Most hydronic heating systems that have renewable energy heat sources, such as solar thermal collectors, an air-to-water or geothermal heat pump or a biomass boiler also have an auxiliary heat source.
What would an ideal pressurized thermal storage tank for a solar combisystem look like?

Residential solar combisystems provide domestic water heating and some percentage of space heating. Although less known than domestic hot water-only systems, combisystems can be practical and efficient if properly sized and designed.
