Hydropower

All it takes to fire up a Therm water heater, is the opening of a tap. Ignition is achieved with the help of a battery or the Bosch Hydro Power ignition system making use of the most clean and economical energy source possible. The force of the water is responsible for the ignition of the burner.

The Multi-point Hot Water System

With a multi-point hot water system, all hot water points are supplied by a single water heater. The amount and temperature of the water used can be individually controlled at each tap unit. This type of arrangement is best used where the piping runs to the various hot water outlets are not excessively long.

The Single-point Hot Water System

In this case, separate gas instantaneous water heaters are installed directly at each hot water point – over the kitchen sink and the bath, for example. The advantage of this arrangement is the immediate availability of hot water at the point of use.
