Have a circular pump hot water boiler for heat in my home. Our bedroom on the second floor gets a good bit warmer than the rest of the house. As I’ve heard about these TRV before I’ve been reading up on them and debating about installing one to reduce the water flow to cut back on the heat. I’ve done a good bit of plumbing and installing cast iron baseboard heat so I’m confident this is within my skill level. So besides the diameter of my threaded supply lines is there anything else I need to consider? I’ve seen a couple manufacturers and wondering about the Honeywells. These things do the job I’m hoping to get? Thanks in advance.
