A recirculating pump comes to mind. Since I know nothing about heating systems would you like me to kick this over to a heating expert? Cheers, Tom

More info needed... like how much water(heat), flow, you want (need)?. what is the pressure lost through the piping, the spec on the pex hose

To actually calculate what you really need, might take more data than you could ever come by. I would pick up a pump meant for a small hot water system and hope for the best. Where did you get the boiler? Ask there about a pump. Whatever you buy, make sure it can handle hot water.
