There are a series of kits called
Prohibition which do a rum among other flavours, it is an odd method where you make alcohol with sugar then remove as much of the taste as you can with charcoal then add the taste you want, it works very well, you end up with 6 bottles of beverage at around 21% ABV which tastes like the well know liqueurs.
Using a freezer at -18°C the maximum is around 20% ABV and using heat far too easy to make wood alcohol if the temperature is just slightly wrong, and the smell makes it easy to find anyone having a go at making it. So there is no point, home made vodka is called poitin, I did try some when I knew a few Irish lads, but it cost as much on the black market as buying vodka from supermarket, so again rather pointless.
But to make simple beer also needs heat, no heat needed for cider, but it is for beer, the grain is allowed to just start to grow (malting) then it's boiled up, you can draw a few times from the resulting mash, the first is high alcohol once fermented the last is low alcohol traditionally for children, the alcohol stops the liquid going bad. It then takes time first for the alcohol to be made by the yeast when we aim for around 19°C and then for the yeast to clean up the brew a little warmer say 21°C the temperature is important and brewers tend to use fridges with heaters in and external controllers to regulate the temperature.
I tried both brewing in kitchen and brewing in garage the latter with a dedicated fridge/freezer to brew in, and found how important temperature is. You can brew small quantiles without temperature control, but to get a consistent good pint you are surrounded with electrical devices to control temperature.
It is the temperature that makes the difference between wood alcohol and drinkable stuff, and no way could you control a standard boiler well enough to ensure no wood alcohol is produced, so I would not expect that is what is going to be made, it is more likely just for the mashing of the malted grain. Even then the exposed element is a problem, better if you have a easy clean surface.
Oh an tea is the name given to making an infusion with items like hops and adding it to the beer, it is not in brewing actually tea.
