Morning, I am thinking about replacing the existing C/H controls with a Hive system. on the S/Fix site it says suitable for Gas and LPG. however my boiler is an oil fired combi(worcester 12/18) Is there any reason that it will not be suitable for this? I don't think it should be an issue, but would welcome any views. Also, we have a very poor mobile signal.. sometimes non-existant ,but have good broadband .Is this a problem? can it be operated using the internet rather than by phone?
