Hot Water and High Energy Useage

By Travis on February 11, 2009


Steaming hot water on tap is a modern day luxury that we all love to take advantage of. The downside of that long hot shower or soak in the bath is that hot water can be a major household expense. Given that hot water can account for half the energy use in a typical home, there are some simple ways to reduce hot water use, save energy and also make considerable cost savings.

Wash in Cold
In most cases a load of washing can be done just as effectively in cold water as it can in hot water. Using cold water can save 90% of the energy used in doing a load of washing .

Shorter Showers
It’s simple and effective. Just take less time in the shower. If you need encouragement to have shorter showers, numerous types of timer are available for use in the bathroom. These range from simple 3 minute hourglass timers to waterproof electronic timers.

Water Saving Showerhead
Water saving showerheads have come a long way in recent years. Modern, efficient water saving shower heads don’t reduce the quality of your shower but can save 50% of your water usage. They are easily installed by anyone with even the most basic of home maintenance skills.

Exposed hot water pipes – particularly when the water heater is located outside – should be well insulated to prevent loss of heat.

Fix Leaks and Drips
Leaks and drips from taps and pipes should be fixed quickly. A dripping tap can account for 10 wasted bathtubs of water every month. Depending on where a leak is located it can also cause major structural damage to your home

Create a Heat Trap
The hot water outlet pipe should go down the side of the hot water tank for at least 150mm. This means that rising heat will create a heat trap around the pipe and save energy.

    Don’t forget to insulate the water heater itself. The water heater blankets are about $15-$20, available at Lowes, Home Depot, Ace… Any do-it-yourselfer can install them in about 30mins
