2.9System 9: Greenstar Heating Boiler in a single zone system with solar thermal DHW and boiler backup

Summary:

Single boiler with primary/secondary piping configuration supplying one heating zone. Outdoor reset with FW200 controller with built-in room sensor mounted in the living space for room feedback.

Use this design where System 4 cannot be used due to too great a system pressure drop. Primary/secondary piping is also required for radiant floor and panel radiator applica- tions.

Primary/secondary piping isolates the system flow from the boiler flow and prevents the system from influencing boiler performance.

Solar thermal provides renewable energy to heat DHW year round, and if sized properly reduce energy consumption significantly. Bosch offers plug and play components

that are designed to work together with a boiler backup system. Bosch solar thermal systems are qualified for government and utility incentives reducing the upfront investment cost significantly. Bosch solar thermal collectors work even in the winter and under cloudy skies preheating water, and reducing boiler run time and burner starts.

In detail:

The FW200 is an outdoor temperature based controller with room temperature influence. The controller adjusts the heating curve (boiler supply temperature) according to outdoor temperature. When the FW200 is wall mounted as a room sensor, it uses room temperature to adjust the heating curve and modify boiler supply temperature ac- cordingly.

FW200 provides warm weather shutdown.

The control of the solar thermal system is integrated with the FW200 boiler control, and reduces boiler run time and burner starts significantly compared to independent systems. The solar pump will run whenever the collectors are 16°F (9°C) warmer than the bottom of the solar tank.

For temperature sensitive radiant floor applications install a thermostatic tempering valve for overheat protection.

Required components:

Greenstar heating boiler.

FW200 controller in the room.

Primary/secondary piping and system pump.

Thermostatic mixing vavle (optional - overheat protection for temperature sensitive floors).

ISM2.

DHW solar tank with 2 coils.

Bosch solar thermal system complete.

Tank loading pump of sufficient capacity.

Additional instructions:

See manufacturer’s installation and operating instructions.

The Bosch Greenstar boiler and ISM2 offer many different solar thermal applications including space heating sup- port and pool heating. Please consult the installation and operating instructions for details.
