What Size Hot Water System Do I Need?

When it comes to choosing a new hot water system, many homeowners feel overwhelmed by all the options available. How do you know what size system you need? What type of system is best suited for your household? How much will it cost to install? In this blog post, we will answer these questions and help you choose the right hot water system for your home.

What factors should you consider when choosing a hot water system size?

First, you need to consider your household’s water usage. The average family of four uses about 300 litres of hot water per day. If you have a larger family or if you entertain often, you may need a system that can provide more hot water. Of course, a household of just 2 adults will use far less water than, say, a family of 5, and you need to factor this into what size hot water system your household needs.

Try to calculate roughly how many litres of hot water your household consumes per day, keeping in mind that 160 litres per day typically caters for three 5-minute showers and additional minor hot water usage in the kitchen and laundry.


Which type of hot water system is best for your needs?

There are many types of hot water systems available on the market, and each type has its own benefits and drawbacks. Here are some of the most popular types of hot water systems:

  • Storage tank: This is the most common type of system. A storage tank stores hot water until it is needed, and then heats the water as required. Storage tanks are available in a variety of sizes, so you can choose one that suits your needs.
  • Tankless: A tankless system does not store hot water; instead, it heats water on demand. This type of system is becoming increasingly popular because it is more energy-efficient than storage tank systems.
  • Solar: Solar hot water systems use the sun’s energy to heat water. Solar systems are an environmentally friendly option, but they can be more expensive to install than other types of systems.

How much will a new hot water system cost to install?

The cost of installing a new hot water system will vary depending on the type and size of system you choose. Storage tank systems tend to be the most affordable option, while solar systems are usually the most expensive (keeping in mind that with solar, you’re removing this energy usage from your future electricity bills entirely).

Tips for reducing your household’s hot water usage

  • Install low-flow showerheads, as they can help you save water and money. These showerheads use less water than traditional showerheads, without sacrificing water pressure.
  • Fix leaks: A small drip from a faucet can waste a lot of water. Be sure to fix any leaks in your home, no matter how small they may be.
  • Insulate your pipes, as this will help prevent heat loss and save you money on your energy bills.
