Combi Boilers

Baxi Quinta Ace S

Available in seven outputs, the Baxi Quinta Ace S can be installed individually or as part of a multi-boiler cascade or rig system, for flexible design and reliable high quality performance. The Quinta Ace S has a gross seasonal efficiency of up to 97.3% for reduced energy consumption and a low NOx from 19mg/kWh that minimises the impact on the environment. Featuring a lightweight stainless steel heat exchanger and Bluejet burner for reliable heat transfer, the Quinta Ace S comes with the latest control board and a state of the art HMI, offering improved control options.

The Quinta Ace S is programmable to work with solar thermal, biomass, buffer tanks and heat pump hybrid control systems for an energy efficient solution.
