Nope, Aviva would opt for a default rather than guaranteed income, I've been paid by DWP for 5 years now without having to fill in forms of any sort. Cut my driving licence in half and sent it off too.

Stop it @Stubby I'm supposed to be filling out the form for my pension which starts in December and if I make similar mistakes in that...

Depends on who cuts out the branches and stacks the cord, If you cut the middle of the bend you get 70% stacking, cut either side of the bend and it drops to 50%

Actually 1 litre of beech or oak do weigh about 1 kg

I will edit that 😀

Yes but it's the same as 1 litre of water weighs 1kg but I did make a mistake in my off the cuff reply from having an addled brain, I blame the pneumonia vaccine ;-). It was just as well @gdh queried me.

It depends on the bits of wood to some extent and I made a mistake as I assume fresh wood instead of 20%mc wwb We can say wood is carbon, hydrogen and oxygen plus the hydrogen and oxygen in the 20% moisture. The ratios are approximately 5 carbon, 7 hydrogen and 6 oxygen. that give a molar weight of 5*12+7*1+6*16=163 when that burns it produces 3.5 H20=3.5*(2+16)=63 or 38% of teh dry wood. So with wood at 20%mc wwb thats 0.8kg dry wood and 0.2kg water burning to give 0.51 litres of water. Fresh wood at 50%mc wwb produces 0.7 litres which is 140% of the weight of dry wood burned.

It's because the steam condenses and settles in the exhaust before it gets hot enough to pass out as a gas, wood at 20% moisture produces about 1.5litres for every kilo burned

You need to ease it just over compression, let the recoil retract and then pull it. I have a jonsered 920 that I can't seem to get rid of and it is the same. It would never have been a problem to me twenty years ago.

Obviously it's as you say and just a bit of fun. I don't believe stickers or most signs we see in our daily routine are of any benefit if initial training has been understood and taken in.

I wouldn't discount the possibilities of something being possible, @trigger_andy has pointed out the circular saw stop and I cringed when I saw the video of the designer triggering it with his finger but it was incredible. Similarly professional motorcyclist now have suits that inflate explosively if a crash is detected OTOH a sticker may work

Even as late as 1994 people weren't using chainsaw trouser here, prior to 1981 they were unheard of here.

I'm sure the little difference it will make as earth orbits around increasing entropy as it dissipates the energy it captured from the sun is in the order of gnats pissing. The bottom of the pond will not grow colder than 4C until the ice thickens so deep that there is no liquid water left.

Yes it could happen but most collisions are between vehicles and vehicle hitting crash barriers and seldom do they take down bridge abutments. I wonder what the life of a HV overhead wire is and whether the wear is related just to rubbing AND/OR current passed . When I rode a train cab diesel electric it took 2000 amps to get it rolling then very little on the move. This is the nub and in this case it's real time use of electricity, not off peak charging when everyone is asleep. I was not sure whether the lorries were EV with battery or had a diesel when not connected to the overhead but the figures would be interesting. Laden a 38tonne lorry gets about 6mpg, that's an impressive tonne-mile figure and about 8 times more than a typical car uses. Cars do about 5miles per kWh and have 20-30kWh batteries. So if the lorry has 100kWh battery it can do about 62 miles between leaving the overhead and getting to another charge point assuming the initial overhead running provides enough to fully recharge the battery. Of course from a pollution point of view moving the power production to a centralised system is likely better than having a diesel running but from a climate change CO2 dumping position do all the production and transmission inefficiencies match the non optimum running of a diesel in a lorry? I doubt it so somehow the electricity needs to come from a non fossil fuel source..

Like this?

Okay sorry if I misinterpreted. So we agree good insulation works both ways and a house with high thermal mass will have less temperature fluctuations with exterior insulation. I still haven't attempted wall insulation for my solid walls because it would destroy the look of the two tone bricks.

My second try at replying as lost first in cycberspace. Twenty years ago I did a lot of work in UniS grounds and woodlands and wasn't aware of that. They now have a woodburner at the sports complex. I guess the sizeable lake is also heating a sizeable building. The thing about a natural pond is that the coupling with groundwater exchanges more heat and as @Billhook says a running river is picking up heat as it travels. Also water is good at absorbing infra red radiation from the sun. I wouldn't worry about solar thermal over heating in this country and even if it did there are ways to deal with it, freezing would be a bigger worry. PS I experimented with flat plate collectors but with a small South west facing roof opted for solar PV for the available space.

Saves your back too. I find the type you linked too flexible so prefer the all steel ones but you do need to stiffen the stupid attachment by welding a bit on to stop the flattened tube flexing. I have had mine for over twenty years and they used to laugh at me when I took them to domestic jobs. https://m.media-amazon.com/images/I/61K7TLZi1IL._AC_UL320_.jpg Very good for picking up dog turd too

It's interesting that I seem to hear more problems with ASHP than GSHP but that may be because they tend to be much cheaper to install. My first experience of GSHP was 30 years ago on a big house, offices and garden of a property developer. The pipes were under about an acre of lawn. In deep winter they tried to heat everything, including a pool and stables and this resulted in the soil around the pipes freezing and raising ridges in the lawn. This was entirely a problem of the development company owner not understanding the science and he scrapped the installation rather than accept its limitations and add an alternative for cold weather. I came across a similar thing when my brother converted an old house into 8 flats, he did not take advice and fitted radiators instead of underfloor, he also used the ASHP for domestic hot water whereas a point of use hot water would have been more sensible. Worse still was because 8 flats domestic hot water was stored in a common tank the temperature had to be raised electrically each day to eliminate Legionella bacteria. Had the ASHP only supplied underfloor heating it would have been adequate most of the time. Instead it was ripped out at great expense. The interesting thing about ASHP is that the air temperature varies much greater than the soil even only six feet down, so in cold weather the GSHP has less work to do as long as the heat exchange surface under ground is adequate. Both depend on the sun. Oddly a lot of folk seem to believe that GSHP get their heat from the earth's core[1], there is some but it's only about 50mW/m2, the vast bulk is stored up in the surface layers in warmer weather. It strikes me a big pond would be an ideal source as the bottom layer would remain at 4C even as ice thickens over the top. [1] this reserve of heat in hot rocks is accessed because the hot rocks have been heated for millennia but as the heat is taken out, in Iceland as high pressure steam or low temperature water from flooded mines, the rocks cool faster than the heat coming in from the core, so the heat is not sustainably mined any more than an aquifer in a desert region is mined for water.

You too are missing the point like @Big J's guardian reader. As @Woodworks says if the stonework is insulated outside the insulation can prevent solar gain, thus keeping the inside cooler

This is exactly the situation we decided air circulating pellet stoves were ideal for, a 10kW fast heat up of the air space which tailed off as horsed of sweaty bodies contributed their 200W to. We imported 25 in about 2000, I still have the demo unit idle in my shed, but take up was not good and the pellet price shot up from£70/tonne.

and Gaia kicking back.

Yes but fundamentally they are the same a fridges so I expect only minor tweeks. They will be "tuned" to give the best result (Coefficient of Performance) at a given output temperature and temperature of whatever the collector is outside. This is unlike to exceed a COP of three and a bit most of the time, so if we ignore the substantial capital and replacement cost with electricity at 22p/kWh the heating won't get better than 7p/kWh. Drop to a delta T of over 20C then what happens? So it looks like the intention is to let gas rise from the current 4p/kWh (I still pay 3p till April) to above 7p/kWh. If you accept the grant for a heat pump then you lose your gas connection forever. As to hydrogen; I do not think it can use any current gas grid as it finds leaks much better than methane. I do wonder why the capital invested in the natural gas network is not worth finding a way to synthesise methane from all this hydrogen we expect and carbon from plants or indeed oil. With the move to electric cars I think a domestic CHP becomes worth looking at even if it is internal combustion based I bet the constant running for short periods charging a battery will compensate for the varied conditions a IC car has to deal with and running on methane it will be very clean plus heat the house. See above and for the small amount cooking uses LPG will be around for a while. A decent induction hob should be up with gas for better heat control

AFAICS there's not much not to like about underfloor heating apart from, perhaps, places that are only occupied for a short while, village halls, scout huts etc. I was working at a large townhouse yesterday, cutting some ash from the felling of an open grown tree about a year ago, sizes were from 4" to 18" in a neat stack of about a cord. Split faces were about 36% mc on my meter,Took me 4 hours and three tanks of fuel but that won't last their 2 stoves and jetmaster long. Anyway the house was 50 metres from the gas main and would cost £6k for the connection so when the new owner moved in he elected for an air source heat pump. It looked like 4 of those fan-coil air conditioning units you see on office buildings. A bit incongruous on the outside of a Victorian, flint knapped building. I'm biased but thought it looked worse than the 16 solar panels I have on my house. He did say that he was surprised at how much electricity he was using but wouldn't go into detail, I imagine it was still using radiators.
