I have a heating system that has a separate "smart" heater in each room, each controlled with a separate thermostat (a simple one, like Honeywell T410A1013). What I would like to do is to convert to a single point of control - a single thermostat controlling all heaters.
Short of completely re-wiring the heaters, are there any reasonably affordable options to replace the existing thermostats with some kind of wireless "receivers" that would be controlled from a single device (fancy stuff like controlling via the Internet is not required)?
UPDATE: Just to be clear, I still want to have the part with the thermometer in every room, just like it is now. What I would like to change is the need to set the target temperature in each room separately. I did not mean that I would want to have a single thermometer sensor for the entire house.
