Thermann Gas 50

Designed to handle long periods of continual use, our 50L Commercial condensing gas continuous flow unit is ideal for businesses that need high volumes of hot water delivered efficiently. These units incorporate larger, more robust heat exchangers for high performance and long life. The innovative condensing technology reduces wasted energy by pre-heating the water using heat from the exhaust gases, making them 15% more efficient than conventional gas continuous units. With a 5-year warranty on the heat exchanger and 2 year warranty on heater parts and labour, the 50L will reliably deliver all the hot water you need.
