We're renovating a 30 year old home in the US and replacing three 240 volt electric baseboard heaters with new, modern heaters.
Currently, each of the three 15+ year old heaters are wired into their own "dumb" analog thermostats on the wall. We're looking at possibly replacing these with "smart" heaters like these which have an onboard thermostat, and then can be centrally controlled.
As I understand it, these new heaters should not have a thermostat in the wall; they should be connected directly to the breaker box. And I believe that currently 240 volts run from the breaker box to the thermostat in the wall and then from there to the heater. If that's correct, can I simply remove the thermostats, connect and cap the wires, and replace them with blank panels? Or would I need to run all new cable directly to the new baseboard heaters?
