The difference between the Espar and Aqua Hot is that I don't have a separate boiler fluid, it uses the same engine antifreeze.
Espar is German (?) made and was originally developed for the trucking industry. Yes, It requires antifreeze, but you can plumb that into one side of a heat exchanger and make hot water.
Performance and your comfort are going to be very dependent on the installation, especially if you are doing in-floor radiant heat (by far the most comfortable). Underfloor insulation is mandatory.
