Compensated Boiler Control

Hi, I have just started learning how to use Arduino. I am doing a project on compensated boiler control using outside and inside temperature but can't seem to find anything on it. I have seen some projects for boiler control but nothing like this. Could anyone point me in the right direction where to find anything on this?

Hmm.. I can believe you cannot find anything. Did you try e.g. on Google? I think, there is plenty of regulators on web that are using the MCUs like Arduino uses also so yes, the Arduino is feasible.
I have such device made myself based on ATmega1284P and Arduino system. Why 1284P? It is simple the biggest RAM from ATmega family and additional I/Os.
