For a long time, the boiler gave people the impression of a black and black machine, taking much floor area, influencing the image of the place. So people put the boiler in the corner that is not easy to be seen or in the boiler room. These problems were solved by the advent of the Fangkuai Thalia series. The elegant and generous appearance design, the subversive structure design and the application of innovative technology make Thalia series become one of the best choices of vacuum hot water boiler.
