Stupid question probably:
Couldn't I use it as default neutral and heat the water with it?
Edit:
Obviously not the gas pipe itself, but I'm not really familiar with gas boilers, do didn't think of that
But can't I use a normal/real neutral to heat the water?
This is very obviously bullshit, what I'm thinking, but if the stuff in the house still works, while heating up this tube that much, I'm wondering, if that energy can't be used somehow
