The Thision S Plus boiler is one of a range of three wall-mounted, stainless steel, fully modulating, low NOx, gas-fired condensing boilers, with maximum outputs ranging between 33.6 kW and 52.9 kW at 80/60°C ΔT. The boiler uses a downward firing pre-mix burner, which, combined with precise gas-to-air mixing, results in low environmental impact. 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 as to return the highest levels of efficiency. The burner air/ gas system includes a flue gas non-return valve as standard, and the appliance is configured to use industry-standard 80/ 125 flue components. The boiler is supplied in one piece with a fitted, robust and stylish outer casing fabricated from stove-enclosed steel sheet. The boiler includes an integral pump and a diverter valve for DHW control, which can be added as an optional extra.

Features and benefits:

• Fully modulating burner with precise gas-to-air mixing.
• Low NOx emissions ranging from 21.0 to 28.0 mg/kWh.
• Seasonal energy efficiency for room heating of 98%.
• Stainless steel heat exchanger with multi-pipes and generous wall thickness.
• Includes flue gas non-return valve and uses standard 80/ 125 flue components.
• Seasonal space heating efficiency class rating of A.
• Robust stove enabled steel sheet outer casing.
• Integral pump included; diverter valve for DHW control optional.
• Supplied with QAA55 room control unit and QAC34 outside air sensor.
• Versatile operation between Δt 15°C and Δt 25°C.
