Hi everyone
A few days ago I ordered this cheapo tea urn form Amazon( https://www.amazon.co.uk/gp/product/B00IECC0LS/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 ) for my small BIAB batches. It's 20L/5gal, 2400w concealed element and I'm planing to do 6l/1.5gal batches.
Now I've done my homework (I guess) and I understand that I will have to override dry boil protection to allow urn to reach and maintain a good boil.
I also understand that by solving dry boil protection problem I'm creating two new problems:
1. I will probably have wild boils
2. Heating element will work on high temperatures for prolonged periods of time, which is really not made for and why it had overheating protection in the first place - eventually the element will blow/melt
After researching the matter for a few days (I'm not very busy at work) my only solution is to add variable voltage controller/regulator. That way I could run the urn as I normally would until it reaches a good boil and then turn the power down (lets say to 30%) to allow it to just maintain that boil, solving the first problem, and hopefully when turning the element power down it wouldn't run as hot as it would on full power thus solving my second problem as well.
At this point it is very important to disclose that I don't have the first damn clue about anything electrical.
So my questions are:
1. Can someone either confirm that my solution is correct or explain to me why it isn't and help me find another solution?
2. However, if my solution is correct can I use this to control the power? https://www.ebay.ie/itm/220V-4000W-...630273?hash=item44493ed381:g:kCUAAOSwm4tcoce5
3. If answer to first and second question is "yes" could I add a PID as well? The idea is to plug the urn into the variable voltage controller then plug the controller into, lets say, Inkbird (or something more simple) and then plug the Inkbird into the wall socket?
Apologies for a long post, I will really appreciate any help with this
