I second this (as a hobby project). The Arduino starter/exp kit. contains all
necesarry components (a relay and PTC). The relay can switch 5A IIRC but
since I only have to short my thermostat this is not a problem.
Spaceheaters require a heavier relay. Building this is a the combination
of 2 examples (CIRC10 and CIRC11 from
http://ardx.org/src//guide/2/ARDX-EG-OOML-DD.pdf).
