It wont be connecting to your heating but interference may be an issue (when the heating chats with the remote and vice versa), as would any other devices that use those frequencies (wireless headphones, phone data wifi etc).
If its working on other platforms, it does kind of point to Zwift. And coincidently this thread popped up with a Galaxy S7 and a Direto having similar but different symptoms. Not saying its the same issue, but may be related and worth keeping an eye on.
