They haven't for systems designed to be installed by qualified people, which now use R32. It is only systems where they sell to individuals that use propane (R290).

"Highly refined propane" R290.
You can top them up with boggo propane and they work just perfectly. laugh
And yes, it is causing heart attacks within the industry, because now that sweet "bend over" tax that is applied for F gases, and bend over and open particularly wide if you are a domestic customer, market - is now open to anybody.
The main garden room manufacturer near me now has their on-site boys do it after they've finished building the thing. You still need to bend over as THEY like to put it across as a specialist thing, but realistically - it isn't.

That's a good idea. Will dig my climbing gear out.

It arrived yesterday. Typically my kit of 3 core drill bits didn't have the 65mm one so bought that. Borrowed a vac pump, gauges and bought a adapter to fit the 1/4in fitting.

What adapter did you get?

It's fitted.

If it wasn't for working at height (Second floor) it would be a piece of piss to install. M



How much do pros charge for something like that? My cost was £660 all in, including a couple of tools I needed and the downpipe outside and trunking inside.

Did borrow a vacuum pump though, that would add £150ish to the job if I was buying.

£700ish for an easy install like that - and that doesn't include the A/C unit.

£1200/£1300ish I would have thought, that’d be for a non happy shopper split.

If someone wants a Mitsubishi/Daikin/Toshiba unit fitted I would be up at £1500 minimum, and people are happy to pay that...

As a customer having two Daikin units fitted today, I can confirm that you’ll be paying at least £1500 for each one.

Not sure that I’m exactly happy about that but it’s certainly the going rate.

Two installers quoted significantly more than that.

You mean how much electricity they use ? Much less then conventional electric heaters ( about 1/3 ).

Was that the only location you could fit it, as smack bang in the middle of the wall above the first and below the second floor windows doesn’t seem as if it is inconspicuous?

That's a problem with the DIY kits (though in general, they are great) - fixed refrigerant line lengths mean you can't always put them where you want to. You can buy a flaring kit and make your own lines up if you are mechanically competent though.
The instructions will tell you to add extra refrigerant to make up for the extra line length but in practice it makes very little difference unless you are siting the condensers 50m away or summat.

It's around about a kw so 17ish pence per hour.

And you get 3.5kw of cooling for that price so seems more than reasonable to me.

It will be a godsend with a heavily pregnant wife and a 1 yr old all sharing the same room this summer.

They are quite efficient to be honest.

It's a bit of an eyesore I agree but limited as we're a mid town house. I also didn't want to mess with the supplied pipes and I assumed the pre flared ends were probably better than I could do myself so that dictated the length of the hoses. You also can't drop more than 5m vertically from the indoor unit so that ruled out mounting it at ground level.

Atleast the rear facade of my house wasn't much of a looker to start with.

This one, off Amazon IIRC. Just googled which one I needed.

Ok cheers, I've got a unit in my bedroom, I got it from appliances direct a couple of years ago, it was the one that had the snap together quick connect like this.



Its worked perfectly up to now, I put a thermometer in my bedroom last night and set on 17 deg, it got it down to 16.5 from 24 in about half an hour and stayed there until I turned it off. I'm sorely tempted to get another for my living room but I don't think you can buy the quick connect anymore, I have got a vac pump and gauge set but it has the car adapters on the end so I need to convert it to home aircon sockets.

Is the gas inside just propane then? I take it that the moody gas on Ebay will top it up no problems if I extend the pipework then, I suspect the ebay gas is just propane/butane anyway. I repaired our van aircon a couple of years ago and used ebay type gas in that, whatever is in it works way better than what the factory put into it, its the coldest aircon I've ever seen now.

I almost certain any old propane would work. They recommend something like 30 grams extra refrigerant per addition 5m length of pipework.

Got mine in just in time. It's been great these last 3 nights.

It's amazing how quickly the OH can go from permanently freezing to wanting the AC set to 18 degrees.

I’ve got a 27kw 3 way split cooling the upstairs 3 bedrooms, today it’s been roasting down south, with all the internal doors open the 3 splits have cooled the entire 4 bed detached right down to the point the kids put a jumper on earlier haha.

Best thing I’ve ever fitted !!
