Efficient climate control
Cut your heating and hot water bills by up to 70% with modern heat pumps and efficient air conditioning. Perfect for Perth's climate.
Annual running costs (4-person household)
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.
Heat pumps run on electricity, not gas. No combustion means no nitrogen dioxide indoors, and measurably better air quality.
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.

Get the most from your heating and cooling system.
Run your heating/cooling when solar is generating to minimise 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.

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, modelled payback is typically 3-5 years; actual results vary with hot water usage and electricity rates.
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 running on your own solar power costs a fraction of the grid rate. 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.

Heat pump hot water systems use 65–80% less electricity than resistive element systems. Here's what they cost, how they work, the best times to run them in Perth, and how they interact with solar.
Perth households replacing a gas or electric hot water system with a heat pump have several brands to choose from. Here's how Reclaim Energy, Sanden, Rheem, and Dux compare on efficiency, warranty, and fit for Perth conditions.
Perth has one of the highest evaporative cooler rates in Australia, but evap coolers stop working on humid days. Here's how the two systems compare on running costs, solar synergy, and Perth's specific climate.
Solar thermal hot water systems were the standard recommendation for Perth for decades. Heat pump hot water systems have now overtaken them on cost, reliability, and flexibility. Here's the comparison.
