There are many considerations when shopping for a hot water system. It can be difficult to choose the right system for your needs when there are so many options available. Generally, hot water systems don’t last for more than 10-15 years and because of the expense involved, many homeowners decide it's best to go ahead and replace it with a newer, more energy-efficient system. Read the following article for helpful hints on how to buy the right hot water system.

Electric hot water heaters

The water is heated in an electric storage hot water system by an element located at the bottom of the unit and then stored in an insulated tank, where it is available for use throughout the day. However, running an electric hot water system is the most expensive option.

Gas water heaters

When operated on natural gas, a high-efficiency gas hot water system is one of the most cost-effective types of water heaters available on the market. Gas and electricity prices are going up, so if you have a gas or electric hot water system that needs to be changed, think about getting a more efficient gas or solar hot water system.

Solar water heating systems

Solar hot water systems are more expensive to purchase and install, but their operating costs are much lower than those of conventional hot water systems.

Heat-pump water heaters

Storage tanks are heated by a heat-pump water heater, which harnesses the heat in the surrounding air to warm the water inside. It is far less energy-intensive than an electric storage water heater, and it can bring further economic and environmental benefits if your home is equipped with a solar PV system that generates more electricity during the day than your household's consumption.

How to Choose the Right Size for Your Hot Water Heater

Using a storage heater that is too small will result in constant running out of hot water, while using a storage heater that is too large will result in higher energy costs because it will maintain water temperature even when it is not in use.

As an example, if you have numerous hot water outlets being utilised at the same time, a continuous flow system that is too tiny may not be able to keep up with your hot water demands and may fail. Choosing the proper size water heater is something your water heater supplier can assist you with.

• * The size of a storage hot water heater is determined by the number of people in the home. A larger storage tank is required for a bigger household.

• * It's not how many people live in the house that makes continuous flow or instantaneous systems bigger. It's the number of hot water outlets in the house that makes them bigger.

• * Solar water heaters are sized in accordance with the number of people living in the residence they are intended for. Each additional person requires an additional tank and extra solar collectors.

Replacing a hot water heater that is powered by electricity

If you already have an electric hot water heater, consider replacing it with one of the following:

• * a continuous flow natural gas/LPG hot water heater with great efficiency

• * a natural gas/LPG storage hot water heater with great efficiency

• * an electric-boosted solar hot water heater a natural gas/LPG-boosted solar hot water heater

• * a hot water heater with a heat pump

Changing out a gas water heater

If you already have a gas hot water heater, consider replacing it with one of the following:

• * a gas continuous flow water heater with excellent efficiency

• * a gas-boosted solar hot water heater a high-efficiency gas storage water heater
