Thermex Topflow Pro 21000 (211 022)

Efficient and relatively compact instantaneous electric water heater with electronic control and a spiral flow heating system made of high-alloy stainless steel. It is one of the older models of the Thermex Topflow family of 2018. It features a high electrical and thermal power of the spiral heater (up to 21,000 W), therefore, it requires connection to a three-phase electrical network with a voltage of 400 V.

It is positioned as a product of the middle price category, intended for moderate commercial and domestic use. The main advantage of this device is ultra-fast heating of water, which distinguishes it favorably from storage boilers, which require at least tens of minutes to set the temperature. The Thermex Topflow Pro 21000 instantaneous water heater is equipped with an intuitive electronic control system with a clear LCD display, automatic memory of the last settings and overheating protection.

Flexible modulation of the power of the spiral heater allows you to accurately maintain the set temperature at the outlet of the device. Delivers up to 11.8 L/min at 25°C heating (or up to 8.5 L/min at 35°C difference). The heating limit is 75 °C, which is important for safety (no risk of burns). For a safe connection, a copper cable with a conductor cross section of at least 4 mm² is required.
