We currently have a mixed heating system comprised of 2 boilers, an air source heat pump, a wood burning stove and range cooker. Radiators are controlled via thermostatic radiator valves. I'm a bit of a gadget fan and like the idea of a smarter heating system. Does anyone have hive / nest or smart radiator valves? What is your experience of these technologies ? Currently I'm thinking that a hybrid mix which includes smart TRVs is the way to go. My reasoning is that you tend use different zones of a house at different points in time. A timer or indeed hive / nest does not offer such zoning. E.g. In the evening I would be mostly downstairs and therefore could defer the heating of the upstairs rooms until later, kids rooms might get a preheat followed by an increase 1 hour before they go to bed (there are several playrooms so I don't see much need to heat the bedroom when they won't use it) Interestingly any modern home of 150m2 or more is meant to have multiple heating zone according to part L of the building regulations. My property is considerable larger than this but less sophisticated controls. I think smart TRVs are a simple way to achieve such zones. Does anyone have smart controls. I'm not that bothered about internet connectivity in fact that could be seen as a week point. If I was to go down that route I would probably use a relay switch from a low voltage input to a mains voltage device, using my own server to achieve this; rather than trusting security to others.
