I have just installed EQ-Max a German system, works great and better than any of these so called automated systems. This system allows you to change your Danfoss (or other makes) automated valves for their wireless ones, install separate thermostats in each room, install wireless window contacts that tell the system when someone has opened a window in a room and shut down the radiators in that room. The whole system is linked to a Network box plugged into the router and a PC (the PC does not need to be left on) I can control each room from my Iphone, my wifes iphone or from any PC in the world. When one of the kids is away at a friends I can simply switch off that rooms radiators NOT expensive! Each typical room costs £68 for 1 valve, 1 Thermostat and 1 Window sensor. The Network LAN gateway box is just £43 to control the whole system. Although the winter has been mild I am saving up to 40% a month on Gas use.
