    Let us know who you use for the kit if you go that way

    There is another about pumping water to lift a weight, similar to Gravitricity but using water. Flow batteries seem good too but I need to do more research. They should use materials that are abundant, I see Vanadium costs are now through the roof.

    https://www.gravitricity.com Was it the above?

    Thanks, I'm just interested as Lithium Ion seem to be limited when there are so many other viable solutions

    Has anyone experience of flow batteries and specifically vanadium redox flow batteries. Just after any experiences or information. What do we think will happen with Vanadium prices as they have risen recently. Perhaps Zinc Bromide flow batteries would be better as zinc is relatively abundant. Just curious!

    Blown cellulose is used widely in America in timber framed buildings. I must do some more research

    You could Larsen Truss and blow in cellulose, its fire rated??

    If you do find it, let me know as I've recently moved house and want to set up some sensors to monitor temperature, humidity and general air quality

    Everything with EnOcean is a struggle. For such an innovative company they don't have the greatest sales personnel. I speak from commercial experience
  11. Mackers
    I like that idea
  12. Mackers
    Very good, how do you purchase those
  13. Mackers
    What about something like this? Adafruit
  14. Mackers
    It's a bit more complicated than that. We'd need more info on your build and what you want?

    I specify plenty on commercial projects that are linked to access control systems. Not that make but im sure if you do the usual checks and look into what the security is around coding of swipes it should be ok.

    Welcome, you'll lose days reading info on here!

    Thanks for link too☺️

    Thanks but this is a new build. Im starting by getting ideas until the client has decided on layout etc. There will be an extensive BMS system with analytics of data for predictive maintenance etc. Also some new valves and ideas around VFDs for the AHUs and pumps. Im really just brain storming to get some ideas to research further. I did my MEng in Energy so very well versed in PV etc but never hurts to immerse yourself in some research

    This is why I started this post, thanks. Just looking at various options to save energy on an Industrial Laundry. Initial ideas are preheat for boilers, energy recovery from the steam system. Very early days but open to suggestions. Perhaps recovery of energy from high level warm air somehow.

    Anyone heard of these? Just doing some research. https://www.google.co.uk/url?sa=t&source=web&rct=j&url=http://www.futuregreenenergy.co.uk/wp-content/uploads/2016/01/Daylight-Energy-Booklet-2015-1.pdf&ved=2ahUKEwiFwsbSp8DcAhXQTMAKHS2sC24QFjAFegQIARAB&usg=AOvVaw1bcPs0yY51Rq4FMJUNv_kd

    BS marked or anything?
  22. Mackers
    I would use Cellulose but I think installers is the issue or lack of
  23. Mackers
    I can see your logic. Check out Larson Truss for the DIY option.
  24. Mackers
    Any truss manufacturer could make that. What about using I-Beams or webbed joists or just make them yourself?

    Try Holders Components for prices
