New 18, 25 and 30 kW condensing gas boilers for heating and hot water. The technology of using the latent heat of condensation allows you to use gas economically and more efficiently compared to conventional boilers. The average savings for the heating season is 12-14%.

Uniform circulation of the coolant in the heat exchanger eliminates the formation of stagnation zones and local overheating. The minimum wall thickness of the heat exchanger is 3 mm, which ensures efficient heat transfer and durability of the product. The smooth inner surface of the heat exchanger prevents the deposition of limescale. The low hydraulic resistance of the heat exchanger ensures better circulation in the heating system and lower energy costs.
