Tips to Determine the Right Size of Hot Water System for Your Needs

Your hot water system is a substantial investment that you will be making. Therefore, you should take the time to determine what size your home needs before buying a water heater because it can save you money in the long run. There are many things to consider when deciding on which size of the system to buy, and this article will discuss them all to make the best decision for your family.

Types of Hot Water Systems – Include; Gas, Solar, and Heat Pumps


There are three types of hot water systems: gas, solar and heat pumps. Each type has its own set of pros and cons that you should weigh before deciding.

Gas hot water systems are the most common type in Australia. This is because they are relatively cheap to install and run and provide high temperatures quickly. However, they do produce greenhouse gases, so if this is a concern for you, you may want to consider a solar or heat pump system instead.

Solar hot water systems use energy from the sun to heat the water, which means they are environmentally friendly. They can be expensive to install, but they will save you money on your electricity bill in the long run. Additionally, many state governments offer tax credits and subsidies.

Heat pumps use electricity to heat the water, but they are more efficient than conventional electric hot water systems because they can transfer excess energy from one place to another. The downside is that heat pump hot water systems may take a while before you get any hot water unless it’s an off-peak time of day when the cost of power is lower. This means that if your household depends on having instant access to warm or hot showers or baths, then this might not be the right system for you.

Heating Method 

Another thing to consider is the heating method. There are two types of hot water systems: indirect and direct storage heaters. Although both work similarly, they differ in storing their energy before heating it for use.

Indirect tankless gas hot water systems typically run on a combination of natural gas and electricity. They do not need any additional space because they can fit into an existing wall or cupboard – just like a conventional system does now! The downside is that these units require more maintenance than most other types of water heaters because you will have to clean out the unit every so often as part of its regular maintenance schedule. It also doesn’t provide instantaneous-style instant access to or hot showers or baths, either.

Direct storage tankless gas hot water systems are the most popular tankless system. They work by heating a large storage tank with natural gas, providing you with heated water on demand. These units don’t require any electricity to run, so they are a good option for people who want to save on their energy bills. They are also easier to install than other hot water systems because they typically come pre-assembled. However, like the indirect system, these units need regular maintenance and do not support instant access to showers or baths.

System Storage 

The final thing you need to consider when determining the size of your hot water system is how much storage capacity you will need. Storage capacity is significant because it determines how many people can use hot water simultaneously and how long the unit can run before needing to be refilled.

If your household has more than one person who likes to take baths or showers consecutively, you will need a larger storage tank to always have enough hot water available. Additionally, if you like to do laundry or dishes in the evening after everyone has gone to bed, you will also want a large storage tank so you don’t have to wait for the water heater to refill between cycles.

You need to determine how much hot water you will use in a day and then look for the proper storage tank size accordingly. Of course, you can always ask an expert if you are unsure which type or capacity would be best for your household needs.
