The POW Multi 18 / 12 / 24 LCD is a three phase power current instant water heater that can supply a shower cabin or shower. This a high quality tankless instant hot water heater is an unvented instantaneous water heater for commercial as well as domestic usage. It’s easily connected to the water mains. Due to the compact size of the tank less hot water heater it can be installed in a kitchen cabinet, bathroom cabinet or worktop cabinet. Perfect to supply your en suite, extension, garage, house, office, loft extension, conversion, commercial room or workshop.  

Unlike many other instant water heaters the POW-18 / 21 / 24 LCD has a micro controller with electrical components that operates the water heater automatically. This results in savings in energy consumption, a longer life cycle of the instant water heater and a higher user comfort. 

The outgoing temperature depends strongly on the incoming temperature and the volume of water running through the instant water heater. We therefore strongly advise you to carefully read the technical specifications to find out if this heater will suit your needs before purchasing this particular model. An electric water heater with tank will, of course, provide more and hotter water.

We urge you to refrain from ordering this product if you do not have any knowledge of instant water heaters. Once installed and 
connected to the water main you CANNOT return this instant water heater as we cannot take it back due to hygiene regulations.
