Split Air con

I've been tempted to get another unit for our bedroom and power it with our solar but it's not always that hot in our master bedroom apart from a few nights a year (few nights inbound!), but it's been a god send in my office bedroom which is south facing as I can have it on all day cooling the room whilst I work.

Is it possible to add extra room units to an existing install later on or would that require an extra external unit?

e.g. if I got the 2x bedrooms done and then added the living room 6 months later - Do I need an extra outside unit (whatever they are called) or can I add it to the existing unit, assuming that it is specced to run 3x units in the first place of course.

As long as you buy an external unit that supports enough in door connections then you can add internal units later
 
well that was a nice surprise, cheaper than I was expecting :confused:

2 x daikin units, fitted inc electrics £3,600

he's put down 2kw units, I think 2.5kw and might upgrade the indoors to the next model up so might be a bit more yet
 
It says:

1 x 2MXM40A9
2 x FTXM20A

He says 2kw is perfect for our rooms (3.2mx4.2m) and anything higher would need a lot of electrical work

Still tempted just to bite the bullet

Have you had other quotes for comparison? It feels a little pricey but I'm not an expert. My quote is £6400 for 1 x 10kW outdoor unit and 4x indoors units (2kw, 2kw, 5kw, 3.5kw) including electrics.


This might be useful.

Daikin 2MXM40A9 Twin Split Outdoor Unit

This Daikin 2MXM40A9 twin split outdoor unit is fitted with either the 2.0kw or 2.5kw indoor wall mounted units

TBH, 2 kW is probably fine unless you have massive windows or poor/no insulation. However, you can run 2x 2.5 kW on the same outdoor unit anyway, so electrics wouldn't change. The only difference between the Daikin unit capacity is the maximum fan speed anyway, the heat exchanger in the FCUs is the same size (and refrigerant priority changes if you mix multiple capacities, but that doesn't apply if they're all the same)

My advice is don’t oversize. You’ll be running these on their lowest modulating setting 90% of the time.

This!

Don't make the mistake of oversizing your heatpump, they don't like it, if it's too powerful for the space you are cooling it will reach its thermostat temp target too fast and then shut off and it will keep turning itself on and off through the day which is not efficient, causes additional wear and tear and doesn't give enough time for the system to effectively reduce humidity in your house

Had a quote for:
ASEH09KMCG x 3 Fujitsu 2.5kw units
AOEG24KBCA3

Due to all my bedrooms having hipped roofs on external walls. He’s gonna up into the loft and drop down and going to use condensate pumps on all 3, which bumps the cost up a fair bit.

Quote is £6900

Still it’s a bit more than I thought it’d be but I’m gonna go ahead. Fed up of this heat and it’s not just me it’s the kids. Putting them to bed in rooms 28C+. Then sneaking in their rooms when the suns gone down to crack the windows and open their blinds/curtains. But then they wake up at 4am when the sunrises… double whammy of struggling to sleep and little ones waking at the crack of dawn. Can’t do it with a 2 year old and 8 month old.

A/c will let us keep their blinds shut all night and they’ll sleep til 7am again.
 
Hello, does anyone know how much power a fixed split AC uses (say just one unit)?

I have external power running along one side of the house to a fish pond, this is no high output cooker feed, probably just a ring for lights.

This would probably make for an easy installation, in theory I could use this power source and only need to drill one hole in the wall and fit everything with the minimum work.

But I am just worried about overloading the cabling.

I've seen LG units with their eco settings where you can reduce cooling/power draw.

Thanks
 
More than a lighting spur would be safe on really
In exact terms its how long is a piece of string but a heat pump type split unit unless its a monster will be using something like 1000w at max

The self fit 12000 unit I bought is 870w to generate approx 4x that as cooling (3.65kw)

Thanks, to be clear you think its OK and I won't overload the existing cabling?
