I think this was what I used, this is it seems what you are talking about, other than far more expensive, I don't really understand why some compost/soil improver/top soil/Vermiculite/Fuller's earth should be used/not used, for plants. I am not into gardening, but have not option but look...

Nest (Nest is a Welsh Government scheme which provides free advice and home improvements to help you save energy and money.) have put up handrails, and very thankful for them, they look a bit like scaffold poles, but they work and were free. But in the Winter they are cold, and in the summer on...

Would this be because the evaporator gets very cold, so condenses the water out of the air in the fridge? Basic fact at -20ºC air will not absorb any moisture, loads of charts to show relative humidity to temperature. So want to cool the air below the red line to remove moisture and above...

That is a very good point, in fact legal requirement in some cases, if I see an oil spill, I need to either deal with it my self, or report it in writing, even if my job is as an electrician. So there is no reason why in the notes of an EICR it should not report a broken window. And in the...

Thank you, some good points, once we get rain water will be fed to the bottom, but from what you are saying should slowly increase the time between watering them.

I would agree, my point is the EPC does not relate to making people comfortable or saving money, the old idea of a coal fire with high backed chairs to stop the draft, and occupants facing the fire to gain the radiant heat will still work with an electric inferred heater. But remember inferred...

Never mind the hens, I want to keep cool, and it is the same problem, how to use a fan to cool a room, we are all told cooling in the morning is important, this time of year, 5 am until 10 am, after 10 am fans can heat rather than cool. Best seems to be the chimney effect, long vertical pipe...

So I have made a box to take plants to hide the wood used to build some steps, around 8" deep, around 250 litres of compost to fill the box, so wife goes out and gets the plants, which are planted out, same day. This was Tuesday, and clearly been hot since, so watered every day, and the water...

There is a case with storage heaters, where some models retain the energy until required better than others. And heat pumps are more efficient to simple resistive. And some controls are better at reducing the hysteresis as heaters turn on/off. But the EPC rating using some really odd ways to...

If you need to work out the loads allowing for power factors, then in the main you are sailing too close to the wind. This Is not ideal, but it does seem to work. The generators actually had 12 coils, allowing 400 volt three-phase, 230 volt single phase and 110 volt centre tapped. And were...

Single phase, split phase, or three-phase, in the main there is one exciting coil, so the AVR (automatic voltage regulator) can monitor all and take an average, or one and hope even load. Or it can turn the output to DC then back into AC and control each phase with an inverter generator. Until...

Yes I will agree, I did not understand how storage radiators were ever classed as central heating. There were systems with a central heat store and fans to direct heat to rooms as and when required, but most had no central control at all. It does seem that as soon as central heating started to...

Inverters be they static or rotary have been used for years, who remembers the Lincoln welding sets. Be them electric or diesel powered? But the thing which matters, is how the unit is controlled. It all hinges around the AVR.

I have a problem with central heating, nothing to do with the system, it is down to me. Winter I consider 22ºC to be nice, and Summer 22ºC is too hot, but in general the TRV heads control room temperature, and when the room is heated, so not really sure why I need a wall thermostat or...

I would also consider 12 kW to be 4 kW per phase.

Using a PLC you can do all sorts, but most people use much simpler methods, so what is the control voltage, and the power voltage, you say 12 volts, but what is 12 volts? Using a power module you can have multi-voltages, these are 230 volt but you can get 12 volt versions, I just don't really...

Potting compost in and first plant, now down to wife to do the rest. Oh am I glad it's over, does not look much, but glad I have power tools.

Solar and batteries come in varying sizes. Today loads of solar, at moment at limit of inverter, up to now that would run a lot of fans, on the 3rd I had 38.2 kWh but no good talking about me, it is what you have that matters. Other than having fans, batteries and solar panels, you have told us...

Any heritage railways near you? I filled below my patio with ash from the railway, light does not compress much, and once covered with slabs etc. You have no idea what is below.

Just need the triffids, and some more potting compost, but my bit is done.
