Block off any chimneys not being used – A lot of heat is lost there. 19 Unless you have full home conditioning close the doors of the room/s being heated or cooled. Doors and windows should fit well because draughts can waste a lot of energy. Close curtains to stop heat escaping. 20 See that air- conditioner filters and condenser coils are kept clean.
1 Reverse cycle air-conditioners provide 2 to 2. 5 times as much heat as an element type heater for the same electricity consumption. 22 Zoning of a house conditioned by a ducted system can cut energy consumption to a half or even third. 23 Shade windows during summer to keep sun of the glass. 24 Don’t leave heating or cooling appliances on when rooms are unoccupied. 25 Use personal fans and ceiling fans for relief from hot weather. Fans cost much less to run than air conditioners.
26 Many air- conditioning systems operate at 22 deg (c). You will still be comfortable if you set the control for 24-25 deg (c) in summer and 18-19 deg (c) in inter and you will use a lot less electricity. 27 Leave room conditioner ” fresh air ” and ” exhaust air ” controls in the closed positions unless you want to freshen thew room air. 28 Set fan at high speed for a room conditioner to work most efficiently. 29 Evaporative coolers are very effective when installed correctly.

WATER HEATING 56 Off peak low pressure storage heaters are generally the cheapest overall. 57 Don’t allow dripping taps . Sixty drips a minutes means about 1200 litres a month drown the drain.
And you have paid for it to be heated. 58 Water restrictors and low flow shower nozzles will help to save water. 59 Insulate hot water pipes from storage heaters for at least a metre from the heater as heat can be conducted along these pipes and lost to the atmosphere. 60 Install a storage heater of 125 litres or more to run off peak tariff – which is bout half the normal rate. 61 Normally you will use less water for shower than bath. 62 Fill your electric kettle or jug from the cold tap.
