My new immersion heater control shows power used today, yesterday or last 7 days, and it shows just under 4 kWh, in the past always used the oil boiler, as told oil cheaper than electric, it did not keep the water as warm as the immersion heater, but did heat more of the cylinder, so the 20 kW boile...

I would agree with the advice given, but would also add in my own house rare for all radiators to be working together, all my radiators have a TRV fitted, and most with electronic heads, the system I will admit does not work A1 with my oil fired boiler, as it does not modulate like gas boilers do. H...

The element in most domestic appliances is switched on with the line only, so even when not on, it can still cause a neutral to earth fault. With a mineral insulated heating element, the heat can move the moisture, so it can appear as if some random fault. I have in the past, when I had no test gear...

An RCD monitors the in and out current and assumes if they don't match, the current is going to earth, There is always some loss, as we use AC, so there is some inductive and capacitive linking so typically we use a 30 mA RCD. We should when installing monitor the background leakage which should not...

Living with no mains gas, I have looked into a heat pump, the first question has to be, if the power fails, how do you heat the house? As it stands, if I loose grid power, I have two ways to heat the house, one is an open fire, that is non preferred as it means burning all my BBQ supplies, and empty...

Looking at your switch, there is one supply to all three switches, with link wires, so you can use a smart switch that uses a single supply, however the smart switches I have used seem to be limited to two gang not three gang. There are two ways to get a smart switch to work without a neutral, one i...

It looks like a heat pump, however as to if it warms or cools the home or both impossible to tell. This is the problem with heat pumps, the cold bit gathers condensate, so needs a method to remove it, often just let it drip on the road below, which is a danger with legionaries. However, it could als...

The regulations refer to a tool or key, and if it needs a tool or key to change the bulb, then the person using the tool or key should isolate first, this means turn off all live feeds, which include both line and neutral, so the light switch only switches line so does not isolate. Yes I know that s...

Yes it does seem odd, we have to provide an earth to fixed equipment even if not required, the rules say "A circuit protective conductor shall be run to and terminated at each point in wiring and at each accessory except a lampholder having no exposed-conductive-parts and suspended from such a ...

Now the meter has been installed for some time, I can say the IHD (in home display) is rubbish. Last night just past midnight it showed used today £0.00 which was I suppose correct but then says of which 59.3p is standing charge so clearly an error. Also I had used 5.01 kWh which since only 3 minute...

It should be fine with a plug. British law requires items which are plugged in to be provided with a plug, so if the manufacturer says it should not be plugged in then they can sell it without a plug, so we have seen since brexit items saying they need hard wiring to get around the British law. The ...

I do get a display on the in house display which can be set to show pounds, and the solar panel software shows what I use in the day and I can go back until fitted, but same does not go for the IHD so can't view what I used yesterday in pounds, and the total kWh used does not help, as midnight until...

I have had a smart meter fitted, forced to fit one if I want paying for export, and also split tariff can reduce costs further, so totally see the point. But it came with a little monitor, we placed it on the TV stand and started to observe the readings, from sun up to sun down it alternates screens...

When I got my electronic heads, they came with a kit of adaptors, for RA, RAV, RAVL I used eQ-3 as at that time the cheapest, and latter used TP-Link (Kasa) which also included a kit.

It seems to have posted OK maybe Mr White will give it a look over, my problem is this means 4 switches need to be powered by current through the bulb, so may get a problem with bulb staying on dim, and the diagram is only my best guess, I have no way to test it.
