    It is not straight forward and depends on the stove and whether the slate can get above 100C but you should look at part J of the building regulations (Page 37 and diagram 26 on my online version), I don't like what is in the picture but I am not qualified. We have had at least three installers here that used to post but not recently...

    So pleased that is sorted as I understood @bmp01 and his understanding of engines has sorted one I couldn't fix and you have been more than helpful to me on more than one occasion so I respect both of you.

    Where does the ethanol come from to be cheaper than diesel?
  5. openspaceman
    That link doesn't show the machines, I have two tatty A55 that need a new home too.

    Horrific and I wish you the best for your recovery. When I read about these injuries and worse the american youtuber's death I just think there but for fortune...

    I too have, but don't use, the earlier 602 model from 30 years back. I also cracked the back out by stuffing over long sticks in. I do like the radiant heat from a glass door such tht I wouldn't go back but have wondered about converting it with a heated secondary air insert such the eco version has.

    When, I think it was, pentium processor chips came out for PCs the standard expensive one had a maths co processor. The SX version was exactly the same chip, much cheaper and had the connection to the co processor scratched out on the chip.

    It is the same they just have a battery that fits in the space of the engine bay and transmission tunnel.

    Unless the coving was badly fitting I cannot see how the moisture for the mould to live on would have got there from the inside.
  11. openspaceman
    If you are redecorating that and not having a fitted wardrobe polystyrene coving would insulate the cold bridge from inside.

    @Macpherson as others say you type the @ sign and on my pc as you start typing the username the sever gives suggestions and I pick the right one from the list. Of course it doesn't work if the person has decided not to accept notifications

    I think the 6" and adapter will be fine but @Sugarshaw will know definitively.

    How so? A 5kW wood stove will be evacuating around 6m3 of air out of the house every hour and up the chimney and taking any moisture with it.

    I don't know about the energy used but I expect the carbon footprint tracks it and these modern turbines cover their carbon cost in about 3 months in UK. Part of the shortened life is because the site and permissions are valuable and as turbines have become much larger it pays to swap out a smaller one earlier than it's anticipated life.

    I am worried about doing this on our coombed (sloping) ceilings with only rafters and tiles above in case moisture gets to the lath and plaster and rots the laths. How will you fix the insulation boards and will they already have plasterboard attached? Here is a picture showing how the curtains have acquired the air temperature of the room and the top shows the flat part of the ceiling where I have insulated above with 100mm rockwool (dark spots show where I failed to reach) and the ceiling joist show as darker lines so I should add some more above them. The main point is the coombed part where the rafters here show up as being less lossy than the dark area between them. Also note the dark horizontal line showing a cold bridge where the rafters meet the solid wall.

    53% in hallway at 16C and 40% in sitting room at 19C here. We do have a mould patch inside the front door caused by a winter jasmine wall plant which I like so put up with a dark spot no one can see. My topdon android attachment is a cheap way of spotting cold spots.

    Yes I can see that from what you say, the only advantage in that case would be that the incoming air was likely filtered and because the house was at slightly higher pressure no dust particulates would blow in when a door was opened.
  19. openspaceman
    Yes but condensation becomes a bigger problem as people keep doors and windows shut to prevent expensive heat loss, especially if they dry clothes on radiators as tumble driers (spit) are too expensive to run. Damp tends to occur in cold corners where the temperature drops below the dew point of the air which people are breathing out. This is often at the bottom corner where the cold bridging between walls and floor happens and is often wrongly diagnosed as rising damp.

    Not really as I was unsure of what it was, Mechanical Heat Recovery Ventilation is what I think @Conner is referring to and in a well sealed house is a good thing as it sucks moist warm air out of the house, it exits via a heat exchanger and warms a similar amount of cold air coming in (this which lowers the relative humidity as it warms, thus effectively drying the air). Water which condenses out drips down a drain. Some even have in built heat pumps that drop the old air temperature below zero and the warmth this produces goes back in the house.

    not to mention taper

    Two faces of the same coin. The electricity companies have "bid" to reduce the demand for the grid at much the same rate as the "peaking" generators would be paid to produce the energy. The electricity companies then pass on some of this "saving" to their customers in order to time shift the demand away from the peak period. This is largely because the wind has died down and by 16:30 solar PV cannot contribute. I am told not having to switch on peaking plant avoids a cost of £3/kWh. As it is a cloudy day I will have to buy some electricity today so I will buy it in early afternoon and not need it from 16:30 to 18:00, or indeed for the rest of the night.

    May be better to use electrolysis in sodium bicarb to retain most of the original iron

    Bacterial canker wound which has been aggravated by birds seeking out bugs?
