What Size of Water Heater Do I Need?

In Adelaide, a geyser, also known as a water heater, is a common household appliance. It generates hot water for a variety of uses, including bathing, cleaning, and laundry. When it comes to buying geysers/water heaters, many of us are perplexed. After entering a store, a slew of questions arises, culminating in purchasing a heater that falls short of our expectations.

If you have a small-sized geyser tank installed, the discomforts increase when you run out of hot water before you finish your shower. On the other hand, if the geyser is too large, you’ll end up paying a lot of money for heating water because you’re not using it to its full potential. These are common issues that everyone encounters.

So, before making a purchase, these things must be determined.

Your ideal water heater should have a sufficient storage capacity. In terms of water storage, a conservative or conventional water heater is the best and right choice for you. A full-sized tank water heater will store about 20 liters of hot water and serve your toilet, laundry, and kitchen simultaneously, while an instant water heater will only provide a few liters of hot water at a time.

However, if you only need a rough estimate (rather than an exact calculation), follow these guidelines:

30-40 gallons for one to two people; 40-50 gallons for two to three people; 50-60 gallons for three to four people; 60-80 gallons for five or more people

We’ll explain why the figures above are only “guesstimates” and how they may not correctly meet your hot water requirements. We’ll also show you how to figure out what size water heater you need based on your requirements (and saves you money).

Sometimes, all a homeowner wants is a rough estimate of water heater sizing to figure out how much their water heater installation will cost.

Conclusion: So, what is the ideal size?

The ideal water heater size is close to the amount of hot water needed all at once. If people take baths one at a time, each using 25 ltr of water, a 25 ltr or 15 ltr water heater can ensure that the water is at the ideal temperature when they take a bath (at places where the tap water temperature is not too low). If the tap water temperature is too low (especially in cold places), only a 25 ltr capacity water heater will suffice if a bath requires 25 ltr of water. Because 50 ltr of water can be used simultaneously if the water heater is connected to two bathrooms, the optimum size is 25 + 25 = 50 ltr. This isn’t to say that a 6-liter water heater won’t suffice; it just means that it will take longer to heat the same amount of water, or you may end up with cold water at the end of your bath. The best sizes are those that produce enough heat for maximum instantaneous use.

So, if you are looking to buy a heating system for hot water in Adelaide, all you need is to ascertain your requirements and choose the right one.
