I spotted a swallow over the river at St Ives earlier this week, so Summer's obviously almost here.
So... I want to add a combined AC/heat-pump thing to my office. Wall-mount air-blower in the office and a heat-exchanger thingy on the outside. Something like one of these:

Daikin and Fujitsu seem pretty similar. The office itself is about 60 cubic meters, and AFAICS, one of these should manage to cool it down in Summer and warm it in winter. I guess there will be some noise, which I can live with - far better than 30+ degrees.
Any recommendations?

Most require engineers, AIUI, but this one is DIYable (it is claimed): https://www.appliancesdirect.co.uk/p/eiq-12wminv/electriq-eiq12wminv-wall-split-air-conditioner#!#specs
Although, in my case, I am useless at drilling holes in brickwork. In any case, a 3.5kW one is possibly deserving of its own contact breaker in the consumer unit?
1. Whatever you do, don't be tempted to under spec the kit. If you need enough for 60 cu m. then don't get one that's less, more is better in A/C world.
2. These things can have a large starting current spike, so make sure the lecky bits can cope. Advice from a pro lecky would be good.
3. Drilling holes in brickwork is easier than changing strings on a guitar with a Bigsby.
4. I would say most of the work you could DIY. They'll come complete with far more comprehensive instructions than IKEA.

As long as there's no requirement that they are lined up with the holes of whatever I'm trying to put on the wall, then, I agree.
The electricity requirements are relatively modest, due to the 3:1 or 4:1 efficiencies - under 10A for heating. I'll try to get some info on the in-rush currents.
