Wherever smaller volumes of warm water are frequently required, the mini electronic instantaneous water heater is the perfect choice.

The DEM delivers water at the electronically controlled set temperature without having to overcome long supply lines with resulting line losses. There are also none of the common water and energy losses resulting from manual temperature adjustment. Consequently, the DEM electronic is ideally suited to washbasins, where a constant outlet temperature is preferred. The appliance can be mounted undersink or oversink; connection to the 230 V mains is also easily accomplished.

Why choose the DEM 6 unvented mini instantaneous water heater?

  • Electronically controlled mini instantaneous water heater with 5.7 kW output
  • Suitable to serve 1 single basin
  • Accurate temperature delivery up to the maximum output
  • For supplying a single hand washbasin with maximum efficiency
  • Temperature limit adjustable between 30 °C and 50 °C approx.
  • No standby or distribution losses
  • Suitable for oversink and undersink installation with a single appliance
  • Can be used with commercially available taps

Good water heater for under sink. Would have liked it to be a bit warmer but does the job.

Excellent service from the Heater Shop. Order placed and item received within 48 hours. Would have been next day but the delivery person said he didn't have time to deliver when he was supposed to. No fault of the Heater Shop.

Thank you so much for this great 5-star review. We really appreciate your business and helping to share the word about Heater Shop.

Installed and operating although the fibre washer on the hot connector had to be replaced with a rubber washer. It was bought to replace one from another manufacturer which repeatedly failed (triac failure) after about 12 months use - 4 times in 4 years. It remains to be seen how reliable this one is.

Very prompt, efficient delivery

Thank you for this positive review on our delivery service. We highly appreciate this.
