It doesn't need to be that complicated. I would use an aquastat to protect the boiler though. You can connect the pump to it so it just shuts off the pump when the temperature drops too much.I would put a bypass at the heat exchanger also. Just 2 ball valves are all that is needed. That way you can adjust the heat load to what the boiler can handle. If you skip the bypass, I would go undersized on the heat exchanger.Another thing I would do it put it on unions so you can just pull the heat exchanger and take it inside during the winter. You can do without and just winterize it with antifreeze but just removing it should be easier.
