I was reading about WiFi7 the other day. https://www.howtogeek.com/782023/what-is-wi-fi-7/ (not the most technical of articles, but you get the idea) So why bother with terrestrial broadcasts? Seems the technology is already here to make better use of broad band in the home. There are a number of projects make use of cheap hardware to stream TV. There is also Radio, very cheap and the pictures are better.

ASHP to do both space heating and DHW. Then add PV. Much of it depends on what you think is important. Constant supply of heat Cheapest installation price Most reliable Cheapest running costs Least GHG emissions Simplest to install And many more

Just goes to show how useful proper energy monitoring and basic analysis can be. And it only cost a few quid.

My old (actually younger than me) university supervisor had long email conversations with him. The conclusion was, don't bother, buy a half decent professionally made one. It is a real shame that Proven are no longer about (think they got bought by Kingspan, their 4 kW turbine was rugged and reliable (unlike the 6 kW).

Yes, most of the time a loft, even an uninsulated one, gets quite warm. Also helps the ventilation: a warm roof is, but definition, really just another room.

I can answer that, having been imprisoned in @joe90's attic. No. You may have noticed that his loft is a warm roof, and I think he sucks some of the warmth out of it, as well as the rooms.

Not sure either, though I think the last two versions were just tidying up, nothing fundamentally different.

Ask @joe90 I think he had this problem.

Is there a filter you can easily check to see if there are any bits of the pump in it?

It is You get the very narrow ones then.

Not if the unit containing the propane is indoors. I think there may be a 150g limit. A new record of 9.7g/kW was recently achieved, but current units use around 60g/kW. https://www.coolingpost.com/world-news/propane-heat-pump-hits-new-efficiency-record/

Assuming the place is watertight and it is now just a case drying out, then a tiny bit of basic physics may help. Relative humidity is not the amount of actual H2O in a mass of air, rather it is a ratio of the amount of H2O that is in the air to the total amount it could potentially contain. This is why it varies with temperature. Think of it as a sponge that can hold 100g of water, but is only holding 75g of water, still feels wet. There are three main ways to get rid of liquid H2O, physically remove it i.e. find something to mop it up. Heat it until it evaporates i.e. blow hot air on it. Change the ratio of dry air to wet solids i.e. dispersion/diffusion. Usually we do the latter two in one cycle, so we heat which lowers the RH, then we disperse it into heated air, that is at an even lower RH. Now if you cannot easily run a fan off electricity, some sort of natural ventilation will be needed, careful design can increase this. One way to increase the input of outside air is to have a hole in the wall downstairs, and another hole in the wall upstairs, then add heat near the hole downstairs. This will reduce the RH of the air in the building, which improves the evaporation rate: evaporation takes place at all temperatures, not just above 0°C. By allowing the hot air to rise though the building, while being replaced with air from outside (which will almost certainly have a lower amount of H2O in it), drying will slowly take place. This is why forced ventilation is used, because if you are only taking out a few grams of H2O every hour with natural ventilation, it will take a very long time. If you are on site, or the site is very secure, you could use a portable generator and a gas heater to heat and force the wetter air out. If the structure of the building is very wet, then it will take a long time, and a lot of energy. You may be better off making up some clear windows on the sunny side, and let the sun help (wait till March). Also removing all plaster and getting back to the minimum structure will reduce the amount of trapped H2O that has to be removed. If it is a single skin brick building, make sure the wall 'facing the weather' usually the SW side, has good pointing and maybe a waterproof treatment. Purely as an experiment, it would be interesting to put a sheet of clear acrylic over the outside sunny wall to act as a greenhouse. This could help heat the wall from the outside, while also keeping it dry. Small vent holes at the top would be necessary.

I would have thought that if you know the charging characteristics of the batteries, and the ability for the the inverter to supply, you could find a suitable battery pack. Not that many mainstream makers of batteries once the branded cover is off them.

I thought @pocster was using MAC addresses, but was having trouble.

Is it the LAN/WiFi hardware going to sleep?

Easier installation, less control gear, possibly no need for a buffer or volumizer and maybe cheaper.

Best way to have a relationship, hard to have kids down a digital line. I don't actually agree, while most meetings are pointless and often used to kick a can down a road, when it comes to important stuff, face to face is best. Why we send kids to school. The emissions from flying, in total, are pretty small. Even if every country sent a 747, it would, as a fraction of the whole, be too small to measure.

Part of that is the way future generations emissions are counted. Say you and a partner have two kids, and we each use 1 unit of energy. It is assumed that you inherit half the children's emissions and half their child's emissions. So that will be 3.5 units. But bonkers as it assumes nothing will change in 2 generations. But if you take yourself out the equation, you only save 1 unit. But your descendants are, under the current counting scheme, responsible for 2.5 units. So killing children is a better thing to do, not yourself.

Or Normal for Norfolk.

I had my Corona Booster yesterday, now I am sure I have the Coronas, every one of them, all at once, with some new ones brewing for not so safe keeping. Yes.

Isn't that perpetuating the problem as converting the slurry to methane does not allow the land to become a natural carbon store. Better to get rid of the slurry source, or just spread it on fields (adhering to all the other environmental laws).

I eat about 2.5 kWh/day and my house uses just a bit more. If I 'worry' and hour away on here, this 0.25 kWh. It is how I spotted my fridge had gone wonky.
