Cool project.
Speaking of newish natural gas (CH4) heaters, they all should have modulating thermostat capability with OpenTherm/eBus or other protocol. Combined with a thermostat with outdoor temperature sensor system efficiency is increased a few percent and that should help offset thermostat and installation costs. In the end you have more efficient modern heating system.
Same should apply for heat pump systems.
- steelegbr 1y agoOpenTherm is a cool idea but even new installations aren't always wired for it. When installing a new smart thermostat I found the installation has been wired as S Plan with the few cables running between the boiler location and valves location already consumed. Makes the job much bigger if you're not prepared for it.
- buccal 1y agoThere are many wireless OpenTherm thermostats. Wired is better but is not required for modern thermostats.
