How do I supply radiators on demand while supplying floor heat
Here is my work in progress. Since the picture I have added 3 circulator pumps for each manifold. Each lower manifold supplies the radiant floor heat.
The upper manifold supplies all the wall hung radiators to the 2nd floor bedrooms and bathrooms.
Being the indirect is up and going for DHW and on it's own heating loop, I would like the radiant and radiators all to run at 130 degrees. My question is, with the radiators having a TRV, how do I supply the radiators so the boiler isn't constantly firing to heat and circulate the water; possibly making the efficient system inefficient.
