Posh flats in PZ have plank decking. Rain filters though the cracks in them, then drips for hours after a short shower. I am not a drainage engineer, but I would look at an imperable base and some sort of conceled guttering and drainage. I am also not a house designer, but often I see balconies with walls on them, so when sitting in a chair you cannot see over them. So glass, which I think looks really naff and passersby can look up your kilt.

Do you know your day usage percentage. Reading the meter will tell you, but only over the life of that meter. I currently use about 70% during the night, but I only use 68p/days worth. That is a mean (summer) price of 23p/kWh. Come winter, when I use 15 kWh/day, but 85% at night, leaving ~2 kWh/day at the 28p rate, that gives a mean value of 21p/kWh.

There was a report about buffers, was not posted up by me. But I think I downloaded it. hot_water_cylinders_buffer_tanks_heat_pumps.pdf

To be more scientific, the thermal losses from the buffer have to be taken into account. These losses may be useful i.e. heat the house, or they may not i.e. overheat a section of the house. My fridge, which is just a heat pump, comes on for about 10 minutes every house. Been reliable so far.

They have no place in the rural environment either.

I am not sure, printed out the report and intend to read it on the weekend.

Based on what I said a decade ago, but it was only 50 cars. Vehicles have to comply with much stricter rules and most have had particulate filters fitter for the last two decades. Free air combustion and compression combustion cannot really be compared. Yes, and for the righth reasons. Getting rid of domestic combustion technolgies will benefit us all in the medium term. Those NOx emissions will virtually vanis from the towns and cities. Farmers are going to have to work hard to cut their NOx emissions though, not that rural people care. They like to think they always get the sticky end of the stick.

Should work well with this: https://newatlas.com/mit-wifi-people-track-walls/40158/

Sounds OK, but maybe carefully screw the GRP in place, after drilling clearence holes, it can split easily.

You need to listen to today's Woman's Hour. https://www.bbc.co.uk/sounds/play/m001b44s?partner=uk.co.bbc&origin=share-mobile Here is a quick screen capture of the relevant topic. Emma came up with a fantastic reply at 10.33 AM in the 18th August, 2022. Radio gold.

About 0.4 kWh per recharge cycle in my case. That is on a 200 Lt cylinder. Not sure what my volume of water usage actually is, 50 to 60 litres of greater than 35°C. I really hate seeing heated water go down the plughole as it comes up to temperature. Probably why I like baths so much, less waste, in my mind, but not in reality.

There have been many reports and studies about adding charcoal to soil to improve it. Jury is out still. Much depends on the condition of the soil in the first place. My view is that there is a lot more to soil fertility than just the base elements. So enzymes/proteins mix, mechanical properties, ion/electron exchange etc. If soil science was simple, we would have cracked it by now. One thing that adding charcoal does well is help water retention (useful for some plants, deadly for others). But there are probably better, cheaper, and more environmentally better ways of doing this than combustion. https://energy-surprises.blogspot.com/2012/05/how-green-is-my-charcoal-barbecue.html If you want to help restore the planet, just leave it, or a bit of it, alone.

How is the GRP trim going to be attached? Mastics or mechanically?

Ours comes from Newlyn.

Other way around. Coal is better than wood. A lotof it is down to the energy density of the fuel. Chemically they are the same thing, carbon (major consituent) and hydrogen (minor constituent), 'pushed' together until they fuse, then pushed some more. It is very scalable and a tiny marginal price as well. It is hard to buy a battery that storges just 0.5 kWh one hour, then magically expands to 20 kWh another hour, all at 28p/kWh.

Ask him about Poisson Distribution. Can calculate 'time to failure' and 'time between failure'. This distribution is used quite frequently in reliability analysis. It can be considered an extension of the binomial distribution when n is infinite. It can be used to approximate the binomial distribution when n > 20 and p < 0.05. If events are Poisson distributed, they occur at a constant average rate and the number of events occurring in any time interval are independent of the number of events occurring in any other time interval. For example, the number of failures in a given time would be given by: http://reliabilityanalytics.com/blog/wp-content/uploads/2011/08/poisson_f_of_t.png where x is the number of failures and a is the expected number of failures. For the purpose of reliability analysis, this becomes: where x is the number of failures and a is the expected number of failures. For the purpose of reliability analysis, this becomes: http://reliabilityanalytics.com/blog/wp-content/uploads/2011/08/poisson_f_of_t2.png where: λ = failure rate t = length of time being considered x = number of failures The reliability function, R(t), or the probability of zero failures in time t is given by: http://reliabilityanalytics.com/blog/wp-content/uploads/2011/08/poisson_to_exponential.png or the exponential distribution. In the case of redundant equipments, the R(t) might be desired in terms of the probability of r or fewer failures in time t. For that case http://reliabilityanalytics.com/blog/wp-content/uploads/2011/08/poisson_reliability_cumulative.png

I live alone. I did have a lodger once, and once I had beaten her into submission, the annual usage was around 5 MWh, lat year I think I got it down to around 4 MWh. So far this year (228 days) I havve used 1892 kWh, which is better than I imagined. I also don't live in the cold, and now I have removated my back door, I should save a bit there (had a 6mm gap and the bottom and the seal had totally failled. I do try and think about what I am doing, so no use of a tumble dryer, I use a clothes line, not much oven usage, induction hob, cook twice as much paster and sauce as I need, then either 2 minutes mircrowave or eat it cold. I wish my car usage was the same, last week I used arround 270 kWh of deisel to travel 320 miles. Cost 50 quid. At least this month I am not travelling the 600 extra miles to see my Mother every weekend.

Back to summer energy usage. Last week I used a total of 14.7 kWh (a new record low for me) 68% of that was at night on E7 (so mainly water heating and the washing machine). From the 1st May to 1st August I used 359 kWh, so 3.9 kWh/day. I cannot remember when I put my new imersion heater timer on, I think it was about 15th May. Just had a look after tha date til beginning of August and my daily usage is 3.5 kWh, so a 0.4 kWh/day saving on DHW. 8p/day. Saved £6.25, or close to half the price of the timer. Result.

I do Diesel is 0.25 kg CO2/kWh Bio-Diesl 0.25 kg CO2/kWh Timber is 0.41 kg CO2/kWh Natural Gas is 0.18 kg CO2/kWh https://www.engineeringtoolbox.com/co2-emission-fuels-d_1085.html Particulates are here, just got in and too tired to go though it. Worth noting that particulate emissions from vehicles and boilers are not the same, for many reasons. So the VW scandle is not applicable to bomestic boilers, or lare scale ones for that matter. https://uk-air.defra.gov.uk/assets/documents/reports/cat11/1708081027_170807_AQEG_Biomass_report.pdf a snippet A GJ is 278 kWh So Timber PM2.5 2.2g/kWh Oil PM2.5 0.0115g/kWh Gas PM2.5 0.0018g/kWh And people wonder why they are told they are dangerous. Even putting coal on you fire is an improvement. Stop thinking it is safe, it just isn't, even if you are rural.

It would have to settle for at least half an hour before the readings have any value assuming it is heated from the base.

4.2 [kJ/kg.K] x 210 [lt or kg] x (65 - 15) [delta °C] = 44,100 kJ Convert to kWh 44,100 [kJ] x 0.00027778 = 12.25 kWh So assuming your water delta T, difference between mains temperature and final temperature is a bit lower. About 37°C, before system losses.

@Carrerahill, @Mr Punter We really need to grow up, these are serious times.

Is the house in Ealing, and is it owned by a young lady.

You didn't live in a farming area during the BSE culling and disposal then.
