Termovar valve options

I've always wanted to try A Grundfos Mixmiser on my wood boiler. Seeing as it has nil for pressure drop, properly applied the sensors would watch the temperature and speed up or slow down the flow to maintain 140F return.

Currently my EKO, as many others, has a fixed 140F stat that the boiler pump wires to. Temperature falls below 140F the boiler circ stops.

Viessmann uses this same control on their basic cast iron boilers for return protection.

Simple but effective.
