In some situations, when a heat pump is replacing a solar heating system, the pipework is available to
be used next to the house but there is no way of adding a new electrical circuit to the pool equipment.
With the use of an additional temperature sensor, you can use the in-built flow switch to activate the
heating. Allowing you to use the existing solar pump and to install the heater closer to the switch
board.
1. In may be impractical to get a new power cable from the house switch board to the pool equipment area
due to finished flooring etc., in this case It may be possible to use the existing pipework which connects
to the house and install a power cable from there.
2. An external thermostat controller can initiate the existing circulation pump, thus running the heat pump
through the flow switch for full temperature control.
Please speak to your installer for more information.
3. No additional wiring to the heat pump is needed internally
4. Timers are set on the external thermostatic controller
5. Set heat pump a couple of degrees above the set point temperature of the external temperature controller.
