Sometimes, your hot water system breaks down and needs to be replaced. In such a situation, it’s not always possible to do your research and choose the best replacement for your needs. It usually results in purchasing the same type of system again. It is not always the best choice as you may miss out on a better option. To avoid this situation, read this hot water systems are buying guide. It will help you understand the different types of hot water systems, their pros and cons, and which size system is suitable for your household.

DistinctPlumbing solar water heater is a system that collects sunlight from the Sun and heats it. A solar water heater uses parabolic mirrors to focus the Sun’s energy onto pipes. The water is then pumped back into the building. The solar heating system is not as effective as a plastic bottle standing on a window ledge, but it’s still a viable option for home hot water systems. A solar hot water system can significantly reduce your heating bills while still getting hot water.

A solar hot water system works in both summer and winter. A solar panel can supply up to 95 per cent of the hot water in summer and 20 per cent in winter. The downside to solar water systems is that they depend on a part-time energy source, so that they won’t meet 100% of your needs every time. However, installing a solar panel can expect about half to two-thirds of your hot water needs in the summer and less than five per cent in the winter.


When deciding on a new hot water system, you must weigh each option’s cost and carbon footprint. While gas and electric hot water systems are more expensive up front, off-peak electric models will cost you the same amount over the life of the heater. You will also have to pay attention to the rising electricity prices that you must account for throughout the heater’s life. Furthermore, it would help if you considered whether your location allows electric hot water tanks.

Natural gas

Natural gas hot water systems have numerous advantages. Not only are they more environmentally friendly, but they also cost less than electric hot water systems. Compared to LPG, natural gas is also more cost-effective, as gas rates do not fluctuate during peak periods. In metro Victoria, a family could save $495 by switching to natural gas from electricity. Read on to learn more about these advantages. Let’s start by reviewing the pros and cons of natural gas hot water systems.

Natural gas hot water systems use a burner that sits under the water tank. As the water warms, the burner heats it and sends it out through an overflow pipe and pressure relief valve. A flue runs through the middle of the tank to let the gas-burning fumes and hot air escape. They tend to have a lower initial cost than other options, but the cost of the gas connection may be high.

Tank storage system

A conventional hot water storage tank will leak every five to fifteen years. A tank with a vitreous-lined interior is better insulated and less likely to leak. These tanks have a shorter warranty period than their mild steel counterparts, but they do not have to be replaced often. In addition, some manufacturers provide an extended warranty kit that includes an anode rod and other components. It is crucial for those who want to protect their investment and ensure a long-lasting tank.

The temperature distribution inside a tank is affected by several variables, including temperature and flow. In a horizontal tank, for example, the temperature is higher at the top and lower at the bottom. In keeping the hot water temperature at the top of the tank, a thermal barrier can be placed on both sides of the tank. These double barriers are practical thermal and flow barriers that prevent cold water from entering the tank.

Unvented system

An unvented DistinctPlumbing hot water system is a heating system that runs without a vented pipe. Water in this type of system expands but does not rise to a temperature of more than 60 degrees. The expansion vessel is usually attached to the hot water system but can also be part of the cylinder. A qualified G3 heating engineer should carry out the installation of an unvented system. There are also specific regulations regarding installing this type of heating system.
