## Long description

KOSPEL SB-300 Termo Solar standing storage hot water cylinder is designed for domestic hot water (C.W.U.) systems in homes and small buildings. The vertical tank stores heated water and features two internal heat exchangers that enable connection to solar thermal collectors and an auxiliary heat source. Constructed for combination use, the cylinder supports integration of renewable solar heating with conventional boilers to provide continuous hot water supply while optimizing energy use.
Advantages
The SB-300 Termo Solar offers a dual-exchanger layout that separates solar circuit heat transfer from auxiliary heating, reducing mixing and improving overall system efficiency. Its vertical standing design eases installation in utility rooms with limited floor area. The internal configuration supports stratification and effective temperature layering for improved draw-off performance and minimized standby losses. Materials and workmanship are tuned for domestic hot water use and reliable long-term operation.
Suitable for
Residential domestic hot water systems combining solar thermal collectors and a backup boiler
Small apartment buildings or multi-family units requiring centralized hot water storage
Renovation projects where integration of renewable heat sources is planned
Key specifications
Standing vertical storage cylinder with internal dual heat exchangers
Designed capacity around 300 liters suitable for household hot water needs
One exchanger dedicated to solar thermal input, second exchanger for auxiliary heater or boiler
Thermal stratification support for efficient hot water draw-off

How to use
Install the KOSPEL SB-300 Termo Solar according to manufacturer installation guidelines and local plumbing codes, ensuring correct hydraulic connections for the solar loop and the auxiliary heat source. Fill and pressure-test the system before commissioning. Set the temperature controls on the auxiliary source and any controller for the solar circuit to achieve the required domestic hot water temperature while maintaining safe anti-scald limits. Perform initial commissioning to purge air from heat exchangers and check all safety devices and expansion vessels in the system.
Usage recommendations
For reliable operation, schedule regular inspections of the tank, heat exchangers and connections. Maintain the solar circuit with appropriate antifreeze and periodic flushing according to the collector manufacturer’s guidance. Verify safety valves, thermostats and sacrificial anodes (if fitted) at recommended service intervals to preserve efficiency and prolong service life.
