Can I use Radiator thermostats on a manifold instead of the radiator?
I have a house with two floors and heating system with radiators and wet underfloor heating. It's connected to a combi boiler. The upper floor has 5 radiators, all connected to a manifold which is located under the boiler.
The ground floor has two more radiators, again connected to a manifold on the ground floor, and I have another manifold for the UFH there as well.
My problem is that the radiators have no thermostatic valves, just regular ones, but the manifolds have. Can I use the Wiser radiator thermostats on the manifolds? Then obviously the call for heat should come from a room thermostat instead of the radiator thermostats. Is it possible?
So what I'm thinking:
1) a hub where the boiler is
2) as many radiator thermostats as the number of radiators I want to control, all placed on the manifold on the upper floor, right under the boiler
3) room thermostats for each radiator thermostat mentioned above to call for heat
4) on the ground floor again, radiator thermostats placed on the manifold instead of the radiators, and room thermostats as well for each
5) maybe an UFH controller, also on the ground floor if I want to control those separately (5 circuits, but max 2 zones)
There are no zone valves, just the thermostatic valves on the manifolds, and a pump for the UFH, currently running 0-24, as it's just plugged into a wall socket.
