How to Choose the Right Hot Water System for Your Home

   Adam Wilson is on the blog today to share some ideas on choosing the correct Hot Water System for your home. This can be such an important and expensive choice. Enjoy the article! 

Having a functional hot water system is essential for a comfortable home, and if you’ve ever had your hot water system suddenly break down, you’ll know just how much we all rely on it. Whether you’re in the market for a new and improved hot water system or have had yours suddenly stop working and need to find a replacement immediately, we’ve got the breakdown to help you make a quick decision.

Because water heating accounts for a large part of your household energy use, it’s worth shopping around before splurging on a system. Check the energy rating to ensure the hot water system will be kind to your wallet and the environment.

The Heating Method

Hot water systems are available in a few different heating methods: electricity, gas, solar and heat pump. Each has their own benefits and drawbacks, with some being more suited to certain types of households than others.


Electricity is used to heat the storage tank system and is generally cheap to buy and install, but also the most expensive to run. To save money, you can opt for a system that runs on off-peak electricity, but this will, in turn, require a larger tank. This means that off-peak electricity isn’t a viable option for all homes.


If you already have a natural gas connection, it makes sense to go for this option. Gas is known to be cheaper than electricity, and gas will also heat your water as needed, resulting in lower operational costs.


Solar panels require a significant investment to install, but can often end up being the most environmentally-friendly and cost-effective in the long run. If you already have solar panels installed, a solar hot water system will make perfect sense for you. Government rebates are also available to offset the purchase cost.

Heat Pump

Heat pumps are a more efficient form of the electric storage tank system. By extracting heat from the air, heat pumps are able to use it to heat water. These can be noisy when installed, and work best in warm or temperate conditions, meaning they may not be applicable for all homes.

Storage Tank or Continuous Flow

After deciding which method of heating, you prefer, you then need to decide whether to go for a system with a tank that stores hot water, or one that heats water as needed. Most systems use a tank, with stainless steel being the most long-lasting tank.

Continuous flow systems, on the other hand, only heat water as you need it, meaning it takes a few seconds before the hot water starts flowing from the tap. Most of these are gas models, although some electric models are available. The main advantage of continuous flow systems is that there is no heat loss, meaning they are cheaper to run.

Adjust for Your Household

Each household has different consumption requirements, meaning it’s important to get a hot water system supplier to analyse your home and recommend options accordingly. This will consider how many residents there are, how much hot water you use and when. The right hot water system for you will vary depending on whether the whole family shower in the evenings only, or whether you run the dishwasher every day.

Solar hot water systems are the most efficient in the long run but aren’t always feasible or appropriate for every home. Going by the size of your household, here are some good recommendations:

1-2-person household: Continuous flow or small gas storage hot water system.
3-4-person household: Gas hot water system or heat pump
5+ household: Continuous flow hot water system, gas storage units or heat pumps

Energy Efficiency

To save money on your energy bills and to protect the environment, have a look at the energy star ratings of the models you are considering. Gas hot water systems will display a star rating, with more stars meaning higher energy efficiency (aim for as close to 6 stars as you can).

When it comes to electric hot water systems, Minimum Energy Performance Standards are a good indicator to look out for. Again, look for the better-performing models, as these will consume less energy and resources.

    Selection process depends on budget and individual choice.
    I think Heat pump system is an Eco-friendly & best alternate choice of solar powered system.
