What Size Gas Geyser Do I Need?


Gas geysers are a great way to save money on your energy bills. They are also one of the most efficient ways to heat water in South Africa, so it’s no surprise that they have become so popular. But with all the different sizes and types of gas geysers available, how do you know which is right for you? In this article, we’ll discuss what size gas geyser is best for your home and provide some tips on choosing the right model.

Determining The Right Size Gas Geyser For Your Home

The size of gas geyser that you need depends on several factors, such as:
-Your household’s hot water needs;
-How many people live in your home;
-The number of bathrooms/showers connected to the gas geyser; and
-Whether or not you use a dishwasher or other appliances that require hot water.

To help determine what size gas geyser will be suitable for your home, take into account these factors and then follow these steps:

1) Estimate How Much Hot Water You Need Per Day – This can vary depending on how many people live in your house but typically ranges between 30L per day (for two people) up to 90L per day (for five people). If you’re unsure about this figure, contact an expert who can give more specific advice based on your individual requirements.

2) Choose A Model That Is Large Enough To Meet Your Needs – Once you’ve determined how much hot water you need per day, look for a model that has enough capacity to meet those demands. Make sure it’s large enough by checking its stated capacity against the estimated amount needed each day—if it’s too small, go with a larger size instead. Additionally, bear in mind any appliances like washing machines or dishwashers which might also require extra hot water when making this decision.

3) Consider Efficiency Ratings And Other Features – When considering different models always check their efficiency ratings (rated from A+++ down to G), plus any additional features like child safety locks or timers which may be beneficial depending upon individual circumstances and preferences. Generally speaking though efficiency should be prioritised over extras when selecting a new unit since this will directly influence running costs over time as well as saving energy overall..


Choosing the right size gas geyser can make all the difference when it comes to both performance levels and long term energy savings – get it wrong however and not only are there potential financial implications but also potential safety risks too! By following our simple three step guide above though hopefully we’ve been able to point out key considerations when shopping around for one so next time someone asks “What Size Gas Geyster Do I Need?” at least now we have an answer!
