Great, there is a chance to find this using celsius scale for temperatures? Thanks

thanks for the presentation. I'm a newb, but what I conclude is, have combi boiler temp set as low as tolerable for max efficiency?

Question for Viessmann instructor: I have a Viessmann Vitodens 100-w B1HE 120 BTU installed and thermostat controlled for each zone. Can you please provide some additional configuration/setup information on how I can achieve the efficiency levels you describe in the video at approx. 23:20 (slide 21). Thank you for your help.

When a boiler such as the Vitocrossal CU3A is piped only primary as a replacement for an old cast iron boiler on a converted old gravity system, does the circulator have to run constantly for the outdoor reset to operate properly?

It's very naff Viessmann talking about boiler efficiency when they don't design efficient boilers !
Anyway, my Viessmann might be the last boiler I buy.
