I know in Sydney if you have no gas, it would cost you $125 for AGL to run a line into your property.
Then its up to what the plumber charges to run the line from there to your desired location.
Ive read that heat pumps are absolutely terrible and to avoid them at all costs.
I've also got an Electric Instant in my IP.
It needs 3 phase power and its REALLY REALLY weak.
It will heat up enough water for ONE user only at any time.
