The Most Energy-Efficient Hot Water system

Australia is famous for its electric energy-producing facilities at about 243 bn kWh. It exports most of the self-produced energy to other countries. According to Energy Saver NSW reports, Sydney consumes more than 40-100 Terawatt hours of electricity annually. Also, the most used appliance in every household is the hot water unit. That is the reason why most people prefer to buy the best hot water system in Sydney.

To purchase a perfect hot water system, you need to know your requirements. Every family’s consumption has a different set of needs. Here is a guide to choose the most energy-efficient hot water system in Sydney.

Family Size and Usage Requirement

Sydney’s estimated metropolitan population is about 5,312,163. The Australian Energy Regulator reports say the most energy-consuming appliances are Fridges, Air-conditioners, and Water Heaters. In general, the family size in Sydney ranges between 2-4 people.

The more people in a family, the more use of the hot water system. The use of a hot water system differs from person to person. Government statistics state that every person typically consumes 50 L of warm water every day. Hence, you must define your requirement as per your family size and then choose a hot water system accordingly.

Heating Method

Once you finalise your requirement, the next important question arises, what should be the heating method? Should you pick electricity, gas, solar, or heat pump? In Sydney, 30%-55% of the population prefers heat pumps for their hot water consumption.

An electrically heated storage tank is relatively cheaper to install but expensive to run. Natural gas is cheaper than electricity, but its installation is a costly affair, plus it requires ample open space for venting requirements.

The solar method requires collector panels and storage tanks that become comparatively expensive, and also its installation is a time-consuming process. Still, you can derive benefits from government rebates and incentives. A heat pump is an effective form of electric storage tank that functions on the principle of AC and refrigerators. Also, it is comparatively cheaper than solar panels.

Facility: Storage or Instantaneous Flow

According to experts, a storage tank stores up to 300- 360L of water for consumption. In Sydney, the hot water consumption differs climate-wise and household size-wise. In summers, the hot water consumption drops by 70%, and in the winters, the consumption soars to 50L to 70L per day.

Storage tanks are efficient ones as they are made of mild steel, and usually, they come with five to ten years of warranty. Stainless steel tanks are less likely to corrode and also do not require high maintenance.

However, in instantaneous flow, the hot water system heats the water instantly as per your requirement. The hot water systems in Sydney with the instant flow are cheaper than the storage ones but consume more electricity on its use.

Check the Performance Standard

In Sydney, the appliances must match the performance standards as per the MEPS act (Minimum Energy Performance Standards). It applies to electric hot water storage systems, gas hot water storage, and gas systems.

In Sydney, around 38% of the power bill accounts for water heating consumption. Hence, the majority of the citizens prefer purchasing by checking the MEPS label. Not all hot water systems are labeled under MEPS, but you must go for the ones that match the energy consumption standards.
