DX buffer tank?

I'm building a geothermal HP plant to feed my infloor heat. A water to water heat pump will still need a buffer tank. Does anyone know of a buffer tank with a DX coil in it? That would save me on pump and the power to run it. 2 ton HP with 40 gallon buffer.

    @STEVEusaPA thanks, but this is the conventional way of doing it. I have parts to build my own HP and I am wondering if putting the DX coil in the tank, instead of a separate heat exchanger that is pumped to a tank, is out there. I have some that are this way for my commercial process chillers. But that is chilled, and overkill for a residential system.
