Theta dual service
How dual service works
Theta dual service means using the available hot water from one of our water heaters for both domestic hot water (DHW) and
heating. Dual service can be used in combination with a BFC Cyclone, SGE or SGS system. This is a perfect system for locations
where a lot of domestic hot water and a little bit of heating is requested.
The Theta dual service system for heating consists of a plate heat exchanger with a primary DHW pump, a three-way mixing
valve, a temperature sensor with clip, the control and the required connection materials. The intelligent control uses the available
hot water very efficiently to meet the heating demand from one system without compromising comfort levels.
The central heating set point can be programmed at 70ºC, for example, for a normal radiator circuit for 70/50ºC. Or it can be
programmed at 40ºC for an under floor heating circuit for 40/30ºC.
The master will control the DHW pump and three way mixing valve to reach the programmed set point. By reducing the speed of
the DHW pump with a maximum of 50% and using the three way mixing valve to mix the return water with the water from the
water heater, a stable heating supply temperature will be reached.
By modulating the DHW pump and controlling the three way mixing valve, the heating capacity can be reduced to a minimum,
completely adapted to the actual heating demand. Moreover the mixing with the colder return water contributes to the total
efficiency of the water heater.
Thanks to the intelligent Dual service control the DHW set point can be set independently from the heating set point.

Application examples
Camp site
Theta dual service can be used on camp sites for warming the sanitary water heating the shower and toilet building. In this
case, there is a large demand for hot water and a smaller demand for heating.
The combination with a condensing gas-fired water heater BFC Cyclone makes the installation compact and simple, in which
low temperature heating, such as under floor heating, is the most ideal solution. Combined with a solar water heater SGE
or SGS, this installation becomes even more environmentally friendly because solar energy can be used for both hot water
and heating.
Sports facilities
At the majority of sporting installations there is a large demand for domestic hot water for the showers and wash basins, and
a relatively small demand for heating. In these applications the buffered energy in the BFC Cyclone, SGE or SGS can be used to
heat the shower and toilet building. Combined with a SGE or SGS the installation becomes even more environmentally friendly.

Benefits
Benefits for the installer
The application of dual service on a BFC Cyclone, SGE or SGS means both the domestic hot water and the heating demand can
be fulfilled with one installation. The installation only needs one flue outlet, one water connection and one gas connection.
Moreover, the entire installation is controlled by one intelligent controller. Service and maintenance are very easy for the
installer; just one installation for both hot water and heating.
A.O. Smith is an advocate of total system solutions. The renewable elements are delivered as an integrated system for optimum
system efficiency. By delivery and commissioning by A.O. Smith, the optimum functionality and efficiency of the system are
guaranteed. Simplicity, ease of use and a one-stop shop for your entire installation; these are the strengths of A.O. Smith.
Benefits for the user
By using Theta dual service combined with a condensing BFC Cyclone or solar water heaters SGE or SGS, it is very easy to use
the available hot water for heating adjacent spaces. This makes this system very compact whilst maintaining comfort levels.
And this solution saves the capital investment of buying a separate boiler.
The installer can buy the entire installation from one supplier and it is controlled by one intelligent controller. The installation
can perfectly be configured according to the individuals’ demands and needs.
The Remote Display (option for SGE and SGS) shows actual solar contribution and temperatures in your solar system. With use of
the BMS interface you can extract several data from the appliance: SGE, SGS or BFC. This data can be converted to your Building
Management Software.
