Heat may be supplied by a Takagi instant hot water maker if coupled to an Ergomax tank.

The combination helps make a Takagi more like a conventional boiler and the Ergomax can create hot water for each apartment.
I am less enthusiastic about a Takagi providing just heat, as the load and water content in the loop is too small for stability. If you insist on just using a boiler for heat, I'd prefer a boiler with more water content as it is more forgiving of service.
