worker setting up a hot water cylinder at home

You don’t really realise how important hot water is for your home until you have to go without it! Hot water is used for many things around the home, most important being your shower, but is also used for things like washing clothes and dishes.

If you find that your current hot water system has gone, you need to get that fixed as soon as possible, unless you like having cold showers. But before you make a rash decision, you really need to think about it because there are a lot of different options for a hot water cylinder and beyond.

So, have a read on below at some of the things you need to consider when purchasing a new hot water system:

Heating Method

There are a number of different ways the hot water system can heat up the water, there is gas, heat pump, solar or electric. Each of these methods all comes with there own advantages and disadvantages, so make sure you do your research to find out the one that is best for your individual situation.

One of the biggest factors that people look for when purchasing a hot water system is the price. You’ll find that an electric hot water system is generally the cheapest, followed by gas, and solar and heat pump are usually the more expensive options.

Water Usage in Household

It is important for you to purchase a hot water system that will be able to handle the size of your household and the amount of water it uses. There is nothing worse than being the last one into the shower for the morning, only to find out that everyone else has used all the hot water!

It can be difficult to know what you need in this case, so it could be a good idea to get the assistance of a hot water supplier. They will come over to your place and analyse important factors and suggest a recommended hot water system for you. If you are getting someone to recommend a system make sure you get two separate quotes so you can compare.

Tank or Continuous

Hot water systems can either come from a tank, meaning it takes a little longer for the water to heat up, or have a continuous flow, meaning the water is instantaneously heating up. There are certainly advantages and disadvantages of each, so this is something to look out for.

No matter the heating method you are thinking of going, you’ll get a storage tank option. If you do choose to go down the tank option, then you have to think of the type of tank you want to get. You will also need to consider the placement of the tank; a warm and insulated spot is best.

For continuous flow, most models are used with gas, although there are also electric options available now as well. The good news is that due to the fact that there are no heating losses like with the tank option, you’ll find that over time it is cheaper going with this option.

Energy Ratings

It is always important to consider the energy ratings, something that may cost a little bit more to purchase and install today might end up saving you more money overall because it is cheaper to run.


Hot water systems will come with a star-rating label, however you should take this with a grain of salt, as this is not something that is not currently regulated by the Government. Hot water systems energy rating is different to that of what you would typically find on a fridge or washing machine appliance.
