The heating medium-water boils at low temperature (80~90℃) to generate steam. The steam and heat exchanger perform condensation heat exchange to release all the latent heat of vaporization in the steam. The efficiency can reach more than 93%.

The heating medium-water does not participate in the heating system. The system has a small amount of water and vaporizes at a low temperature.

When the boiler is operated in a sealed state, there is no water loss, so the investment and operation cost are minimized.

Different temperatures of hot water can be provided.

The boiler operates under negative pressure, high safety and reliability.

Ease of installation, reduce costs by up to 30%.
