The POLY-81-36 instant water heater operates on electric power and is single-phase. While a traditional water heater heats a large amount of water consuming a lot of energy and time, the instant water heater does not have a storage tank for hot water and only heats the water that passes through it. Therefore, in a short period of time, you have hot water only when you need it and only for the amount you use at that moment. This makes it an economical solution, while also having a longer lifespan as there is no water tank, thus no accumulation of salts in the heating element and other components.

As long as you have the tap open, you will have hot water that is used directly, without mixing with cold water as in a traditional water heater. Of course, a necessary condition for it to operate is that the pressure of the cold water input is not too low. In cases of lower input temperatures in winter and higher temperatures in summer, the performance may vary accordingly.

It is easily and quickly installed in the bathroom or kitchen (application only on one supply). It is easy to use or maintain and serves everyday needs such as hand washing, dishwashing, laundry, or other functions.

It is equipped with a built-in digital display that shows you the water temperature and also allows you to select it yourself. The maximum temperature it can reach for hot water production is 60 °C, while the maximum water flow rate reaches up to 10 liters per minute.

As an indication, 38-42 °C degrees are the standard for shower use.
