Anyone got ideas on how to fit one and how to wire it up. Would it work off of an ordinary socket
I've sent them an email to find out if the 3kw version would be suitable for a van tank etc and await their reply.
As for mains hook-up being 3kw as I'm no sparky so would be best to seek professional advice. However I'm aware some using emersion heater elements in the van tank like to use heavy duty arctic cable as the extension cable and run it off a separate house spur/breaker which is then cabled up to a separate outside waterproof socket to plug into. I'm sure there are electrical regs that must be followed regards to this so like I said before best speak to a sparky to do the electrical side for you so it's done properly and safely.
