Has anyone ever tried, successfully or not, to build a residential boiler control unit using the Arduino platform? I am considering creating a unit that is more accurate and predictive for thermostat functions. For example, the unit would call for heat when needed, but predict if the target temp can be obtained by a single boiler cycle and the residual heat that cycle creates. So instead of kicking back in when the low limit is reached on the pressuretrol, just leave the system off and let the radiators finish radiating. Even if the target temp hasn't been obtained yet. Something far more advanced than just schedule and programming like most current wifi thermostats.
I know there are some high end units and commercial controllers that let you do things like this, but I can't find anything for residential installations. Thus, the nerd in me has emerged.
