There must be 101 ways of controlling energy use in the home. Including the occupants deciding when to use items. My domestic hot water is heated by electric only when the CT coil on the meter tails detects I am exporting power. Since 00:30 to 05:30 my electric costs less, I do use the washing...

Around 150, I assume, meters above sea level. Sheltered, on the side of a hill, mid-Wales.

Working is not the same as working efficiently. I know I don't need all rooms to be heated at the same time, many homes have two zones, mine has programmable TRV heads as well, so I can select when rooms are heated, the largest room has two double panel radiators, so can likely sink around 3...

I would like to remove all the leaves in the pond, but near impossible as tadpoles still swimming around the pond. I like frogs, they get rid of flies, so don't want to kill any tadpoles.

There are covers to take wallmart plugs not sure I like the idea, as can't disconnect in a hurry.

The old ding-dong doorbell used a coil of wire which will need more AC voltage to DC voltage, and typically needed either 3 volt DC or 8 volts AC. And the current used was often greater than the transformer rating, and we rely on the caller not pushing the button for too long, but unless they...

I have LED strips, and also have a problem to hide the units, turning the low voltage to extra low voltage. But without pictures, it is hard to comment on what you are trying to do. Note, 50 volt AC is the line between extra low voltage and low voltage, so 24 volt is extra low voltage, and 230...

Well done. I have Wiser fitted, would be interesting to see how they compare.

Assuming like for like, I note Hive does have OpenTherm I am assuming you're not using that option, and also you are fitting a single channel version of Hive.

I was looking at the notice for road works, which stated there would be a 30 MPH speed limit around the road works, but they are in a 20 MPH area. To be frank 10 MPH would be more appropriate, but it does raise questions as to the legal status of both 20 and 30 MPH speed limits, with repeater...

That is also very true, I had to call the solar installers back to move what they had installed.

They do as a deal, Octopus Go has at least three different off-peak tariffs, with no giving of control to Octopus 8.5p/kWh, giving them control of when vehicle is charged 7p/kWh, with the car and charging station installed by them 6p/kWh. Yes you can change supplier, and tariffs, but some...

Sorry yes, I forget living in Wales, so easy to forget the English rules, Oh to drive at 30 in a built-up area.

There are two amp ratings on the RCD, one is its running amps, and the other short circuit amps. So if the loop impedance is 0.25Ω then 230/0.25 = 920 amps, so a RCD rated 6kA is OK, as it will handle that current without bursting into flames, for the short time it takes for the protection...

You simply ask the DNO, and they are duty bound to tell you.

I had a 3.5 kW Myson fan assisted radiator in the last house, and it did work well, and was compact. But this was before the condensate boiler. There are two ways to control the output of a radiator, one is water flow, the other is fan speed, they both will in turn control the boiler output due...

Either the supply, or the total of distribution, should be below or equal to RCD size. I am not saying I agree with that, in my home I can look at the power used, and I know nowhere near the 60 amp limit of the fuse, not that it matters as all RCBO, but in the main the 60 amp fuse is a left over...

The rules changed, at one point it did not matter if the sum of the MCB's exceeded the size of the RCD if the DNO fuse was bigger, now it does.

All property should have a minor works or installation certificate raised for any electrical work, it does not matter if rented or owner occupied, as to if a compliance or completion certificate is required, is also the same be it rented or owner occupied, the only time when rental and owner...

Both my son and I have an EV tariff from the same supplier, I pay 8.5p, and he pays 6p for off-peak, as his charger was fitted by the supplier, I do not have a linked charger, so the supplier can select when the off-peak is used. I note Intelligent Drive Pack is currently oversubscribed. Join...
