BEopt cannot model multiple pieces of equipment that both provide heating (or cooling). Since BEopt assumes that the mini-split will be providing both, it cannot be combined with a boiler. If you have a mini-split selected and then try to select a boiler (or vice versa), it will automatically deselect the other option to prevent two pieces of equipment providing heating.
That said, you could use BEopt to do two separate runs -- one with a mini-split and one with a boiler/AC -- and then combine the results using the cooling energy from the mini-split run and the heating energy from the boiler run.
