Why can't I find a heat pump with a good SEER rating?
The USA has a law stating 13 minimum. Yet here in the
UK, I looked at Panasonic and they're all 7 to 11!

https://en.wikipedia.org/wiki/Season...ficiency_ratio

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?


Mandating a move to them on some date in the
future that I am too lazy to check because there
is no chance that that will even happen then.


I'd not heard of that. Are they banning the sale of petrol cars by a
certain year?


Yep, they actually are that stupid. Corse it aint gunna
happen because the voters will never buy that.

There are a handful of electric cars around here but not many. Probably
less than 1%.


Apparently more than half of new cars sold are
electric in Norway. The ****ers must be ****ing mad.

There are electric charging points in a few of the public car parks, but
not many.


I havent noticed any here, but havent looked for them either.
Fark, there are 20 in my town, mostly not in public carparks tho.

I see the odd charging point in people's driveways, but they're few and
far between.


Never seen one on the garage sale run here.

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.


Politics doesn't work like that even with general elections.


No reason it couldn't.


Corse there is.

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.


Yep because you never see the icing problem
with cooling and the temperature difference is
lower even here were 45C isnt at all uncommon.


So common then.


Nope, not at all uncommon isnt the same as
common. We generally get a few days over
45C, but that's nothing like it being common.

Bloody double negatives.


There is no double negative there.

I had to cancel those out to see what you meant.


Because you are brain dead.

Hang on. 45C to 20C


No one runs the house at 20C in summer.

is bigger than say 5C (your colder winters?) to 20C.


Some days don't get above 0C all day
and most winter nights get below 0C

And you lot never see 45C in summer.

Just finished reading the memoirs of a sergeant
in Napoleon's Grande Armie in the retreat from
Moscow in 1812. -20C wasn't all all uncommon
in the daytime. Unsurprisingly most froze to death.

In another memoir of a polish fella in the red army
in WW2, one red army captain got so ****ed off at
what the krauts had done that he made the prisoners
drop their pants and sit in the snow and told the
troops that those who were not dead in 30 mins
should be shot, bullet in the head,

This is the one the USA is presumably making laws about, as they use
them for AC a lot.


Yeah, its really the only viable way to do cooling
unless it's a very low humidity area where you can
use what the call swamp coolers which just have a
****ing great fan and woodwool pads with water
running over them. That's what I use myself, but
its very common to have single digit humiditys
here when you need cooling.


Aren't those liable to cause disease?


Nope, that's legionella in conventional AC cooling towers.

and where do you get the cool water from?


They have a water supply,

Aren't you constantly drawing water form the mains,


Yes, but it isnt a lot of water. Far more is
used in showers and watering the lawn.

which is short in Australia?


Only in droughts.

MUCH cheaper to run than an AC.

It's also (since it's higher) the one that the company would quote,
surely?


Normally, but that may just be a quirk of SEERs
and not seen with EERs which should quote both.


I think from the specs here (click "specifications"):
https://www.aircon.panasonic.eu/GB_e...er-silver-r32/
They're quoting SEER and EER for cooling, and SCOP and COP for heating.


Yeah, looks like it.

I'm not saying this one's any good, it's just the first one I spotted.
I'm not buying one for a few months until I've built the room it's going
into, so I haven't done much research.

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?


Not just the greenhouse effect, the sun comes
right inside the house in winter and heats the
massive great concrete slab directly as well.


That is the greenhouse effect.


Nope, greenhouses done necessarily have concrete floors.

Heat gets through the glass inwards, but fails to leave again.


But don't normally have concrete floors.

And in winter I bask in the direct sun I sit in too.


I thought all you Aussies worried about the ozone depletion bull****.


No UV gets in thru the glass patio doors.

And no we don't, and the ozone effect is in summer not winter.

Don't you ever get a few days in a row with no sun?


Not very often at all.


*******.

And I have what the manufacturers
call a heated throw which is like an electric blanket that you
have on top of you in the armchair or couch for those days.


Isn't that inconvenient?


Nope.

Unless you spend hours sat doing nothing.


Spend hours on the computer etc, nothing
like doing nothing. I prefer to read ebooks
now, so much easier to look up stuff that
you find in the book etc.

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.


But can be a big problem over time. Lots converted
their cars to dual fuel here, gas and petrol, but there
is no point in doing that anymore now that the price
of the gas has hiked so dramatically over time here.


I converted one of mine, and bought another already converted.


Two of the garage salers have them, one is dead now.

Both blew the engine.


None of ours have blown the engine. All the taxis are dual
fuel but I havent used one for years now so I'm not sure
what they mostly refuel with now. Apparently there are
only two gas refillers now. Cant say I have ever seen a
taxi refueiling so cant say what fuel they use now.

I will never use gas again, unless it was designed to use it by the
manufacturer.


The taxis mostly are. The two garage salers werent.

My current car actually has a GPL light on the dash (which I eventually
found out is the backwards way first way of the French writing LPG). So I
assume you can buy them with that option fitted.


You certainly can with our taxis. Or used to be able to anyway.

As stuff becomes scarce, cheaper alternatives are found.


Not always, sometimes its just stops being viable anymore.


Whatever, we adapt and do something else.

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


Thought you loved cooking?


Nope, I'd much prefer to never have to do it again.
I only do it to get a better result than I can buy.

Many cooks seem to prefer gas.


Yes, but not for the sort of food I prefer to eat.

Almost all the food I eat is done in a digital air
fryer now except steaks and pizzas. I don't stir
fry much at all and do all the veg in the microwave
except the stuff eaten uncooked like lettuce.

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.


Too lazy because I don't plan to buy one.


You could do it to prove a point.


Got better things to do with my time.
