Avoid continuous flow systems with standing pilot lights.
Install a timer on peak rate electricity storage units.
Have your plumber rectify any problems of water hammer.
For solar hot water systems, install solar collectors to face true north. Soar collectors should not be shaded by trees or nearby buildings.
Constant pressure storage tanks boosted by solid fuel heaters should be installed directly above the solid fuel heater to make full
use of the natural rise of heated water to supply the tank.
Ensure your unit is not oversized for your household.
It is generally not cost effective to buy a second hot water heater to service remote rooms.
Install your system as close as possible to the kitchen, bathroom and laundry, which are the main hot water draw-off points around the home. If this is not possible, install it close to the kitchen, which typically uses small amounts of hot water throughout the day. This helps to keep pipe lengths short, minimising installation costs and heat losses from pipes. It also overcomes wastage and the inconvenience of having to wait for long periods for hot water to start flowing from the tap.
Keep the hot water system sheltered " reduce heat losses from storage tanks and protect any pilot lights from draughts.
You can add extra insulation to a storage tank to reduce heat losses, especially if it is in a very cold or exposed position. This could save you up to $15 a year. Foil-backed insulation blankets wrapped around the tank are most suitable (dont restrict flues or air vents). Also check with the manufacturer to ensure the warranty wont be affected before installing extra insulation.
Turn the unit off if you're going away for an extended period. Some units have a vacation setting to make this easier.
Check the gas flame in your gas unit. When it is burning efficiently it will be blue in colour. If it is yellow you should have it checked by a service person.
If installing a solar system, ensure the roofs structural strength is assessed (by the installer) to ensure it can support the weight of the system.
To maximise performance of your solar system, when possible do jobs requiring hot water early in the day. This allows the water remaining in the tank to be reheated by the sun.
