Check out the different options and consider your household size, up front purchasing cost and operating costs, space available and energy sources available to you.

A HWS with storage can waste 30% of the energy it uses due to heat loss from the tank and hot water pipework. To minimise the loss of hot water, locate wet areas near the kitchen where frequent small amounts of hot water are used.

When determining the best hot water service for your home consider:

  • Household size, space available, upfront and operating costs, solar access and energy sources available;
  • Ensure roof pitch and orientation is suitable for a future solar water heater. Solar boosted solar electric or gas booster solar water heaters generate fewer greenhouse gas emissions; and
  • Solar and heat pumps may be more suited where natural gas is not available, as LPG can be expensive if a lot of hot water is used. A heat pump can provide a 45% reduction in running costs. For more information read the Heat Pump Water Heater guide for Households;
  • If your system has a storage tank, ensure it is sized appropriately. Too small and you’ll run out of water, too big and you’ll have excessive running costs;
  • Install water efficient showerheads as showering uses the most hot water in an average household (and if you buy a continuous flow HWS make sure the water efficient showerhead is compatible).

Also be aware if installing mixer taps these can waste hot water if not used correctly. Be sure to leave the handle in the cold position.
