The Thision S Plus range of wall mounted, gas fired condensing boilers provide the highest levels of seasonal efficiency, a low environmental impact and lifelong reliability. The stainless steel heat exchanger is constructed using multi-pipes with generous wall thickness for strength and durability. These are configured in such a way to return the highest levels of efficiencies and are spaced to optimise flue gas temperature zones to ensure extremely low NOx and CO emissions for protection of the environment.
