How Do You Choose the Right Domestic Hot Water System Size & Type?

When it comes to domestic hot water, there are a number of factors to consider when selecting the right system for your home, including the fuel type, your climate, the size of your home and family, and how much hot water you use. Choosing the right size is very important – if you pick something too small, your family will constantly run out of hot water. If you choose something too large, you will spend a lot of money and waste a lot of electricity to run it. Your goal is to find a water system storage tank size that will cover your needs but not exceed them.

Generally, a family of 4 will need a 125–160L storage tank if they have an electric hot water system, a 135–170L storage tank unit if they have gas hot water, about two panels plus a 300–360L tank if they have solar, or a 270-315L tank if they have a heat pump system. There are also gas or electric instantaneous water heaters (also known as continuous flow systems), which don’t have a storage tank because they heat water as it is needed.

Types of Domestic Hot Water Systems: Solar Water Heaters, Gas Storage Systems, Electric Storage Systems & Continuous Flow Systems

Electric continuous flow water heaters

There are a number of different types of hot water systems on the market. Solar domestic hot water systems are a great option for those looking to reduce energy consumption. They have great energy efficiency because they rely on the sun’s energy to heat water – this means they don’t use electricity or gas from the mains as their primary source of energy. One downside of solar power domestic hot water systems is that they can be expensive to install.

Domestic gas hot water systems are a popular choice for many homeowners because they are relatively inexpensive to install and operate. Domestic gas hot water systems typically use either natural gas or propane to heat water. One downside of gas systems is that they can produce carbon dioxide emissions, so they are not the best choice if you want to reduce greenhouse gas emissions.

Finally, electric domestic hot water systems are a popular choice because they are easy to install and operate. Electric systems use electricity to heat water. One downside of electric storage systems is that they can be expensive to run. If you’re not sure which system will be best for your needs, just give us a call.

FAQs About Domestic Hot Water Systems

What is the cheapest hot water heater to run?

Continuous flow hot water systems, also known as instantaneous or tankless hot water systems, are small units that heat water on demand. Unlike hot water tanks, which store and heat water in advance, continuous flow systems provide a never-ending supply of hot water. This makes them ideal for households with high demand. Generally, continuous flow water systems are available in both electric system and gas system models, making them a versatile option for most homes in Brisbane. If you're considering a continuous flow system for your home, be sure to speak with a licenced professional to determine the best continuous hot water system for your needs.

How long do water systems last?

The average lifespan of a typical hot water heater is around 8-12 years. However, this number will vary based on the type of system you have installed in your home as well as the quality of maintenance it receives. If you want to ensure that your water heater lasts for as long as possible, it is important to have it regularly serviced by a qualified technician and to have it repaired as soon as faults are noticed.
