model no is SX20 MFFICE and serial no: 970102077
I need the loading capacity hourly

The Ariston Eurocombi A/23 MFFI is rated 23.1kW
The Ariston Eurocombi A/27 MFFI is rated 27.3kW

If your boiler is not being used then the hourly load will be zero otherwise it will be the proportion of an hour used (0.3 - 0.5 - 0.75 etc) multiplied by the rating of your specific appliance.

Both boilers have an efficiency rating of about 78%
