The (new build) house we have just bought has underfloor heating downstairs and a conventional TRV/thermostat arrangement upstairs; I guess this setup is quite common. However, the thermostat (and the uncontrolled radiator) are on the galleried landing, which receives a significant amount of heat from the UFH in the hall below. Therefore there is a tendency for the bedrooms to go cold when the UFH is running, unless the thermostat is turned up.
Is this a sensible arrangement? I would have thought the thermostat and uncontrolled radiator ought to be in a zone isolated from the influence of the UFH.
