Evaporative Air Coolers

[Whats on Second]

shirley the world knows they are noisy and do not work that great ?

but that dont deter TV Shopping flogging 'em

waste not your £90, and

[GranpaB]

ok.

Someone been on the sauce or got Daddy's PH account?

This is PH so unless you have a multi zone split a/c system you might as well sleep in your oven set to low because it will be cooler.

I’ve got a hose out the window portable which, with ear plugs, does a pretty decent job for the few days a year it’s needed.

I too live in aus - split system all day long over an evap.

Especially as you can heat your home in winter with a reverse cycle split - rather than all the heat escaping through the evap vents in the ceiling and out through the big box on the roof.

Evap is archaic, there are way better options nowadays.

Evap is still immensely popular, but the amount of new homes being constructed, most are with ducted A/C systems, just put solar on & you reduce your cost enormously.

Another Aus, and running ducted reverse cycle system here, which is working well on this cold rainy day with my weather station reporting 24 inside, while it is a miserable rainy 16.4 outside. It also has the humidity at 49% inside, while outside would appear to 99%.

However most people I know have the evap systems, with a couple of splits as backups for those really humid days, or a quick warm up in winter before the fires most have can start taking over. Evap systems for cooling only use about the same electricity as a light bulb, and most will have a flap that closes when they are turned off, so as not to allow the heat to escape in winter.

Depending on the installation, you won't need to open all the windows a crack, perhaps one or two to make a bit of airflow. Dead quiet too, which is why I went for a ducted over the split systems. Mate has a split in his lounge and won't run it because of the noise.

I can see that UK will be fairly humid though, so they probably will not work so well over there.

I had a portable on and it was utter crap, expensive crap.
Not really worth the costs for the week of hot weather in the UK.

Air Coolers can't evap effectively when the humdity is high. Some of them state that you should put a block of ice inside them, so you're blowing hot air over the ice to provide minimal bky localised cooling. I agree they are pants.

That’s stating the bloody obvious!I have been using them for decades, that is why you also have A/C to take over in periods of high humidity.

I'm in an old stone cottage currently with a couple of feet thick walls - lovely...

but an aircon unit would be cheaper

We have a stone cottage not far from we’re I live(Australia) went by it today, lovely looking place, I often think it would not look out of place in the Yorkshire Dales.

In the UK they sell this tat and people buy them thinking they will work, not thinkint about the humidity aspect. You see lots of these large industrial units being rented out to large shops, again making no difference!

I'm one of the few houses that has a/c (split level) although it is only installed in the main bedroom (we leave the a/c on 30 mins before anyone goes to bed and have fans pointing to Vikingette 1 & 2's room and it does a decent job of getting the whole upstairs cool.

We have multiple opening windows and can get a draft through the entire house.
I put in openers on the staircase and we did the same at our daughters house.
Its a bit naughty and would be against regulations now at the daughters as you have to stretch on the staircase turn to reach it.
Fortunately a lad we know knocked up a metal grabber that slides on and over the handle and when you squeeze the second bar of the grabber it pushes the lock in and allows you to turn the handle open - a really clever gadget that we were knocked out with

I got a split system and will never go back. If you live in a house it may only be a couple of weeks a year that it's handy, but in my flat I have the bedroom unit on from May through to September. For a lot of those months it's just dropping the temperature from a slightly uncomfortable 23/24 down to 21 (and therefore costs a neglible amount to run), but during the height of summer it is preventing the room from hitting 30+ on a regular basis.

Have used a portable in the past and it helped, but it's so loud that I couldn't sleep with it on, and once turned off, the bedroom temperature quickly started climbing again.
