Aircon insights

@Snyper564 sorry i did not read the whole thread, but just installed 3x12kBTU and want to add to a 5kW inverter. Am leaving only the geyser and stove off. They installed 3x25A breakers being one for each, but as you know thats not any indication of load. They are digital inverter windfree samsungs

Am going to check with a clamp meter when I install the inverter, but my guess is this is no problem. Its student digs so only real draw will be when they run a kettle or airfryer. I could exclude one of the three but feel that will not be necessary

I dont believe there should be an issue, to be honest go 8kw inverter you will regret going smaller my whole house, stove oven aircon etc run on an 8kw

Thank you appreciate the reply. Ordered the inverter already and may have been a bit hasty as I was concerned the recent load shedding might jack the prices up again. They are 2nd year engineer students so hopefully they can start applying some of their new found knowledge when using the system :)

Honestly they only care about Internet, lights and charging their electronics. Everything else to them is a bonus, being fridge, aircons and a quick meal. Will meter everything when I install and show them whats up.
 
So its heading into colder weather so we decided to test the heater function seems to be around 600w to keep the room a comfortable 21deg this is the same temp as we use in summer.

This thing is super efficient!

Sorry what is brights?And I've never heard of unitherm.. Is it a reputable brand?

Brights is a hardware chain.. I had also never heard of unitherm before buying two of their units for being the cheapest available at the time..

You asked for cheapest and they are the cheapest I have come across.. the two units I have are running fine so far.. one is two years old and is used almost daily, summer cooling and winter heating..

Thank you..and power wise?Do you know how much power they consume

The 12000btu inverter was running 500watts an hour when I measured, but that wasn't when the room was at temp yet.. when at temp, inverter units would ramp down, use less electricity and only ramp up again if temp increases again..

The second unit is the same, though that is a 9000btu non-inverter unit..

Wow that is energy efficient..will look into it...any idea what the non inverter consumes..is it worth paying the extra for the inverter unit

I have a inverter midea A+++ efficiency its a 9000 btu model and typically uses 1-2.5kw an entire evening during winter and 3kw a night during summer thats typically 12 hours. Inverter units are 100% the way to go will likely cover the difference in the year.

We run the heating function for the baby room to ensure its warm all night during winter

As I said, the 9000btu non-inverter consumes the same as the 12000btu inverter unit..

That should tell you all you need to know, that inverter is the way to go..

Anyone have multi-zone mini-split aircons installed? When I do my renovation in a few months I'm going to have 3 rooms with aircons, would prefer not having 3 external units too.

I think my options are:
- 1 x 3 zone mini-split (24+12+12)
- 2 X single zone (12) and 1 x dual zone (24+12)
- Ducted

I just need to find a place that sells these multi-zone units (AC direct only has Samsung ones I don't want) - any suggestions for other places to look?

A ducted system might be viable as the space isn't too huge, so the duct runs won't need to be long buut it all depends on the cost at the end. The ducted unit itself isn't too badly priced but the installation will likely be a lot more, especially when I want to add things like zone control.

I considered it, didn't get to the costing side of things because a massive sticking point for me was the single point of failure created by having a single outside unit.. if that fails you have no AC anywhere..

Yes, I have considered that. All the options have their pros and cons.

My place doesn't have such extreme temperature swings that it would unbearable to have the aircon go out for a couple of days for repair, so it's not that critical to me. I can open a window or put on the fan in a pinch.
