MEX Instant Water Heaters
Warm stays warm No cold surprises
Mid-shampoo, someone opens a tap down the hall, and cold water hits your back. A flow sensor holds the temperature right where you set it
If two bathrooms run at once in your house, you know
You get the temperature just right, then the pressure drops a little and the water turns cold on you… so ours holds it and stays steady The room you use every day should not be one you gamble on.
Pick a series, then see the colour it really comes in
All five carry the same safety package. What changes is the face of it, how you set the temperature, and what comes in the box.
One unbroken sheet of glass, and a number that means something
The front is a single piece with no seam, so the only thing to look at is the digital pad. Set it anywhere from 32 to 48 °C and read the number back, instead of guessing from where a dial points.
The whole unit goes flat, and the LED is the only thing that lights
Idle, CRAVE is one flat panel in a single colour. Switch it on and the LED display comes up with the setting you chose — the only point of light on the machine. Inside, the water side and the electrical side are built as separate modules.
Square, plain, and the only one that comes in titanium
A soft-cornered rectangle with nothing on the front but the control. What sells this series is the finish — titanium is hard to find on an instant water heater, and it lines up with stainless taps and rails without a compromise.
The only series here that comes in gold and silver bronze
CODE took a Demark Design Excellence Award in 2013. A bathroom built around bronze or gold taps normally has to settle for a white or black heater because nothing else exists. This series answers that directly.
The only series with two-tone colour, and no square edges
Where the rest of the range runs flat and square, COCO is small and rounded — it sits on the wall without taking a small bathroom over. It is also the only series that pairs two colours, by variant and wattage.
The part MEX backs for five years is the one you never see
Water does not run straight past the element and out again. It follows a spiral path through a copper heater tank, so it stays in contact with the heat for longer and copper moves that heat into the water rather than holding it. That is the part MEX warrants for five years, against two years on the rest of the unit — and it is why the temperature holds instead of drifting while you are still under the shower.
A leak of 15 milliamps and the power is gone in a tenth of a second
Every MEX instant water heater carries an ELCB — an earth leakage circuit breaker that watches the current going in against the current coming back. The moment 15 milliamps goes missing, it drops the supply within 0.1 seconds, faster than you would feel anything. A safety thermostat sits behind it and cuts the machine out if the water ever runs abnormally hot. On CRYSTAL and CRAVE the ELCB carries a test bar, so you can press it once a month and see for yourself that it still trips.
A German inspection body signs off every model, to IEC standard
TÜV SÜD is an independent testing and certification body, and every MEX instant water heater in this range carries its mark against IEC standard — the international rulebook for electrical appliance safety. In Thailand the same units are certified to TIS 1693-2547, and they have passed the efficiency test set by EGAT and the Ministry of Energy that earns the number 5 energy label. Behind all three, MEX warrants the unit for two years and the heater tank for five.
Set the temperature on a screen, and it stays where you left it
CRAVE is the truly digital one. An LED display shows the setting, Rapid Preheat gets the water warm without the wait at the start, and Electronic Temperature Control holds it there instead of letting it drift. The water side and the electrical side are built as separate modules, the housing is sealed ABS to IP25, and the ELCB Advance carries a test bar. If something is wrong it tells you which thing, with error codes E1 to E6 on the same screen. Two variants, 3,500 and 4,500 watts, in Sapphire Black or Moonlight Silver.
