Condensing High Efficiency Water Heaters

instano innovo combi A_0_0

For many years now, A.O. Smith has understood the enormous added value of condensing gas water heaters. For this reason, A.O. Smith began the development of energy-efficient condensing hot water heaters at an early stage. The first gas-fired high-efficiency water heater, the BFC Cyclone, was launched back in 1998. The introduction of Innovo and Instano has allowed A.O. Smith to offer an even more complete condensing range in a way that provides the ideal solution to every situation.

While the existing condensing BFC Cyclone, Twister, SGE and SGS are suitable for mid-range to large-scale use, the new Innovo and Instano are perfect for small to medium-sized applications. In addition, these energy-saving products all come with an A-label.


The Innovo range consists of 9 condensing sealed gas water heaters with a capacity ranging from 11.3 to 35.0 kW and a volume of 160 to 380 litres. A load profile between XL and XXL can be attained depending on the appliance, while the ErP efficiency can be increased from 90 to 94%. The entire range has a maximum temperature setting of 85°C, and with a NOx output of under 29 mg/kWh, it complies perfectly with the strictest European guidelines.


The Instano range consists of three instantaneous water heaters with a capacity of 27.0 kW to 60.9 kW. This appliance can meet a load profile of XL to XXL and has an ErP efficiency of 88% to 92%. The compact dimensions and low weight make it the perfect hot water solution for application in larger households.

In anticipation of stricter ErP guidelines, A.O. Smith has a complete range of condensing high-efficiency water heaters in order to serve the market in the best possible way.
