I know Daikin makes one for the the European market, but I can’t find a similar product that is available here.

    Joseph,
    The equipment you are talking about appears to be a Daikin Altherma that is programmed to coordinate performance with a tankless gas boiler; more information is here:
    http://www.daikin.co.uk/minisite/hybridheatpump/index.jsp

    In the warmer sections of the U.S., it is common for HVAC contractors to install an air-source heat pump for space heating, for use when outdoor air temperatures are mild, and to also install a gas furnace that comes on when the outdoor temperature drops to about 25 degrees F.

    These days, now that cold-climate heat pumps have been invented, there are fewer reasons to install these two types of heating systems.

    Daikin does sell an air-source hydronic heat pump here. Someone good with controls could wire up controls for that with any boiler to do what you want. But you might be fine with just the air-source heat pump.
