We've got a multi-storey house in northern Sydney (near Hornsby), mostly clad in cedar weatherboards. It can be difficult to heat in the winter, and cool on hot sunny days. In addition, we'd like to reduce our energy bills.
Can anyone recommend someone or a firm who could come around and offer independent advice on:
1. Insulating the floor/walls/ceiling more effectively
2. Heating/cooling options
3. Relocating the gas water heater, or the viability of adding a new water heater
4. Solar power
Essentially we're looking for solutions and their estimated cost and benefit.
