My boiler is oil, and 20 kW, my radiators are well under 20 kW each, I can control each area independently with the programmable TRV heads, but how efficient is a pair of 2 kW radiators likely throttled back, running on a 20 kW boiler? First the very simple, if I put an oil filled radiator in...

Main reason for ferrules was to hold the cable marking on the cable, without them the marking can fall off. I agree with @mattylad that strands can bind a screw thread, making it seem tight when it's not, normally you can feel something wrong when that happens, unless using a torque screwdriver...

I have when moving firm to firm, found some firms do set colours, like red for permeant line, blue for switched line, which leaves yellow for the com, but that was one boss and move to another firm it could change. But plumbers even use green/yellow as a line wire.

Darn good idea, not that I need them now, as lights are on voice control, I found going into any room, turning the main light on, and then lights near something we are working with be it under counter lights, up-lighters, cabinet display lights, it does not matter. But when one leaves a room and...

Sorry, no, there is no convention nationwide. I pointed out he had red to com at both switches, that was all. The red, yellow, blue are three-phase colours as are brown, black, grey, and back in the day for single phase you could get three reds and earth for strappers. But having three...

I have the same problem. A large ceiling with one power point for lights, and was considering a length of lighting track. So I can spread the light around.

My shed, wood, cost a lot more, due to the base and the power, and the lining. The same applies for brick built. Planning permission varies, if a listed building, distance from boundary, height, when I google I get results for Wales. There is a limit of courses which can be laid, within a set...

Sorry to report, it died.

I am not a heating engineer, but this looks wrong, I would have expected a seal above the open window in the panel. I found with a boiler in the garage, the seal was important, if damaged opening garage doors could blow out the pilot flame. But in my mothers house, removing the front cover...

I sat outside and watched him for nearly an hour. He does not seem injured, but better outside than in the house.

So if we get fibre, maybe time to get out the HB9CV and dust off the 2-meter set. The whole reason why I got into radio was on the Falklands no one would repair the telephone network, mainly as it went through a minefield, so good excuse, but 2-meter radios had replaced the telephone. When...

Just taken him or her outside again. They get in through the cat flap, we have a chip cat flap, but they have found a way around this, they get the cats to bring them in, so the flap opens for the cat. He is now in a garden box, with water and cheese, so he is out of sight of the cats, cheese...

The inverter is 5 kW, the panels 6 kW, it was assumed it would be rare to have maximum output from panels, so 5 kW is enough for the inverter, and that does seem correct. 39 kWh on 7th July 2026 is the best so far, I expected more near the solus, but the panels are on a south-west roof. The...

The cabinet, can both distribute and boost the signal, and often it needs power to boost the signal even when it both arrives and leaves as fibre. So my friend like myself, has batteries for his solar array, and can have part of his house on an EPS supply, so it made sense for power to the...

Yes agreed, we select a time zone in increments of an hour, so would not expect to be 15 minutes behind or in front of UTC, but in this country would expect midday or midnight to be 00:00 or 12:00 UTC not BST.

I was looking at which is the coolest room in the house. Not the actual temperature, and I had selected the flat as that was always the coolest room, so selected for beer brewing, had I not wanted to brew beer, I would not have been noting what temperature the flat was. As it stands it does not...

Halfway through the night, mid-way between dusk and dawn, what else could it mean?

Things have changed, only last night did I realise I could set tariff with zigbee. I need to do some research.

I am never alerted by lights turning on. Curtains closed, never see outside lights turn on, which happens when daughter visits, as she has access to the Google Home app. There is an annoying gate light, across the valley, which shines into my bedroom, it is a fair distance away, but still...

At the moment 16:04 UTC.
