Boiler questions

[Archtronics]

Hey

So I am embarking on the construction of my brewery, and the obvious route to me is to first get the boiler so I can extract brew then obtain the rest of the kit from there.

Anyway a couple of questions:

Say I wanted on average do 50ish ltr brews then what size boiler should I aim for 70ltr?
Old Kegs seem like a cheaper/ better alternative to the Nordic pots due to having a raised bottom to allow for piping etc, however there seems to be some legality issues with this?
How come very few people insulate there boilers surly this improve efficiency and saves on the electric bill?

Thanks

A quick note in case anyone suggests I refuse to go plastic, hot liquids and plastic do not mix in my opinion.

Thanks

Yup, IMHO, you need 70L or bigger for that brew length.

Old Kegs seem like a cheaper/ better alternative to the Nordic pots due to having a raised bottom to allow for piping etc, however there seems to be some legality issues with this?

Bit of moot point really as, AFAIK, the most popular 'available' UK keg size is 50L, so too small for your needs. WRT the legality & cost, I 'll let you do the research ...you may even find some larger kegs

How come very few people insulate there boilers surly this improve efficiency and saves on the electric bill?

99.9% of brewers do not use any form of control over the heating element(s) so the amount of power used (electricity consumed) is fixed... 2.4kW, 3kW or twice these for 2 x elements... you either have a roiling boil or you don't. Insulating the boiler would probably speed up the initial 'up to boil' time but after that - the other 60-90 mins - it won't help your leckie bill (IMHO of course).
