My house has three hydronic heatin loops; two are shaped like a ladder. The baseboard radiators are plumbed with type M copper pipe.
I'm thinking about installing thermostatic radiator valves on the 'rungs' of the ladder; one loop will be left open.
- Will this cause excess pressure in the system, causing pipes to leak?
- Will this cause the pump to fail earlier?
- Any other concerns with doing this?
I'm curious as to why this isn't done more often, as the valves seem much cheaper than zone valves.
