Reply to comment by hijinks in Replacing 120v thermostat by WeaknessNegative392

Is that something I can put in myself? Or do I need to call in a professional. And would it get wired at the thermostat end or on the furnace end and have to run new wires the whole length of the run?

It's a fairly simple thing to do, if you're comfortable working with electricity and have basic tools (like a multimeter).

I would install it at the boiler and use the existing wires, making sure to label them as 24V on the stat end.
