Suspended condensing boilers are for heating buildings with a heat of loss up to 95 kW. Buildings with a higher heat loss (up to 1,520 kW) can be heated advantageously by ‘cascade boilers’. The output of the boiler can be smoothly regulated from about 27 to 100% of the output and is automatically adapted to needs of the building.

The boiler can also be used for heating water in an external indirect storage tank. In this case, the boiler must be equipped with a three-way valve. The boiler units are constructed as consumer appliances using water steam condensing in the combustion process and are extremely efficient with minimum emissions to the air. The product is extremely efficient with intelligent operation and outstanding reliability.
