Thanks for that. I'll guess I'll have to look into the UPS route in more detail. (y)

Thanks but I'm not sure that is correct as I have seen many panel on flat roofs that have been angled. I believe if you involve planning and get permission then you can alter the angle. Not 100% sure but guess I will find out during my investigations....

Thanks, I was not aware of that but I need to discuss with planning anyway as my build has had the permitted development rights removed and I only have permission for 2 of the 3 roofs at the moment. Thanks, I I've had a quick look at the calculator and it does look like it may do the trick. I...

It does have various sizes noted on it, including 14mm and 16mm so one of those may work.

Thanks, that's what I'm planning to do, have a system that will disconnect the vital circuits from the mains and use the battery in times of a power cut. Not sure how this would work if an individual circuit tripped out though?

Thanks for that, I think I will give it a go! (y)

Thanks for the reply. (y) I'm going to have a solar PV with batteries so the alarm and network should both have back up via that. Plus I should be able have an alert to my phone if either lose mains power (i think!):unsure:

Hi all, I am designing a Solar PV / Battery / Export system and I will have panels on 3 different roofs, E, W and N, S not possible. I have trawled the net and found a couple of calculators and articles about efficiencies and angles etc but non take into consideration all aspects. This is what...

Hi all, Hoping for some help. Should I put my alarm panel on its own power circuit? Should I put my Ethernet hub on its own power circuit? Regards, Mark.

Would the heating and quenching make the copper weaker and therefore unsuitable for domestic plumbing?

Thanks but what type of pipe? I tried on 15mm copper and it did not seem strong enough to bend it.

Hi all, Can anyone tell me what type of pipe this is for? I tried bending some 15mm copper pipe with no success but I could be using it incorrectly. :unsure: Thanks. Mark.

@RandomGrinch Thanks for that info. I guess I'll probably just go down the coupler route then. (y)

Thanks and I suppose I could use a coupler but ideally I want to be able to make a lead where one end is a male and the other a female. So basically female rj45 plugs.

Hi all again, More help required please... So I have the male ended sorted but can anyone tell me what RJ45 female connector I need if I want make one end of a cable female? And will I need any special tools? Regards, Mark.

Hi all and thanks for your help. (y) I'll prob just buy the full set and then just swap the head bit then at least I don.t have to mess about with any plumbing :)

I have decided that I will remove the debris from the outside by removing / lifting tiles as @kp00110 suggested. However I'm gonna wait until the weathers a bit warmer and the roof is not covered in frost! Thanks to all for you help.

Thanks all for your help. (y) I have purchased a ratchet crimper, 100 shielded cat6 pass through plugs and 100 boots of mixed colours. All have arrived and seem to appear decent quality. Next step is to try and see if I can knock up a patch lead before I start to mess about with the network...

Hi all, One of my TRV heads has broken and I only want to replace the head and not the valve. After a quick google I think I will need to use the exact same head to ensure the calibration is correct. It is a Boss with no part number on it and it is quite old so I am hoping that someone can...

In the middle about 2/3 of the way down the pic it shows the felt being stretched by the debris which is jammed between the underside of the tile and the felt. I suppose that could be an option. May be a bit difficult to find the right tile to lift.
