    I have been trying but to start with most on here argued for zero carbon, that has now changed, early on I was a lone voice.

    No argument about the particulate, etc, pollution aspects of burning wood. Personally, I think all wood burning (and most other burning) should be considered off-topic for a green forum. I usually skip threads on the subject here. Also, the embodied carbon of wood chips shipped from America or wherever really has to be considered - I haven't checked it out so don't know off hand how significant it is.

    There's also the concern that removing wood from a forest area takes away not only the carbon and oxygen extracted from the air by photosynthesis but also trace chemicals from the soil which should be recycled as the wood rots.

    (Perhaps the ashes should be collected and recycled properly. Does that ever happen?)

    However, burning wood which would have fallen down and rotted in the next decade or six is not even close to being as much of a net release of COâ‚‚ into the ecosystem as burning the same quantity of carbon as coal, oil or natural gas as it's already in the system of stores which are closely coupled with the atmosphere. At most setting up to do this makes a one-off reduction to one of the stores (by thinning out the forest).

    Here's an example of burning wood which I think is only a small producer of net COâ‚‚, much less than the amount burned or that which would be released by burning, say, natural gas or propane: http://mistersustainable.blogspot.co.uk/2015/05/firewood-it-warms-you-twice.html

    Tony would your situation be prejudiced if the facts were to see the light of day ?

    Is there any way to establish the weekly/monthly fuel burn or RHI payment and the number of users of this establishment.


    I am old enough to put my head on the block if necessary nothing to lose anymore.

    I am not involved but know all about is a someone I know is trying to sort out the controls there, they also loose lots of energy

    I can try asking for release of details but I am more interested to know how widespread dumping hot water is than blowing the whistle on this particular case.

    Presumably someone, a commercial heating and plumbing company must have advised the set up.

    The timings seem extraordinarily long to me. 5 minutes is a LONG time. They could save bucket loads just by dropping the timers by 75% !!

    As it's a local authority then freedom of information should apply?

    It may be that publicising one case will cause many more to appear from the woodwork.

    Tony - you don't mention if this is a "quality of service" issue or a "water hygiene issue" - as a LA, they will be very keen to meet Legionella guidance in such documents as Approved Code of Practice L8 (as an example)

    Given this is a hostel/hotel and almost certainly has showers (which create aerosol), the dumping may be simply to get the sentinel outlets to temperature in a defined time

    It's a rubbish design for sure - but HSE prosecutions of LA's over legionella risks are reasonably common - so you may have a perverse outcome here driven by fear or prosecution

    Presumably you do know the reasons why this course of action was taken

    Dumping HWS is not that uncommon for hygiene reasons and for safety reasons - so dumping to maintain temperature for avoidance of legionella proliferation or dumping of HWS to reduce temperatures locally fir avoidance of thermal damage or scalding risks

    If you want an extreme example, then washer disinfector systems for medical endoscopes drives water up to at least 70C for pasteurization purposes and then dumps at the point of entry to the washer disinfector until its down below 35C (the endoscopes are easily damaged by thermal stress)

    There are a large number of endoscope wash systems across the NHS estate

    Regards

    Barney

    On a completely seperate angle - Pharmacuetical companies operate what's called WFI (Water for Injection) systtems. Under the rules, the water (and we are talking tons of water) in the system must be heated up to >80C every 24 hours

    As much as I dislike these tossers, they do have a good database.
    Can this local authority be identified on it and then we can see the scale of the problem:
