As is well known, solar power is semi-permanent self-sufficiency without additional costs if the facility is equipped with energy compared to coal, petroleum, natural gas, nuclear power, etc., in particular, there is an environment-friendly advantage.

Therefore, interest in eco-friendly houses using solar or sunlight is increasing.

However, solar system not only needs backup equipment, but also consists of various large and small parts such as heat storage tank, pump, piping, controller, heat exchanger, valve, etc., and most of these components are installed. As it is being constructed in the field, it requires not only a wide installation place, but also requires a lot of construction time and complicated system, which makes it difficult to follow-up management.

In addition, since backup facilities (boilers, heat pumps, etc.) have not been developed for solar systems, it is difficult to efficiently link with solar systems.

Among these, geothermal heat pumps are increasingly being used as high-efficiency devices, and are classified as renewable energy. However, when only geothermal heat pumps are used alone, a considerable amount of electric energy is consumed. In addition, the system configuration is similar to the solar system, and is composed of a buffer tank (a kind of heat storage tank), expansion tanks, various valves, and a heat exchanger.

Here, any device (boiler, heat pump, geothermal pump, etc.) is used as a backup facility, but there is no packaged device in which all components except the solar collector and the backup facility installed outside are compactly combined. It is pointed out as a disadvantage.

In addition, until now, solar or geothermal heat pump systems have a system in which systems are separately constructed and used, but there is no packaged product that is compactly combined into one heat storage tank.
