    True, but I would probably go to more places if it was cheaper to do so. Motoring distance is often set on a price point, rather than an absolute milage. It is why mean annual mileage has dropped. ONS figures for all 4 wheel cars.

    Not sure it does. I has a refueling time advantage, but that is about it. I think even a new Leaf would not last for many miles driven flat out. Would be good to see some data on this aspect. I improved the fuel consumption of my car last week, went from 32 MPG to a shade under 50 MPG now. Had a tuppence ha'penny turbo boost pipe replaced. I find that he generally does what he says, just usually takes a bit more time than we think it should. I do about 2 1/2 times your milage, so that would be 375 charges a year, or 5 years 4 months. My car is already over 13 years old. Not read it, but it just sounded wrong. Kind of thing that petrolheads like spouting as truth. Must be these people. https://en.wikipedia.org/wiki/Institute_for_Energy_Research

    I have wanted to do something similar for new products. Most of them are total shit, like my upright vacuum cleaner. The hose goes in at the top, so if vacuuming the stairs, and one starts at the top of them, the f***ing thing falls down on top of you. I can tell you that it really hurts.

    Looked at this a few years back with someone else over at the other place. Think we decided that anything less than 2.5MWh for heating and it was not worth while. One of the reasons that I have stuck with basic storage heater on E7.
  5. SteamyTea
    You can do the same with heating degree days (HDD). It is only good as a rough guide, but may be useful when looking at storage.
  6. SteamyTea
    Right, got the correct data this time. I think this interseasonal storeage is a statistical problem. There are just not enough times when it is cold to replenish a store sufficiently to be of any use. The below chart is shows the amount of time that a concrete brick is either above external temperature or below it. The trend lines, withing the 1 standard deviation limit, show that as the external temperature gets hotter, there are more times that the block is hotter still. The reverse is true for the cooling side of the equation. There are the odd outliers that pop into the 'the other side', but these are probably rare weather events i.e. snow (had some twice), rain (it can cool things quickly), extra sunny days (had a few last year), very windy days (again, there has been a few, not many this last 12 months).

    And according to the internet can clean your bog, patio, coins, cure and give you cancer, cause or reduce obesity, help you concentrate and get a pretty, singing, girlfriend. Ok, I made some of that up. It does go well with a curry though.
  8. SteamyTea
    Surely, when looking at interseasonal heat stores, and assuming you are not after a truely passive system, then everything shoudl be compared to a heat pump. A heat pump is really just taking advantage of stored energy anyway.

    There was a press release from SunAmp a year or two back about barging in a huge heat battery to Bristol. I suspect it just just puff.

    20 MPH is an aspiration speed down here this time of year. Still, high enough to deactivate that 56 dB horn on all new EVs.

    Not on my perfectly functional phone as it does not have an LED for the camera.

    Thought about this last night as I remember a warning going out about Flashlight applications being malware, spyware data slurping and just not worth the risk. So why not make a jpeg that is all white, put it as a shortcut on your phone and use that.

    I just fitted a cheap (£100) shower pump to my vented system. Been working fine since 2008. One day I shall have a look at the little strainers on it.

    And that is how I took the skin of my knuckles the other day Does anyone do a door latch that can sense the MAC address of my phones Bluetooth. That would be handy.

    Had a chat with the head chef of a large local tourist attraction. His argument about not getting induction hobs was that they would have to buy new pots and pans. I pointed out that you don't need to buy 'heavy' stuff with an induction hob as energy is spread across the base automatically. One advantage in commercial catering is that the kitchen temperature is lower when using induction hobs. This saves a lot of cash on calling out the fridge man. As for eye level ovens, they are a good way to get burnt. Top shelf no higher than your waist is the safest. (I hate health and safety generally, but at work I am a real pain about it, have seen what a hand looks like after it has been in a fryer. I was commended on my first aid skills though)

    I think with things like phones it is more about security, rather than new features. Though sometimes they do a major update and the application looks and acts totally differently. And they take away the few features I use.
  17. SteamyTea
    I notice that when I update the applications on my Android phone, almost without exception, there is a second update within 2 days.
  18. SteamyTea
    Right, thought you were on about DHW in general. We have a two small water heaters at work. One is rubbish and the other one is even worse. The instantaneous one either delivers cold water, or scolding water. The larger one with a tank has an odd system when it vents. About 3 minutes after use, it decided to expel water down the pipe. This is because of expansion and over pressure. Heatrea say it is normal, we say it is rubbish as it can leak water onto an area (it has a long pipe so we can fill sink and buckets).
  19. SteamyTea
    Isn't there an overflow into a tundish, or was that just on your system?
  20. SteamyTea
    I disagree. Vented is very simple. One tank to feed the cylinder, a pipe to take the hot water away. And one pipe back to the tank for safety. That is it. No need for pressure reducing valves, expansion vessels, sacrificial anodes, multiple coils, maybe flat plate heat exchanges. We seem to think that complicated is better.

    I think we have come across this fellow before, over at the other place.

    It is not the filler, it is the cement that is the problem. How much can you reduce the usage to. That will probably give a greater saving. It go for lime. Mix and pour. Wait a year. Repeat process.
  23. SteamyTea
    I knew a bloke whose father converted horseboxes to campervans. He must have been good as he was featured in Watchdog.
  24. SteamyTea
    There are some cements that are supposed to be carbon neutral. https://phys.org/news/2015-09-technique-cement-carbon-neutral.html Spoke to this guy a few years back, was very helpful. Not sure if he is still at Sheffield. Dr Ewan A Byars Centre for Cement and Concrete University of Sheffield e.byars@sheffield.ac.uk

    Filler, wire brush with the grain, used teabag to stain it. Will still look like a pegboard eventually.
