I want to remove a zone from my hot water heating system. The zone has an an electric zone valve wired to my panel and to the thermostat. When set the thermostat to turn up the heat, it closes a circuit that causes the zone valve to switch on a motor that open the valve for that zone allowing heat through the piping.
On the return side of the piping, there is a manual valve. I was wondering what the process is for disconnecting a zone, draining the water from that part so I can completely remove that zone and it's piping.
Edit: I am doing this because I want to replace a line of pipe that is deteriorating and move one of the radiators. I also want to keep the other zones operational so the rest of my house has heat. During this time I will also be doing some work on the interior, so I have to remove and move some radiators and walls. That is why I want the other zones to work.
