second pump system?

hav recently installed a wood burning boiler stove , the system with adition of 2 gate valves to route and controle waterflow works a treat -lookin forward to a minute gas bill , as the system retains use of the gas boiler i have to turn the boiler stat up again to QUICKLY heat the hot cylinder and set controles according - its like running a powerstation swichin from boiler to stove with valves and controles to swich over . to simplyfy things and make it unnesasary to run the powwerstation i want ad another pump near the stove wich will run only the heating circuit leaving the old pump/gas boiler to sort the bath water. the 3 way port is a manual hand turner as the motor dont work . is this a doable thing to run 2 separate circuits. cheers lee jcb mecanic.
