I have watched this video and your hobgoblin extract video. Both really excellent and a big help getting my first brew together, you have inspired me. One question I have is regarding the boiler and kettle elements. I have built my own boiler and looks identical to yours, cost me about £40 in total. Its water tight and I have tested it boiling a small amount of water. Did you run into any trouble powering it? My elements are 1.5KW each. When plugged in I can feel the plug and wire get warm to the touch. I am scared of burning my house down :-D Did you receive any advice about not powering yours from the same double socket or the same ring main?
