HOW YOUR
POWERSTREAM
WORKS
The Powerstream instantaneous water heater is designed to provide instant hot water at a fixed heating
capacity. By opening the water outlet, tap or shower the appliance flow switch activates and in turn
energizes the heating element. The neon light on the front of the appliance is illuminated whenever
heating is on.
As the water is instantly heated with a fixed power capacity, the appliance output temperature varies
depending on:
- The temperature of the mains water supply.
- The water flow rate, i.e. volume of water through the unit.
- The power consumption of the unit.
The temperature of the main water supply can vary from 5°C in winter up to about 20°C in summer,
with an average of about 12°C. The charts below show the water temperature (°C) you can expect
from the unit, operating at 9.5/10.8/12.0kW for the different flow rates (in litres/minute).
This means that with the 12.0kW unit you can shower at 39°C with a flow rate of 5 litres/minute in the
middle of winter. The Powerstream appliance is intended to supply up to two wash hand basins or one
wash hand basin and one shower application. It cannot deliver the temperature and flowrate
combination required to fill a bathtub.
This appliance must NOT be used for commercial applications or applications where
high temperatures at high flow rates are required, i.e. dishwashing or for filling
baths.
The unit includes a dual thermal cut-out (diagram 1) which is attached to the heat exchanger tube.
It will switch off the heater elements if the water flow is reduced too much and the temperature goes
above a set limit.
The first stage cut-out is cyclic and will automatically reset as the water
temperature falls. The unit will then function normally again.
The second stage cut-out when triggered needs to be reset manually inside the unit.
This cut-out will only operate in exceptional circumstances or if the product is being
used outside of its scope of suitable uses. (diagram 1)
The unit can supply two outlets – for example, a shower and a basin, or up to two basins – but water
from the unit will be shared between the outlets. This is particularly important if a unit supplies a
shower and a basin, as the basin should not be used while someone is using the shower. The unit is
NOT to be fitted to a bath or kitchen sink other than for hand-washing purposes.
