On one side of the ThermoBar 65 ECO there is a socket. This is where you connect the 24-volt low-voltage cable with the flat-pin plug to the transformer. From the transformer, you connect a two-metre, 230-volt cable. The cable has a regular plug that you connect with a regular wall socket.
Everything you need is included in the price:
1 water trough, 65 litres.
1 low-voltage cable, 2 metres, 24 volt, with flat-pin plug.
1 transformer, with a two-metre cable, 230 volt, and regular plug.
