# Theta Dual Service

Theta Dual Service is A.O. Smith’s unique way of using hot water from a water heater for both sanitary hot water and space heating. These modules can be used in combination with a BFC Cyclone, SGE or SGS system. This is a perfect solution for locations where there is a large demand for hot water and a small demand for heating.

Due to the intelligent control, the system can utilize its storage for both hot water and heating; from one system, without compromising on comfort.
