Hi, is something that they are happy to provide to people generally? I might be tempted myself if that’s the case

Robert, yes i think so. I just emailed them asking about the VAT removal and went from there - during our emails they offered the £50 'installation' VAT free idea.

Im collecting mine tomorrow, so will have a chat with them then if you want? and see if this is something they will do generally, will let you know what they say. I cant see they wouldnt as they were quite upfront with me and suggested it first.

Let me see what happens tomorrow and i'll report back on wednesday when im back home.

.....The wire also has got a tighter bend on it. Why would it be so much hotter. I'll try and get some photos when its running next time.

A simple calculator is: https://midsummerenergy.co.uk/voltage-drop-calculator Obviously the cable should be rated for the max current it could carry at the lowest system voltage. It should also be protected by a fuse/breaker rated to protect the cable.

If your bend was too tight, it can snap the strands inside, especially if the tight bend radius is close to a crimped lug, the outer strands can't stretch and snap, reducing the current carrying capacity, causing heat. But normally it is from poor high resistance connections. I'm now in the habit of a light scotchbright pad and MEK or IPA before torqueing connections.

So it begins.. (again).

You didn’t waste any time

Glulam backboard this time. Actively trying to do as much of it as possible with existing stock.

These wee jobs really make me appreciate the cordless tool systems. Easypeasy, no joint strain and fast!

Will let the glue cure now and go again tomorrow, good fun@

Aye, you wouldn't have had half that amount of screws if you were doing it by hand
Only got to wait till April now though..

No battery related progress here but I did get a hole cut through the gable wall for my ASHP pipework.

Right through? All the way?

Screws cheap, wood dear! DIY!

Aye, that's the floor joist you see at the back.
