heater of the electric kind and it detects light. It may not be visible light but its probably higher in frequency than is needed to heat things. Brian
One assumes if you ran it on DC than it wood be better than AC in that case as a lot of the time on ac its running under the power it was intended for? Brian
the same way that the EU defines it for "lot 20" compliant heaters, they should just call it a rating, rather than claiming it's a percentage efficiency.
Let most of the heat escape or be released when heat isnt required and is not wanted like with the original entirely passive storage heaters when there is no one in the house because they are working during the day and the heat is gone by the time they get home after work and need heat then in a not very well insulated house.
Having just read this I quite agree its got nothing to do with efficiency as any sane engineer would define it.
Efficiency is determined by how many energy saving features are incorporated into the product;
A fixed electric local space heater will gain a 7% bonus to its rating if it comes equipped with electronic room temperature controls and a weekly programmer.
Heaters that include an open window detection feature; distance control option, such as Wi-Fi compatibility; or an adaptive start system, will then be brought over the 38% efficiency line. If they feature two or more of these features, they?ll be offering above and beyond the requirements set out by the new legislation.
No, the 38% is not applied to storage heaters
It gets less sane if you read
because the base rating turns out to be 40% (100/2.5) not 30%
So gas heating is more efficient than electric heating, but gas heating is being phased out...?

So add "features" which will either break or will cease to be supported within the next 5 years.
User then tosses the old heater into the WEEE mountain, and then buys a new one.
The gadgets on the first heater save bugger all energy/CO2 compared to an average human being with an ounce of common sense, and any savings are wiped out when the replacement is purchased.
Absolutely nothing.
You said nothing about what it applied to in your OP.
Remove the glass from the windows ?
Isn't that 'climate science' ?
A perfect example of how to use regulations and product 'features' to create planned obsolescence, waste resources, and create unnecessary employment whilst lowering everyone's living standards, except those at the top of the industrial/political empire.
Welcome to rampant greedy elitist capitalism sold as socialism and 'green'.
Remember, people calling themselves socialists *are* the people they warned you about.
I thnk it is more 'Abbottonomics'
