We just bought a house with radiant floor heat and we have this ancient control unit for our combi boiler, and we’d like to install a nest thermostat. We have no idea where to begin. When I google anything regarding this unit and combi boilers in particular, everything is based in the UK. I live in the northeast United States. I noticed in the UK, nest thermostats have a thing called a heatlink that is connected to the boiler. Do we need something like that? Is there another way?
