Replacing 9 old in-floor heating 2 wire thermostats
We have in-floor heating with 9 zones. Each zone is controlled by an in-room older thermostat with no electricity or batteries, ie a simple basic thermostat where you set the desired temp by hand ie a simple on/off switch basically that trigger a basement based loop valve to open or close.
I’d like to replace this with something more modern and accurate (as I find the temp settings often imprecise) but do not want to bring a wire to each of the 9 thermostats (and cut drywall, remud and tape & paint afterwards x 9) as most modern thermostats require a 3 wire feed ie one with electricity.
Suggested options here ie likely best battery based thermostat system, or perhaps wireless from one central area?
