Heaters of this series characterize very simple assembly and comfortable water temperature adjustment what is not common in other heaters of such kind. Thanks to application of non insulated heating element heat water flows out immediately after unscrewing a tap. Additional advantage is consumption of electrical power during usage of hot water only and heating efficiency 98.2%. All the above mentioned features cause that heaters of this series are highly electrical energy saving devices. Heating element structure secures the heater against clogging in result of boiler scale growing from even very hard water. A reed relay flow sensor as well as electronic power switch characterizing itself significantly longer life comparing to mechanical switches (e.g. relays) are applied in heaters PERFECT 350, 400, 450, 500. Unreliable mechanical parts used generally in ordinary heaters are eliminated in result. An anti-air plugging electronic sensor applied to the heating element minimizes damage possibility to the heating element caused by temporary lack of water in water supply system. Application of the above mentioned solutions made possible creation of the smallest and most powerful instant water heater on the market.

Instant water heaters Perfect 450P, 500P are special versions of heaters Perfect 450, 500 Electronic designated for use in shower cabins. Each one is equipped with shower sprayer with specially fit sprinkler holes. This construction allows to receive adequate water stream according to heat output of the heater and to keep set water temperature. Heaters Perfect 450P, 500P Electronic are equipped with housings resistant against water splash of the protection grade IP25. That means the heater is fully hermetic and can be safely splashed with water and there is no danger of electric shock.
