Compost Furnace ~ what are the next steps? 150 150 Strawbale Studio

The Pile is complete and the components for circulating the hot water generated by the pile to heat the floor and benches of the Strawbale Studio are being designed with the advise of many:

The hot supply water from the 15′ X 25′ X 7′ Compost Pile which is 5 ft to the west of the Strawbale Studio is entering the Strawbale Studio through the wall:

I think there should be some sort of flow restriction valves on each loop to adjust flow/temp through the unequal loops if necessary . 7)  pex loops go through the floor then 8)have an inline thermometer on each loop before going 9) back to a manifold that takes the two 1/2″ pex loops back to one 1″ pipe,  10) followed by a shut off valve, then 11) the pump and 12) another shut off value, then the 1″ diameter “cold return” pex pipe exits the Strawbale Studio to circulate water through the Compost Pile.
