Daylight and what appears to be a water leak, onto the timber in photos 3 & 4. He's taken out a complete rafter, which he should not have done, and for no obvious reason. The Velux rafters, should have had the rafters sistered at either side. Insulation - what insulation?

Neither of the two is a simple nicked outer sleeve on a cable, the mechanic protection, as is under discussion here, which is more than satisfactorily repairable with a few layer of tape. Those examples given are where a screw has pierced the cable, and made metalwork live. The first case seems...

Yes, because of the war, but we aren't using much now, and for a few months. The electric is so cheap, because of the winds at the moment.

When compared to my hour, all day rate, at this moment...

Really you need someone who knows their stuff electrically, and is gas qualified, to open up the boiler - should it be needed. Many electricians will be out of their depth on heating system controls, and few will be gas qualified.

The water level in the tank, will rise and fall, as the heating warms and cools, due to expansion. If you just pour it in the tank without lowering the level, then it may take some time for it to eventually get to the rest of the system. Yes, you can scoop, or even syphon it out. Adding it at a...

The impression I got from what you said, was that the guy that came round to look, either hadn't the skill needed to diagnose, or it was simply well outside his area of expertise. Most heating engineers, would have the expertise needed to diagnose electrical issues, but by no means all. Did you...

My daytime load is around 100 to 300watts, and so a 800w panel should match it, during daylight, but would it be worth it?

Any odd-job type of person ought to be able to tackle it, or have a go at DIY. It's fine here.

You fit them, with the item you are fitting it to, full open/extended. Struts are specified by the unextended length, extended length, and their pressure Newtons.

As a mere mortal, I will continue to put my faith in inhibitor. It has kept my system free of rust, blocked pipes and radiators, for 40 years.

Did you employ someone to come out and do this, if so it's a rather strange response to suggest that they advised 'you to find out where the fault was'?

It looks to be fairly accurate, and these systems might be something I might consider investing in, once I have done the calcs - I've avoided the roof type so far, because I'm not convinced by the idea they would be worth my while, on the roof, they would be out of my direct control to maintain...

Yet another glass shattered, due to differential expansion. These are the tall, plain, cheap drinking glasses. I went through a period, of managing to break several of them. They break cleanly, down at the base, leaving a base, and a glass tube. Av has just managed to break one, in the process...

A simple slip on the keyboard, now corrected!
