The ELWA Hotrun electric instantaneous water heaters are designed for both point of use (most
efficient and lowest water and energy consumption) and multipoint applications, such as hand
wash basin/shower/kitchen sink(s), in fact all places where instant hot water is required.
The heating of the water is started instantly by opening a tap or valve connected to the hot water
outlet.
The outlet water temperature depends on the following factors:
- The flow rate through the HOTRUN (can be controlled by a flow restrictor on the cold water inlet side)
or the incoming flow into the Hotrun can be restricted by a flow regulating ball-valve.
- How far the hot water tap is actually opened
- The temperature of incoming cold water
- The mixing of hot- and cold water
When closing the hot water tap or when the flow drops below a minimum flow rate the heating
will be stopped automatically. The performance of the Hotrun depends on its electrical capacity
(kWatt rating) and also depends on the Voltage of the power supply.
A temperature rise of 25°C can be expected with the following (variable) flow rates:

The cold inlet water temperature effects the performance of the water heater, the higher the inlet water
temperature, the more flow can be expected from the Hotrun water heater.
A pressure of 90kPa is the minimum required for correct operation.
Mounting instructions
The screws and plugs are supplied with the unit.
1.
Mark the position of the plugs or screws according to the positional template.
2.
Mount the unit using 2 screws for the straight bracket.
3.
Fit the top screws allowing it to protrude approximately 2-3 mm. Slide the bracket onto the
protruding screws and ensure that it is secured without movement.
4.
Fit the last securing screw between the hot- and cold water connection.
