That doesn't explain why Panasonic (which are good aren't they?) are manufacturing a product which is not much better than half as good as the minimum required by US law. Is it old **** they're selling to other countries because the Americans aren't allowed to buy them?

You are right and that guy is wrong on several things. To start with
we have single phase, just like you, just a slightly different
frequency. Conventional HVAC units run on 240v. It really doesn't
matter tho if the motors are optimized for the frequency. If you buy a
mini split it doesn't matter at all. They use inverter supplies and
convert the voltage to DC as soon as it gets inside. Then it is
converted to the voltage they need for the unit.

Thought so. So why are Panasonic making such inefficient units? Are they just cheaper versions that are only available to buy outside the US? For example this is £450, and has a SEER of only 7.5, whereas your law specifies 13 minimum: https://www.aircon.panasonic.eu/GB_e...er-silver-r32/ (Scroll down and click specifications).

Doesn't it also depend on if it's been optimised for air conditioning to
cool air in the summer rather than being optimised for heating during
the winter in climates such as the UK?

Consider also it appears from many of the examples I've seen honesty

Is that necessary? If it's reversible, isn't it just that? Obviously it will be less efficient when it's pushing heat through a larger gradient (which will happen in heating mode), but that can't be helped.

Consider also it appears from many of the examples I've seen honesty
doesn't seem to be part of USA advertising.

Don't they have a government body to check they're honest?

And it ain't just the USA - almost everything you buy with a rating is a lie. Cameras with less megapixels than they say, batteries with less capacity than they say, etc. Every time I buy something like that, I test it thoroughly, then get a partial refund :-)

Sure, that was just a comment on your original
about why you see what you see with SEERs,
not saying that it isnt worth doing that way.

If my place wasn't passive solar by design
I likely would have a heat pump myself.

Not because of any ban on gas, we arent
stupid enough to do that, but because the
gas price has hiked very dramatically here.

I don't have gas connected to the house but

From Wikipedia
"In the United Kingdom, a Seasonal Energy Efficiency ratio (SEER) for
refrigeration and air conditioning products, similar to the ESEER but
with different load profile weighting factors, is used for part of the
Building Regulations Part L calculations within the Simplified
Building Energy Model (SBEM) software, and are used in the production
of Energy Performance Certificates (EPC) for new buildings within the
UK and the European Union; both as part of the European directive on
the energy performance of buildings (EPBD"

Since most of this stuff comes from China anyway I would be surprised
it is that much different if at all. This really might just be the way
they get rated in UK. I know most HVAC people say that SEER thing is
bull**** anyway as soon as they get away from the salesman..

So if he compared the EERs, he'd get a fair comparison between those
sold in the US and UK?

Does the US have a regulation on minimum EER?

That doesn't explain why Panasonic (which are good aren't they?) are
manufacturing a product which is not much better than half as good as
the
minimum required by US law. Is it old **** they're selling to other
countries because the Americans aren't allowed to buy them?

The higher SEER rating costs more and you lot don't need the
higher air conditioning capability in your summers where you
lot start whining about a heat wave when its only 25C

But they get used for heating here too,

Those by definition have a much worse SEER
when heating because the outside freezes
up in the conditions you lot have in winter.

Yes, but I'd expect the best SEER rating to be quoted if they only quote
one.

and will be a lot more as houses built after 2025 cannot have gas
boilers
by some stupid EU treehugger law.

The UK will be out of the EU by then.

But we might end up keeping the stupid law.

Yeah, could well do given you lot have
your own stupidity with electric cars.

What stupidity would that be?

Tho you stupid hairy legged cross dressing haggis
gorgers may well be back in the EU by then.

I ****ing hope not, that stupid SNP woman was told no once.

But clearly doesn't care and is demanding another.

And presumably another until she gets what she wants.

Shouldn't be allowed. The vote should have been binding for x years.

I'm already seeing new houses with heatpumps installed.

Sure, but the SEER for heating is always much worse.

But can still work out cheaper than gas.

Sure, that was just a comment on your original
about why you see what you see with SEERs,
not saying that it isnt worth doing that way.

The SEER for cooling is always higher. This is the one the USA is presumably making laws about, as they use them for AC a lot. It's also (since it's higher) the one that the company would quote, surely?

If my place wasn't passive solar by design
I likely would have a heat pump myself.

Your house is entirely heated by the greenhouse effect through windows? Don't you ever get a few days in a row with no sun?

Not because of any ban on gas, we arent
stupid enough to do that, but because the
gas price has hiked very dramatically here.

Yip, price should always be the deciding factor, it sorts things automatically. As stuff becomes scarce, cheaper alternatives are found.

I don't have gas connected to the house but
it is available down the street if I want it.

Thought you loved cooking? Many cooks seem to prefer gas.

Are you taking about heating or cooling ?

I want it for both. It's not clear from the Panasonic I was looking at
what mode the SEER applies to.

That must be spelled out on there somewhere.

It isn't.

Bet it is.

Go here and click specifications:
https://www.aircon.panasonic.eu/GB_e...er-silver-r32/

It will be somewhere else with an operation like Panasonic.

Find it then.

Ah, so SEER is calculated according to likely weather locally? Doesn't that mean if I looked at the exact same model for sale in two countries, the SEER rating would be different?

Surely all SEER are the same,

Nope, the S is for SEASONAL and that varys a lot
between those areas. That soggy little frigid island
of yours is nothing like what is seen in Texas etc.

Its not unusual to get 10 days in a row over 40C here.

all EER are the same, and all COP are the same?

Those arent SEASONAL, stupid.

It does not make sense to have SEER be different depending where you live. How then can a product have a rating? They don't know whether you're going to install it in Texas or wherever. They'd have to say "SEER (Texas) 17, SEER (Washington) 15" etc.

From Wikipedia
"In the United Kingdom, a Seasonal Energy Efficiency ratio (SEER) for

with different load profile weighting factors, is used for part of the
Building Regulations Part L calculations within the Simplified
Building Energy Model (SBEM) software, and are used in the production

ISEER is profiled in Indian weather. SEER is presumably defined on American weather (which is daft as America has vastly different climates across it). So what is sensible in the UK? I think I'd be better off comparing COP. It doesn't have any input from the seasons, so is better for directly comparing two AC units from different manufacturers.

Since most of this stuff comes from China anyway I would be surprised
it is that much different if at all. This really might just be the way
they get rated in UK. I know most HVAC people say that SEER thing is
bull**** anyway as soon as they get away from the salesman..

Like miles per gallon on cars? Some manufacturers lie more than others?

It's because we use 120/240 volt 60 Hz two-phase. Your single-phase 50
Hz is less efficient.

https://www.energystar.gov/products/...rce_heat_pumps

Doesn't it also depend on if it's been optimised for air conditioning to
cool air in the summer rather than being optimised for heating during
the winter in climates such as the UK?

Is that necessary?

For the best SEER rating, yep.

If it's reversible, isn't it just that?

Nope. The problem with using them for heating
in a climate like yours is that the outside heat
collector does ice up and you need a much
bigger outside heat absorber to get the best
SEER rating for winter heating.

You don't get that effect with summer aircons.

Obviously it will be less efficient when it's pushing heat through a
larger gradient (which will happen in heating mode), but that can't be
helped.

It can actually with two stage designs.

Consider also it appears from many of the examples I've seen honesty
doesn't seem to be part of USA advertising.

Don't they have a government body to check they're honest?

Nope.

And it ain't just the USA - almost everything you buy with a rating is a
lie.

Not a lie so much as its hard to come up with a single digit number
that really does rank the devices properly, even with something as
simple as a fridge or freezer, let alone a heat pump.

Cameras with less megapixels than they say,

That's not a rating, that's a lie about the specs.

batteries with less capacity than they say, etc.

Ditto. But that doesn't happen with the best of them like
the Panasonic Li ion batterys or the apple iphone batterys

Its more complicated with smartphone talk time which
varys quite a bit depending on whether you are in a
strong signal area or a weak one where the phone
need to transmit more power to be seen by the base.

Every time I buy something like that, I test it thoroughly, then get a
partial refund :-)

You don't with Panasonic Li ion batterys.

This website claims that SEER is always measured the same, assuming a certain temperature range:

https://asm-air.com/airconditioning/...r-what-is-eer/

"SEER can be misleading. What people often dont realize is that SEER is a ratio that only applies to a very specific set of test parameters which cover a pre-set temperature range. The problem with this is that when SEER is calculated it is calculated across the same universal range, regardless of where the person who is purchasing the air conditioner lives.

Ask yourself, when was the last time that it was 65 degrees in the summer if you live in Santa Clarita, California? Probably a lot less likely than if you live in Lake Arrowhead or worse yet, Seattle, Washington. So although SEER is a universal measure of efficiency, it can be misleading in the sense that the average temperature range in Santa Clarita is far different from the average summer temperatures in Bozeman, Montana, but yet the same SEER rating would be on the tag in each."

No, I meant the US. He says there's a minimum SEER, but I'm curious if
there's a minimum EER.

BTW, a good chance you can't find the exact same model number in the US
vs. UK, even if they were the very same, but since the cps is different,
they're probably not the very same.

OK, so suppose we have a system that's rated 13 SEER and we run it in
Santa Clarita CA and we run it in Seattle. We run an 18 SEER system
in both of those locations too. Show us where the 18 SEER system
doesn't use less energy for the amount of heat moved in both.

Bull****. A camera makes a certain number of pixels. A battery has a certain number of amp hours. For example, I bought a "Probat" (****ty make) car battery, and an Exide (good make) car battery. They were both rated at 45 Ah. I charged them both fully. Then I connected each to a car headlamp bulb, drawing about 4 amps. I measured the current over time and worked out the real Ah. The Exide was almost spot on, about 43 Ah.. The Probat was 32 Ah. I got a partial refund when I yelled at the seller. Cameras have the same problem. My Fuji camera claims 10MP. But it's very easy to determine it's actually about 2.5MP. Take a picture at full resolution in favourable lighting. Load it into Photoshop and reduce the size to 2.5MP. Save it. Load it again, then enlarge back to 10MP. Clearly this image now only has 2.5MP of data. Compare this image to the original from the camera. They're identical! So the camera was giving out no more data than a 2.5MP file. They lied.

Cameras with less megapixels than they say,

That's not a rating, that's a lie about the specs.

Rating, specs, same thing. It's a number defining the capabilities of the device.

batteries with less capacity than they say, etc.

Ditto. But that doesn't happen with the best of them like
the Panasonic Li ion batterys or the apple iphone batterys

Iphone! BUAHAHAAH!!! Everyone I know with an Iphone is constantly moaning it went flat. My £13 phone lasts for WEEKS between charges. What Apple did wrong was the same mistake Clive Sinclair made - making things smaller to the cost of everything else. No room for enough battery. My phone uses two 18650 Li Ion batteries - same as a cycle lamp - total is 4.2V 6Ah. Easy to get replacements too. Oh and you don't need special tools to open the battery cover. And the phone doesn't deliberately disable itself if an unauthorised person opens it.

Its more complicated with smartphone talk time which
varys quite a bit depending on whether you are in a
strong signal area or a weak one where the phone
need to transmit more power to be seen by the base.

Yes, a phone can't guarantee battery life, but the battery itself can state a very precise Ah. They could also simply quote the measurement along with the conditions required. Eg. this car will get 50mpg if you drive on a motorway at a constant 70mph. Or this phone will allow you to talk for 3 hours if your signal strength is 90%.

Every time I buy something like that, I test it thoroughly, then get a
partial refund :-)

You don't with Panasonic Li ion batterys.

Agreed - they don't lie. I have 6 of those 18650 Panasonics here. 3Ah on the label, 3Ah on my test. Even Samsung only get 80% of their rating.. But try Chinese **** and you get 20%!

This is the more important question.

Does the US have a regulation on minimum EER?

Presumably you mean the UK. No they don't.

No, I meant the US. He says there's a minimum SEER, but I'm curious if
there's a minimum EER.

One is proportional to the other. SEER assumes a set temperature.

BTW, a good chance you can't find the exact same model number in the US
vs. UK, even if they were the very same, but since the cps is different,
they're probably not the very same.

What is cps?
