An increase in electricity demand?

"Electric heaters and cookers were being offered to elderly or sick customers, and those with young children."


Certainly if we lost our gas supply, whilst we aleady cook electric, our heating is gas fired CH. To maintain comfort levels I could see three or four 2 kW fan heaters being utilised for much of the day. As for domestic water heating, a kettle or two. 


I seem to remember a previous gas problem where the local gas supplier took round electric heaters to affected houses and blew a few main fuses....???


The photograph of the SGN vehicle with a sat dish and two air conditioners has me wondering. If the a/c units are to get rid of excessive heat build up, then besides the load of the TWO a/c compressors, I wonder what they have in the van - besides a rather large gene??

    From the link to the in-line heater, another product lists:

    The terminal cover is rotatable by 360 deg to ensure ease of installation.


    So, back to where it was originally! 90, 180 and 270 degree options would be better..... Yes, I do think the intention was to describe intermediate rotation, not full rotation!

    I wonder how they know that they have NOT let any air into the pipes? (Other than there being no BANG!)

    The introduction of a LITTLE air is of no consequence, provided that the resultant mixture is well above the upper explosive limit.


    ...and bleeding some off via a suitable gas detector can tell them the concentration of gas. Methane has explosive limits of 5% (lower) to 15% (upper) in air so there needs to be a significant amount of air to give a problem (unlike hydrogen where the limits are something like 4% to 75%).

    Why do you think the minimum ceiling height for habitable rooms was removed from the Building Regulations allowing cellars and lofts with low ceilings to be turned into habitable rooms, particularly in student and other HMOs?

    Yes but 5.16 of ADB requires minimum of 2m for escape route


     




     

    The original minimum ceiling height requirement was in a Public Health Act to try and avoid gas lights killing people, this was written into the Building Regulations then dropped eventually as generally no one has gas lights in homes anymore, though I can think of a few!


    One of the biggest dangers whilst the gas is off is people using other heaters that may give off carbon monoxide without adequate ventilation.

    I like the big copper hot water cylinder that I have, (but there are bigger) that stores hot water. None of this hot water on demand (if all works well) nonsense for me. It stores at least a bath full of hot water. And of course the economy 7 copper cylinders have two immersion heaters in them. so if one fails the other can still work until repairs are undertaken.

    Ah yes, room heaters and water heaters. I think that the latter has been used once in the 20-odd years that we have been here. Our big boiler and cylinder will keep pace with a bath about every 20 minutes. I don't know how much power is transferred from the heating coil to the water, but clearly it is much faster than any electric heater. So potentially with gas failure, the immersion will be on for a few hours per day.


    How will we (or our descendants) cope when the gas runs out?

    Alan Capon:

    Air in the system is only part of it. One of the risks is an appliance without a “flame failure device” fitted on either a burner or a pilot light, and the liability involved with unintentionally filling a property with unburnt gas. Each property has to be visited and the main gas valve secured in the “off” position. Only then can gas be re-introduced into the pipe network. Once the mains have been filled and purged with air, each property needs visiting again, to turn the main valve back on and complete safety checks. 




    A few years ago, the gas board replaced its regulators at the end of the street. They used to be underground, but now they are in a cabinet above ground, which has been erected tastefully. Any road, I had a chat with the workmen and they told me that they had to be careful not to let air into the pipes, else we would all be cut off until every pipe had been purged with nitrogen. Just now, some of the old cast iron pipes are being replaced. Once again, the workmen were happy to chat about their work.


    On both occasions, the supply has been maintained, so no power cuts here. ?

    I can answer my own question.


    Thermco https://www.thermcouk.com/services/  can apparently supply in-line "Geeza Heaters" similar to a Willis with 22mm fittings, so a very tempting form of in-line emergency heater.
