Yes absolutely you can heat both your pool and home with a single solar thermal system. You would require our SWH class system which comes with domestic hot water tank and second heat exchanger inside that tank. You would use the solar tank as your domestic hot water heater and plumb a circuit from second heat exchanger to both hydronic home heating distribution source (in floor, forced air, radiators) as well as to a pool heat exchanger. In summer, your system would be heating pool, and in winter it would be heating home whilst producing free hot water year-round
