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

No I meant if its a lighting circuit with other stuff on it its probably too much

If its a lighting circuit it should be limited to 6amps at the circuit start (fusebox/CU) so you would need to check that

You dont put AC unit on a light circuit.. ever. Let your installer worry about the electrics.

I have had a quote for 4 indoor Daikin Perfera units, £8k, London suburbs. 3 units will be on external wall, one will be run through the loft, this includes electrics.

I'm going ahead, install at the end of July.

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.

Also to add, your unclear if your talking about a self install or installer one

The self install units unless they are very large send power from the indoor unit to the external as part of the cabling set (multi core "power/comms" cable, 2x refrigerant lines, water drain) so you need to power it up from inside the house not outside

Welcome to the waiting for install club.

Thanks, I would definitely use an installer who is f-gas certified?

Then as 200 says, leave it up to them to check/upgrade as necessary

Yep, I would just like to use the existing cable if possible because the CU is far away from the installation room if they recommend a new dedicated feed.

It deffo shouldn't need a dedicated feed pulling around 1kw, a fused spur from the mains is most likely

To be honest, Im not fussed with the delayed installation. It gives me a chance to clear the loft. Certainly dont want to be doing that at the moment, got to 40 plus up there at the moment.

I once had a job where the avionics test gear we made needed a 24 hour heat soak in a 55°C chamber. It was always a grab and dash moment and we always had a lookout watching through the glass panel in the chamber door to make sure we were done and out safely ASAP.

Being almost near zero humidity inside the chamber, even a minute would feel like the moisture had been sucked out of your skin.

We don't fire ours up until everything is in with the fire shut.
-50c to +80c cycles for 24 hours.
