Energy Levels

As you go about the tasks involved in maintaining your home, consider basic tasks that can help reduce your energy consumption, which will leave both your family and the planet better off.

Up to 40% of household electrical bills are usually made up of water heating, so this is an important place to start.

Water Heating

BASIC – If your hot water cylinder is more than slightly warm to the touch, buy an insulating wrap to reduce heat loss. This could save you around $140 per year.

STEP UP – Retrofit a water heating heat pump to your existing hot water cylinder. From that day on, you could save up to 60% of your running costs compared to a standard electric storage cylinder.


Switch off all appliances at the wall rather than leaving them on stand-by. New Zealand as a country wastes $100 million per year on stand-by energy!

Make it a habit to switch off lights when you leave the room. As old bulbs die, replace the most frequently used ones with CFLs (energy saving Compact Fluorescent Lamps) BUT be sure your fittings are energy efficient too.


Install roof and floor insulation and look forward to spending the next winter in a warmer home. Insulating your home is the single most effective measure you can take to keep your home warm and to save money on energy bills. There is a lot of heat wasted if you are running a heater all winter as without insulation a large percentage of heat is lost through the walls, floor and roof. In an insulated home you can trap that heat in and either turn your heater down or off.


Problems with dampness and mould? Draught-seal windows and doors then install a proper heat recovery ventilation system which pre-heats fresh air coming from the outside or the roof space with almost 90% efficiency (using less energy than a light bulb!)
