Mains Electric Hot Water Switch

Hi everyone
        After using the MH in fields with no electric hook up I could not work out why we had hot water when we plugged into the mains I then looked at the hand book and found the the electric water heater was fed direct from the mains fuse box located under the wardrobe floor and that it was switched on.I must have been lucky not to have burnt out the element,Has anyone put in an extra switch in a more accessible position
    regards

Most caravan/motorhome boilers have a cut-out that operates when it detects no water is present. Some have a procedure you have to follow to re-start them once the cut-out has operated and others just seem to re-set after a period and carry on working as if nothing has happened.

When we fill up with fresh water the first thing that happens if the water pump is switched on is the pump fills the hot water tank so unless we don't fill the fresh water or don't take on enough to fill the hot tank there should not be a risk of burning out the element. Having said that ,Murphy's law must always be taken into account.

A HW switch with a warning light in a position that can be easily seen, is a sensible requirement. I share your concern about an empty heater tank.
In our Topaz the HW switch, which has a red warning light, was fitted by AS in a cupboard under a bunk and only accessible by lifting the bunk seat ! I relocated this to  the front face of the bunk where it can  be seen and operated without disturbing my wife !

Go to CAK tanks website, download the pdf pages for electrical bits, scroll down until you locate the CBE modular system and find the MCNF Water heater mains switch which includes a 5A fuse plus spare and also a back box.
You now scroll back up to the start of the CBE Modular system and find the surround trimming piece for a single unit (switch) MAT 1NL/G
These are widely used in motorhomes and give a neat professional finish.
I could not ascertain whether the switch had an indicator light. It might be worth speaking to them on the phone to check this and the choice of this combination.

This might help for the switch type, these are in the wardrobe area

The pics in Redwinks post are either   'Clipsal' or 'Edison'.  Both are almost the same and are readily available from caravan shops etc. Clipsal ones have the make shown on the bottom right of the front, Edison is inside the back.
What is needed is a 'switched fuse connection unit' also referred to as a spur box with neon indicator. Both these makes are used extensively in caravans/ motorhomes as indeed are the CBE ones referred to in earlier posts.
other than that it may well have to be a domestic product, mainly the common white plastic but also available in chrome, stainless steel, brass etc.
