Wi fi thermostat

I have a oil fired hot water baseboard system with two zone valves.
My current t star is only two wire and I can get a new three or four wire into the basement.
I purchased a Sensi t stat and can wire it at the t stat however how do I wire the c wire on the furnace.
Any help will be appreciated.
Thanks
Jack

Most often there’s a C at the heating unit. If you post a pic of the control (where the stat wire connects to your system) you’ll get a fast answer0

Ahh zone valves—- you have a transformer or a “control” like the Taco ZVC to power the zone valves? You must have a c somewhere to grab if you have zone valves0

The common would be where the two zone vale motors connect to the common of the transformer ... Before you start and add a common wire to the thermostat add a fuse to protect the power source , a 3 amp fuse would be fine . To spade terminals and a 3 amp car fuse would work fine

Thanks guys . I'll be back up at the house this week. i'll look for the C terminal at the furnace or zone value. Big Ed I'm assuming a 3 amp inline fuse holder will work on the new c line to the wi fi thermostat ?0
