For over a year now I've been (very) slowly converting a room to be much more energy efficient by increasing insulation and airtightness. The plasterboard has been replaced with Variotherm Radiant Panels (18mm Fermacell boards with UFH pipes modelled into the board).

Now I need to connect the new manifold to supply the panels (~30-40deg C) to the existing heating system (60-80degrees C). I have the manifold but need to add a mixing valve and pump. In addition I'd like to control the setup via Cortex. Has anyone blogged, documented or had experience of setting up such a system with Idratek and Cortex?
