I've successfully plumbed in my Tarm Solo 40 with storage into my heating system. I'm now in the process of hooking an oil fired boiler into it as a backup. I'm wondering if there is any need to add a circulator into the output of the oil boiler or is the circulator for the zone sufficient. Here is a crude diagram of the supply side plumbing with the circulator in question marked with ???
