What I understand is yes you can add a couple. But I would be thinking about how long is going to take to heat everything up and reach a strong boiling (power on heating elements) also I don’t know if you can add more Extenders to the recirculation arm and again power from pump

I don't see why you couldn't but then I can't see why you would. Doing this would only add liquid volume. Your malt basket will still be limited to its original size.

I don’t see why not I use one without an issue.

If it is 110v it would probably never come to a boil

Yes you can but take care to align everything and make sure you use the seal. It will take longer to reach a boil with the expanded volume and you may need to boil longer alleviate DMS as it is likely the boil will not be as vigorous. You will need to use max watts on the 120V version. I have also done this with the 17.1 gallon brewzilla as well - 240V boils just fine but take a bit more time to reach a boil.

Yes you can... but it will take double the time to reach temperatures.

MoreBeer is now selling an extension for the recirculation arm. https://www.morebeer.com/products/brewzilla-gen-4-replacement-recirculation-arm-extension-stainless-steel-compatible-3.html

I just use a high-temp silicon hose easy peasy.

1st off kegland makes one but MoreBeer isn't selling them here yet. In theory you could make one from a male and female cam lock with hose barbs and some high temperature tubing. You would like need something ridgid to support the entire length from the botto of the Boiler to where the recirculation arm connects to your home made extension. Personally I'm waiting for MoreBeer to get them in just like I'm waiting for the extended malt pipe made by kegland too. The potential scalding injury from a failure while recirculating not to mention the cost of my time make buying one cheap even if I have to wait.
