How to Choose the Right Hot Water System for Your Home

There are many things to consider when buying a hot water system. The most important part of the system is the combustion chamber or firebox. If you buy a hot water system without considering the combustion chamber’s design, you will likely face performance issues that are hard to solve. You should also consider the cost and maintenance of your new system. Hopefully, this article will help you choose the right hot water system for your home.

Electric and gas hot water systems each have advantages and disadvantages, but electric water heating tends to be less energy efficient. It is due to the inefficient operation of power plants and transmission lines. As a result, electricity generated is usually only 30 to 45 per cent efficient, resulting in large amounts of wasted energy and negative environmental impact. Furthermore, gas is delivered through a pipeline. While the latter is more efficient, it is still inefficient and can result in losing up to 10 per cent of the power.

Electric hot water systems have lower initial costs but are the most expensive to operate over their 13-year life. Gas and electric water heaters have lower initial costs but require much more maintenance. Solar water heaters are the most cost-effective and efficient and should have a UEF rating of at least 2.75. Depending on your climate zone, you might need to purchase a larger water tank. However, the extra cost is well worth it.

Storage capacity

The storage capacity of hot water systems can vary depending on the household size. For example, a restaurant serving only dinner would have a smaller capacity than a more significant business. The water in the system would be pre-heated but not hot enough to keep up with demand. The capacity of a water heater is essential in determining a heating system’s overall energy efficiency.

Hot water systems come in two main varieties: tank and tankless. The former is cheaper but requires more installation work—both use the same heating element to heat water. In addition, tankless hot water systems may use a booster element to provide extra heat. The cost of a tankless system is between $3000 and $4000. However, there are advantages to tankless systems. For example, most can run continuously without needing to drain the tank.

The price of a hot water system depends on the size of the system and the number of bathrooms and people in the household. If your household is larger than the average, you may need to pay more for the installation. A free health check will help you determine which type of hot water system is right for your family. Also, you need to factor in additional costs for labour. The size of the system can affect the cost, as larger systems tend to use more hot water than small units.


Although hot water systems are complex, routine maintenance is crucial to ensure they perform to their highest capacity. Routine maintenance is especially crucial for continuous flow hot water systems, as they do not need to store water or build up pressure and require less attention. Whether you’ve installed a new system or have an older model, it’s essential to check your hot water system to ensure it works properly. Professionals can check components, ensure proper water pressure, and perform a check on temperature-pressure relief valves.


Before installing a new hot water system, you should consider the size of your home. Typically, a one-person home needs fifty litres of hot water per day. The size of your hot water system should reflect this. Also, take into account the price. A high-quality hot water system will likely increase your home’s value and save you money in the long run.
