Was a question about older equipment not having a c terminal only r and w, if your planing on using a thermostat that requires a c and a second transformer as a power source to get your c (common wire) then please be careful, if you mix phases on you 120 volt power source (phase a one and phase b second) between the heating appliance and the new thermostat you will find a lot of factory smoke leaving the transformer(s),Instead power your thermostat with the second transformer and use that power to switch a relay coil, then use the dry normally open contacts of the relay to make the circuit between r and w of the heating appliance to isolate the two power sources yes it costs a relay but thats much cheaper then a mistake and finding you now have equipment damage.
