Recommended boilers for Tado
So I've really invested in Tado as I think it works great for our needs and allows us to make best use of controlling the 3 heating zones in our house while keeping the heating off in the various rooms we don't routinely use. It is currently teamed up with a Vaillant Ecotec 428; it seems a pretty robust boiler but and is maintained yearly, though it is now 12 years old, so starting to enter the bracket where risk of failure is ever increasing.
While I hope it lasts for a while yet, I want to be at least partially prepared for if/when it does die on us. Does anyone therefore have any good recommendations for boilers that work well with the Tado ecosystem? Key considerations are efficiency, noise, and of course integration with Tado, current boiler is 28kw.
