Save Money on Energy with an Efficient Hot Water System


With energy costs continuing to rise, most people are looking for ways to save money on their household energy bills. It may surprise some people to learn that water heating is the second biggest energy user in a home behind heating and cooling their homes. To help reduce the cost of heating the water in your home, you can select a more energy efficient hot water system.

Energy Efficient Water Heating

While electric hot water systems in Perth have been the most commonly used systems in households, they consume the most energy out of all the hot water systems that are now available. In fact, they can use as much as 40 percent of the electricity consumed in a household. To help reduce the amount of energy that it takes to provide you with hot water for showers or to wash your laundry, you can have a newer, more energy efficient system installed to provide hot water.

Choosing a Hot Water System

When you are ready to replace your current hot water tank, there are several types of hot water systems from which to choose. The main decision you will need to make is whether to purchase a hot water storage tank or switch to a continuous flow system. When hot water is stored in a tank, the gas or electricity is always running to ensure the water stays hot. This system uses more energy because it is always running.

Hot Water Systems

A continuous flow system uses less energy because the water isn’t heated until it is needed. Since a tank isn’t needed for storage, they also take up less space in your home and you can install a tank less water heater at the point where it is needed. So, you could install one unit that will provide hot water for your entire household or you install smaller units under your kitchen sink or in your bathroom to supply hot water for your bathing needs.

Sizing Storage Tanks

If you decide to use a hot water storage tank to provide your hot water needs, it is important to size the tank correctly to help reduce your energy use. The rule of thumb for determining how much hot water your household requires is to take the number of people in your household and estimate 30 to 40 litres of water per person when using a gas tank storage system and 55 to 60L for an electric system.

The larger the tank is that you need for hot water storage, the more energy it will require to keep the water hot. However, you can help reduce the amount of energy needed by using an insulating blanket around the tank to help keep the water warm. You can also wash dishes or clothes during off-peak hours to help reduce your energy bills. In addition, read the label on the tanks you are considering in order to find one with the best energy rating. Heating water more efficiently can help you save hundreds of dollars per year on your energy bills.
