One Pipe System Connecting to Oil Fired Centeral Heating

[mgm2009]

Have one pipe heating system using solid fuel installed in a bunglow and was thinking about connecting oil fired central heating just wondering would this be a big job
Would I tee the flow from oil into positive side of pump or just tee in flow of existing system
Thanks for help in advance.
