OFCH + Stove with Backboiler ->Pumps????

Hi All I have just moved in to an old house and fitted a new stove with a backboiler, 15KW to water + 2KW to room. Burning wood so not likely to get the full 15KW.

Hi All
I have just moved in to an old house and fitted a new stove with a backboiler, 15KW to water + 2KW to room. Burning wood so not likely to get the full 15KW. This works great and gives piping hot water to the tank and all upstairs rads with gravity circulation.
There is also an oil boiler in the shed with a pump. Problem is, when I turn on the oil with the pump it reverses the flow through the back boiler.
I understand I Will need a pump with a thermostat to circulate to the downstairs rads with just the stove on.
Questions are:
Should I fit a one-way valve on the circuit to the back boiler?
What will happen if both the pumps are running at the same time?
Anybody have any suggestions?

Thanks in advance
