This is the most simple type of system with just a single tank (or tank group), which serves as both a solar and standby tank. This system is recommended for the redevelopment of small-scale systems where no existing DHW tanks can be used. The standard systems available differ from one another with respect to the presence of stratification and in the type of additional water heating (auxiliary heating or an electric heating element in the tank).
