Why Upgrade Your Heating & Cooling?
Modern heat pump technology is 3-4x more efficient than traditional heating methods. Here's why it makes sense for Perth homes.
Heat pumps use 3-4x less energy than resistive heaters (COP 3-4). Savings vary by system and usage.
Electric heat pumps produce far fewer emissions than gas heating, especially with solar.
Run your heating and cooling from your solar panels for near-zero running costs.
Reverse cycle systems heat in winter and cool in summer - one system does both.

Energy-Saving Tips
Get the most from your heating and cooling system.
Run your heating/cooling when solar is generating to minimize costs.
Each degree of cooling/heating costs about 10% more. Aim for 24-26°C in summer, 18-20°C in winter.
Only heat/cool the rooms you're using. Close doors to unused areas.
Clean filters monthly. Service your AC annually for best efficiency.
Frequently Asked Questions
Common questions about efficient heating and cooling in Perth.
Yes. Heat pumps use 1/3 to 1/4 the electricity of traditional electric hot water. In Perth's climate, they work efficiently year-round. With STC rebates reducing the upfront cost, payback is typically 3-5 years.
Reverse cycle split systems (Daikin, Mitsubishi, Fujitsu) are the most efficient choice. They provide cooling in summer and heating in winter. Look for 4-5 star energy ratings and ensure the system is correctly sized for your room.
For most Perth households, switching to efficient electric (heat pumps, reverse cycle) makes sense. Gas prices are rising while electricity from solar is essentially free. Modern heat pumps are 3-4x more efficient than gas.
Yes! This is one of the best uses for solar panels. Air conditioning demand peaks during the day when solar generation is highest. Time your heavy cooling to solar hours for near-zero running costs.
As a rough guide: small bedroom 2-2.5kW, medium room 3-3.5kW, large living area 5-7kW. Proper sizing depends on room size, insulation, windows, and orientation. Oversized units waste energy; undersized units struggle.
