Can I Split Thermostat Wire???

Jambruins

I installed a pellet stove and hooked it up to my thermostat that used to be hooked up to my boiler (I ran a new wire for the pellet stove). The wire from the boiler is still in the wall so I can disconnect the pellet stove wire and reconnect my boiler wire if I want.

However, I would like to install a separate thermostat for the boiler. My thought is to run new wire from my new thermostat, cut the wire from my boiler to the existing thermostat and tie all three wires together?

The old thermostat will not have the wire from the boiler hooked up. I would like to have the wire there incase I want to run the boiler from the existing thermostat in the future.

Let me know if you don't understand what I am asking and I will try to explain it better. Thanks.

wouldnt they all have to be calling for heat ? thats the purpose of zone valves ,create zones and each one has own thermostat .. if you have multiple thermostats on same line one calls for heat andother doesnt , then it wont make the nessarry loop to operate the circulator or zone valve

Only the new thermostat will have the wire from the boiler hooked up to it. The other wire will be behind the old thermostat but not hooked up to it.

you mean just hiding it in wall ? then hooking up when you need to in future ? and eliminating the one now ? its not hooked up to anything but the old thermostat .it would just be a dead wire .

I currently have a wire from my boiler to a thermostat. I disconnected the wire from the thermostat. I ran a new wire from my pellet stove to the thermostat so my thermostat controls the pelllets stove. I am going to install a new thermostat in another room and hook that up to my boiler. I would like to leave the wire that runs to the existing thermostat in the wall (disconnect from the thermostat) so if I want to in the future I can hook my boiler up to the existing thermostat. Can I install my new thermostat and just run a new wire from my new thermostat and hook it to the existing wire (like a junction box) instead of running all the way to the boiler. Thanks.

yes be sure connections are tight and serviceable.
