Electrical question

[mightysinger]

We have recently bought a new sand filter, salt water sanitiser and a 6kw titanium heater. I understand we have to have a qualified electrician to install these items, does anyone know roughly how much this would cost?. Also, the salt water sanitiser came with no pipes or fixings, does anyone know what we need to connect this with the filter and heater? the inlet and outlet are quite big with no thread on it and the instructions are a very vague picture. Any help would be great as we are new to all this and have all the equipment but no knowledge to install it all. Thank you very much.
