Maybe things will get cheaper when kegland Europe gets going.They really know how to charge for brewers
Not BKT they are just passing the cost on charged by Kegland
MAYBE !!

Is it possible to mash without the false bottom and the HED plate?
I wanted to make a BIAB type wort, with a bag of grains inside the mash tube

I would say yes, but why wouldn't you use the false bottom and the heat deflection plate if you already have one ?

because I think it would get too hot... burn the bag of grains
I don't see how two extra barriers between the heating element and the grain basket would cause the bag of grains to burn !
You did say that your intention was to use a bag inside the grain basket (mash tube).

Thats quite a setup you. #Drooling :). As I bypassed the pump for my tap, thinking I am going to replace the tap with a camlock valve and then connect my older pump to that as a backup. As I have already upgraded the recirc pipe to the site glass, I have the old one I can rig as a backup setup.. Something like this. Can also then upgrade the pump.

That would work.
I'd still be tempted to swap that tap out for a dedicated whirlpool.

Do you find whirlpooling in an AIO using a center drain works? I have never tried to whirlpool in it and still get crystal clear beers. Also haven’t noticed the bit of hops mane getting through to make any noticeable taste different (or am I used to it you make me think now haha)

I don't have a centre drain on my system. I think on the US brewzilla thread many do whirlpool.
Gentle whirlpool during the mash helped a lot on my system to balance temperature in the kettle with better mixing. Also has helped by mixing the water / wort between malt pipe and kettle wall.
The whirlpool is after the boil !
During the mash it's recirculation.
Actually in the gen 4, Kegland don't recommend whirlpooling, although many people still do.
I'm still in two minds about whirlpooling in the gen 4 myself.
In a system that doesn't have a center drain, it does makes sense to whirlpool because the hop matter and trub will accumulate in the centre, (away from the the drainage point).

Regular.
Used the whirlpool arm the first few brews, but don't think the built in pump is powerfull enough to create a decent whirlpool on its own. I supplemented with drill degassing paddle, or vigerous stir.
Whirlpool should leave trub (cone) in middle. So on BZg4 wiith centre drain, I guess whirlpool would only be worthwhile on systems with the HED (which I have) where main flow is then around the perimeter.
Have since found that when using hop spider (which is a pain to clean). If i recirculate via spider for a while during cooling (or hopstand), then transferred wort is just as clear as when whirlpooling. So long as I don't pump out the last, maybe 200ml.
Also, as I circulate through my hopspider. It's difficult finding a good time, to put the whirlpool arm in circuit, for sterilising.

Have you thought about a hop rocket/ missile or hop back ?
I find that I get extra flavour and aroma from the hops without any hops left in the kettle plus the fact it does filter the wort to some extent as well.
Just a thought
@Mash Monster how do you use your Hop Rocket? Do you recirculate hot wort through it or is it a single pass during transfer before cooling the wort? Do you still add bittering hops to the wort at the start of the boil or do you get all your bittering as well as hop flavour via the Hop Rocket?
@Wynne I always use the bittering hops direct into the kettle without recirculating through the hop missile.
I only use it for whirlpool additions at 80°c for about 20-30 minutes.
I also run the cooled wort through it into the fermenter but have found with large hop charges it is has on occasion blocked.
I should add that I use a Jaded Scylla immersion chiller to cool the wort because I have to justify the cost to myself by using it!! I’m sure that if I used a counter flow or plate chiller in line with the hop missile things would be easier

Thank you @Mash Monster - it is very helpful to learn from your experience.
How did you get your hands on one of those chillers?
I think people confuse two different purposes of whirlpooling or uses of the term itself. Whirlpooling to create a central cone of trub is mostly pointless in the Gen 4 or even undesirable as it makes digging out the base plate more annoying. Whirlpooling in the sense of creating movement in a hopstand still has value though -- as long as you're somewhat convinced that it aids extraction. I also find that it improves my immersion chilling performance a good deal too.
I find the pump and just angling the silicon hose is good enough to get the latter benefits. People who want the cone seem to be able to do it with the whirlpool arm and maybe some bodging to narrow the opening to make the exit velocity faster.
When they're available I'm experimenting with whole hops loose in the boil for bittering, late boil and hopstand hops in pellet form in a hop spider.
No whirlpool but maybe recirculate through the hop spider during hop stand.
Let the whole hops settle to form a filter bed for trub.
Then transfer to fermenter through counterflow chiller.
