Nice one. Did you find it hard to fit?
Also don't go melting those plastic balls in the tank. lol
I wondered why everyone recommends the mechanical flange, until it got delivered and i actually held it. Without using this, it would have been much harder.
But the 64mm drill bit made sure the hole was tight enough. I had to sand/file it a fraction untill i knew from the outside that the flange would fit. Then dangled it down on a wire with croc clips till i could hild it with fingers and pulled it through the hole. Tightened the nut up with some ptf tape as well and jobs a good one.
Lol the hardest part was wiring the 13amp plug, as the needed heat resist cable was very stiff to work with.
At 42 degrees, photo doesnt show the steam coming out tank. But its bath temp, very hot to put your hand in. I would definately recommend this avenue for people to try if dont want to use gas.
