What Types of Hot Water Systems are more Energy-Efficient?


Last Updated on November 2, 2022 by davidharnold

In today’s world, many households use and rely on hot water systems in their day-to-day lives. But, when the system becomes old, you must not wait until it deteriorates. In such a situation, you have to consider many options and think about replacing the system. So, in this article, you will learn more about the different types of hot water systems. Such systems will let you decide about a system that can be appropriate for your household requirements, and which types are the most economical and energy efficient.

#1 Solar hot water systems

When you come across a solar hot water system, these are the most efficient systems available in the market. As the system starts working, it offers hot water through the heat obtained from the sun. Soon after producing the heat, it will transfer it to the water and let the warm water flow through the pipes. But, if the system runs on electricity, it will not be at par with natural gas pumps.

However, the hot water system will be better than heat pumps concerning emissions and operating costs. On the other hand, if you don’t install the panels in a suitable location, with the best positions to obtain as much sun light as possible, such systems can be less efficient. The water stays hot whenever there’s less sunlight outdoors due to the gas booster element. Apart from everything else, you may be eligible to get government rebates when you start using this option.

#2 Heat Pump hot water systems

Heat pumps are quite efficient compared to other systems based on a particular technology. Moreover, such systems are environmentally friendly, and they use renewable energy. Consequently, such systems draw in ambient air, circulating the air around the evaporator coil. The dehumidified air is sent out from the hot water system. The refrigerant is then pumped through the compressor, and this step further increases the temperature. The system then transfers the heat throughout the tank through a circulation process.

Due to the process of heat circulation, the heat pump becomes two to three times more efficient than a standard water heater. In addition to heating the water, the heat pump also cools and dehumidifies the air in the surrounding space as heat transfer takes place. You can also use heat pumps and solar panels in your house. These panels will heat the water directly without the use of electricity.

#3 Gas hot water systems

If you’re looking for an affordable option to heat water, you can think about installing a gas hot water system. As the entire system uses a gas burner, it helps to heat the water continuously. The system will also help maintain the water temperature up to 60°C. Way ahead, when you use a continuous flow system, the burner gets ignited automatically only when the household needs hot water.

Hence, such systems tend to emit fewer greenhouse gases with the overall operation in mind. Eventually, you will be happy to use a cost-effective and long-term option when the system is known for low usage rates. But, if you will use LPG bottles often, you will not afford to run the water system when the need arises.

#4 Electric hot water systems

When you consider an electric hot water system for your family, an electrically heated system can be relatively cheap to purchase. However, you have to bear a high cost when using the system frequently. If you use a large tank for heating water, you will need a high current.

Besides many components, the electric water heater has a heating element. Soon after the cold water enters the tank, the heating element starts heating the water. Once the water gets heated to a certain temperature, it moves up another pipe. This pipe later distributes the hot water through outlets across the entire house. These are the least energy efficient hot water systems available, but the cheapest to purchase.

Bottom Line

People living in Queensland are seeking energy-efficient water systems. Such systems will further help them save on energy bills. But, by incorporating a dedicated circuit or a controlled load tariff, the household can ensure proper usage of electricity.

Depending on the electricity network, the arrangement will help supply current to the system during peak hours. The system will heat the water effectively and store the water for later instances.
