    Hi,

    We have a modern gas boiler heating the radiators and an electric hot water tank. Both use those old school radial thermostats where there's a pin/slot for every 30 minutes. The radial rotates then on a timer.

    Could we avail of Nest with this configuration?

    Thanks

    The above configuration sounds fine. The Nest thermostat is compatible with the majority of heating systems. Generally there are two main reasons why a heating system may be incompatible:

    1) The system requires high-current switching.

    While most heating systems are high voltage (usually 230 V), they usually only use a little bit of current at a time (up to 3 A). However, some systems that are high voltage use a higher current (sometimes as high as 16 A or more) – for example, electric radiators or electric underfloor systems. Thermostats are designed to handle either low current or high current. The Nest Thermostat only supports low-current systems, as they are by far the most common. For instance, high-current underfloor and electric radiator systems are common in France, especially in apartment buildings.

    2) The system requires a proprietary thermostat.

    Proprietary systems only work with thermostats made by their manufacturer, since they communicate using a private protocol.

    You can find further information here. Hope this helps.
