Tado with Viessmann 100-W
I have a mixed tado system (three zones with wired stats, trvs, strvs, and a wireless stat) that works well with my ancient Worcester Bosch boiler. The Megaflo hot water cylinder is heated via a timer switch on a fourth zone. I have no idea what controls the temperature of the DHW. I adjust the boiler temperature from time to time as a form of manual weather compensation.
I am considering replacing the boiler with a Viessmann 100-W with weather compensation so I don't have to do it manually. It will also manage the hot water. Will it be that simple - setting the weather compensation curve on the boiler - or might there be more to it?

Having now replaced my boiler, I can answer my own question:
Yes, it's as simple as that. The boiler makes available to tado heating system water at (low - 35 deg. today) temperatures appropriate to the outside conditions and also tops up the DHW as it thinks fit to maintain the temperature I set in the ViCare app. tado does its thing via the three zone valves and I could not be happier. 😊
