Great tip, thanks. I see there's lots of debate about two plugs in one socket. To set peoples minds at rest you can look at the following. This comes from my day job. For any plug to meet the relevant British Standard (BS1363) it has to be able to draw 20Amps total load with 14A from one side, and 6 from the other. So, it is best not to draw from one 2 gang socket two kettle elements, although good quality sockets would probably withstand it without trouble. There is no need to run these two from seperate ring mains, indeed from a safety point of view it's best to have a single circuit to isolate. once again, great tips on the equipment side, thanks for sharing! An RCD on the supply to these would provide additional protection. Modern houses, or ones that have been rewired, are likely to have an rcd in their consumer unit. Take a look and check if you don't know. If there is one it needs to be periodically switched off and on to exercise the mechanism ( A label adjacent to it should have been fitted to tell you about this). if one of these is fitted at the CU there is no additional protection to be had by putting another one by the brew bin. Soldering the large terminals can lead to heat damage of the moulding into which the connection fits, this in turn could cause problems so apply as little heat as is needed to make the solder flow.
