There are a few different models of heaters out in the market these days. We’ll explain how to determine which one is best for you. Just like the average water tank, electric hot water systems come in a few different sizes and styles. We understand that the choice is up to the customer, and all depends on your preference and budget at the time, but there are also several factors that should be considered when getting an electric hot water system that suits you and your households needs.

One important factor to consider is the size and where the tank needs to go in the home or unit. The hot water heater should be able to cater for all your household’s hot water needs, regardless of whether it runs on electric, gas or even solar hot water.

Why Does The Size of My Hot Water System Matter, Aren’t They All The Same?

The size of the hot water system you choose determines whether you will have enough hot water to meet the needs of all the hot water you will use throughout the day. You need to consider things like washing clothes, dishes and showers or baths of household members. If you have a system that is too small you will end up with someone missing a shower or other jobs not getting done as the hot water will not provide hot water for everything.

Additionally, if the hot water system is too small then it will risk breaking down as it has increased pressure on it to keep up with demand. This in turn will incur additional costs to you as you will face repair costs.

Additionally, if you choose an electric hot water system and it turns out it is too small you will have increased electric bills as the tank will be reheating more to keep up with the demands of your hot water usage.

Choosing The Right Size Electric Hot Water System.

There are many factors you need to consider when purchasing a hot water tank. Before getting an APT Plumber to have a hot water system installation, you will need to make sure that you consider the number of people that live fill-time in the home, and then consider the number of visitors you may have also. You need to think about how long everyone showers for, what appliances use hot water like the washing machine and the dishwasher. This will all add up and give you an indication of the amount of hot water you will need to store in the tank on a daily basis.

The Number if Outlets Attached to the Hot Water Heater.

Thought needs to be given to the number of outlets attached to the electric hot water system you install. For example, if you have a single shower attached to the system you will only need a small heater as it will have more time to heat in between showers. However if you have an ensuite and a bathroom both using showers at the same time then you will need to buy a large electric hot water system to cope with a large amount of usage.

Are you wanting a Tank or Tankless Electric Hot Water System?

There’s a lot to consider but this could be a deciding factor, tank or tankless. The tankless hot water heater features built-in coils that allows you to have instant hot water whenever you need it. This system is more expensive however the heating method is more efficient than the tank storage option.

However, it is essential to note that the tankless hot water system can only provide approximately 11.5 litres per minute making them less efficient if two people were showering at the same time.

Storage tank heaters are more popular as they have a much more affordable low upfront cost. However, they are not as energy efficient because they heat more water then you may need. It is recommended that storage hot water heaters are the better option if you have a large family or need large amounts of hot water.

How Much Space You Have In Your Home Can Affect the Tank You Purchase.

Having a large use if hot water is one thing but you must consider the place the tank will be stored as this will in the end effect the size tank you can buy. You need to consider where you will be storing the tank without wasting any unnecessary space. If you have minimal room for storage at home then you should strongly consider a tankless system because they are compact and can be installed in small areas such as a cupboard.

On the other hand though a storage-tank in your home needs a large area for installation too and it may not be the right option if space is minimal. It can always be stored outside or in a garage if space is very limited in the home.

How to Size Your Electric Hot Water System

First and foremost, you need to completely understand the sizing of the space the hot water system will go. Hot water systems differ in sizes and depend on the FHR which is short for the First Hour Rating. This represents the number of litres of water that the hot water heater can produce per hour. Additionally, thankless water heaters are sized depending on the number of litres produced per minute as the temperature rises.
