Condensing combi boiler

Saunier Duval’s Semia Condens combi boiler is available with outputs of 24 and 30 kW and a SEDBUK B rating. They have a stainless-steel recuperator, pipe-connection tails that are clip distance from the wall and a telescopic flue option. Both boilers have a casing 750 mm high, 400 mm wide and 347 mm deep, with a cover over the control panel and built-in timer. To improve reliability, these boilers have an exercise program for the pump and 3-way valve. Self-diagnostics is built in, with a display for fault codes. A built-in 24-hour timer and system bypass remove the need for extra electrical and plumbing work. They have a built-in frost protection and can be installed in compartments without ventilation.
