Description

Description

The model range - 24 kW, 32 kW.

Intuitive operation.

The maximum length of a coaxial chimney is up to 4,5 m, and a separate chimney is up to 20 m.

High unification of components and components for all models of Lemax wall boilers of the Prime series.

Solid heat and sound insulation to ensure acoustic comfort in the conditions of apartment-by-apartment heating.

The ability to connect the Lemax monitoring and control device together with the Lemax OpenTherm module for monitoring and managing comfort in the home (Android and IOS).

The increased volume of the combustion chamber ensures complete combustion of gas, increases the service life of the heat exchanger and minimizes gas consumption.

Double level of safety against excess pressure in the heating circuit, which is provided by a built-in pressure sensor and a relief valve.

Working in systems with high hydraulic resistance allows in most cases exclude the installation of an additional pump.

Structurally protected sensors and sensors from corrosion and scale.

Adapted to gas pressure drops.

The ability to connect a room thermostat to adjust the temperature inside the room with high accuracy.

The extended operating voltage range of the boiler allows for stable operation of the boiler in networks with high and low voltage (185 - 245 v).

Integrated ignition transformer, which ensures stable spark formation and maximum smoothness of ignition.

A bypass is installed in the boiler hydrogroup, which protects the boiler elements from overheating when excessive hydraulic resistance appears in the heating system.

Ease of maintenance of the boiler due to the use of easily removable cladding.
