Hot Water Heaters
Heating water consumes significant amounts of energy Sustainability Victoria.
For a family of 3:
- 0.54 tonnes/year for electric heat pumps
- 0.27 tonnes/year for solar natural gas boosted
- 0.95 tonnes/year for natural gas storage
- 0.66 tonnes/year for instant gas hot water
The target needs to be 1/15th of current hot water heating systems (Australians currently produce 15 tonnes GHG/year and we need to reduce emissions to 1 tonne/year).
If we assume that current hot water heater technology generates on 0.5 tonnes/year on average, then the target will need to be 0.03 tonnes/year
None of the options above will reduce the amount of GHG emissions sufficiently to achieve 1 tonne/person/year or the 1.5degC of global temperature rise (67% confidence) Greta Thunberg Climate Delusion
It is not possible to turn down the temperature of these hot water systems and use less energy because of the risk of creating ideal conditions for Legionella bacteria.
Solar Hot Water Showers
Outdoor camping solar showers are a step in the right direction. They hold 20 litres of water or more. However most are made using PVC, which ends up contaminating the water (PVC has a strong recognisable odour)
Building a DIY Solar Hot Water Shower
If you shower at the end of the day you can enjoy a warm shower for free using the sun's rays.
Build yourself a Solar Oven that can hold 4 litres of water. It is easier to use thin dark metal pots. A standard solar oven design should hold two pots, with 2 litres of water in each pot.
The Solar Oven is made by painting the inside of a cardboard or metal box black using paint. Attach some clear plastic or glass to the top of the oven. This arrangement will help collect and trap the heat from the sun.
Place your dark metal pots filled with water inside the oven. The oven needs to be in a sunny and protected location.
When the water is hot (80 degC), simply decant the hot water into smaller PET bottles 3/4 filled with cold water. Topping up each bottle with the hot water will produce warm water for showering.
The lid of each PET bottle needs to have small holes drilled into them. This way the caps will function similar to a standard shower head. Bottles can be carried up to the shower cubicle using two buckets to balance the load.
To conserve the heat in the water bottles place them in an esky or insulated container until ready for use.
Create a holder in the shower cubicle so that each bottle can be held in place and release water.
