We currently have an "old fashioned" system with a Vaillant EcoTec 637 (Way oversized), a timer for the radiators (with room stat in hall) and vented HW cylinder (with tank on/off stat) + a programmable stat for the UFH
In discussions with the Vaillant technical people I think the solutions they have suggested (VRC720 + VR92 + VR71 + VR10s) is correct but I have a simple question to start with that's more to do with layout than the inevitable follow up questions about how to control it all
We have a 2.3KW radiator in the hall and UFH in the Dining room and Kitchen which are all in an open plan area. Currently the radiator thermostat is in the hall (near the dining room) and the UFH thermostat is between the dining room and the kitchen (not near the hall). It always feels like the thermostats are fighting each other and either the other rooms are too cold as the UFH is causing the radiator stat to turn off or the UFH is turning off too early because the hall is heating up the dining room (happens less often)
My question is with the new system we will still have two room thermostats for load compensation (one for radiators one for UFH) so where would it be best to place each one or is it not an issue as the weather and load compensation plus the modulation of the boiler enough to "balance" the system?
