I have an underfloor heating system fed by a Thermal store.
Temperature is limited by the thermostat on the Thermal Store to 60C
Water is pumped on Return circuit from distribution manifolds for the UFH
To aid in boiler efficiency and solving some other issues, I intend to add a 28mm Thermostatic Mixing valve .... The first picture represents position a 'as is'
The 2nd picture is Option 1 ... preferred as much easier to add to the existing layout, pump position as is, i.e. pumping the return.
The 3rd picture is Option 2 ... moving pumping out the flow of 'mixed water' rather than on return.
Any reason that Opt 1 or 2 should be used .... or perhaps easier Q (for me) any reason I can't use Option 1
