Last issue we looked at space heating, this issue we will look at the other big part of your energy bill – water heating.
Heating water takes a lot of energy. Did you know the average hot water cylinder contains as much energy as 10kgs of TNT?
· Check your water temperature; 55oC at the tap is ideal.
· If your cylinder is warm to the touch – put a wrap on it, and don't for get to insulate those hot pipes (the first 2-3 meters from the cylinder are the most important).
· Fix those ripping taps.
· If water is overflowing from the vent pipe on the roof – get that fix quick smart.
· Have a shower instead of a bath (it uses a lot less water).
· Adjust your shower flow rate to be under 8 ltrs per minute – you may need to get a low flow shower head or put a restrictor in the line.
