US Boiler Gas adaptive technology

Available in heating and combi models, the all-new Alta offers next-generation gas adaptive technology, providing no-touch 5-minute startup, automatic self-calibration, and sensorless outdoor reset. A simple switch converts the Alta from gas to LP (no kits or tools required). Combi models offer a virtually instantaneous DHW response, selectable comfort/recirculation modes, and include an AltaFastPipe (primary/secondary manifold).
