Water heater considerations before buying:


The Types of Water Heater to Buy

A water heater has two types, the instant water heater, and the storage water heater. Instant water heater works when the water passes through the tube pipes heats the water instantly.  On the latter, storage water heaters are electric heaters with an insulated storage tank where the water is stored and heated up before flowing through the tap or showerhead.

You should consider the type of water heater first before getting one. Weigh options if you want an instant water heater or a storage-tank water heater. It is also best to consider hiring a plumber that can install this water heater in your household.


Product Costing

The cost of the product you will buy will always matter if you are a conscious consumer.  Factors like its price, can affect one’s decision making on buying water and can only be answered when addressed specifically on what brand or water heater type you are planning to acquire. Luckily, there are some popular water heater brands in Singapore that could fit your budget with still a high-quality grade product. The cost of a water heater unit varies from the brand, model, and water heater features that you will be choosing. In the market, getting an instant water heater is much cheaper than the storage water heater units and there are available brands Champs or Ariston that is cheap but still has a good quality and can work efficiently.


Water Heater Installation


Choosing where to install your water heater is also a factor that you should consider.Instant water heaters are usually small in size and do not take up too much space. On the other hand, storage water heaters are bulky and installation costs more especially in HDB or Condos in SIngapore.

For your instant water heater, it is advisable to have them positioned near a powerline to avoid having additional charges with the extension cords. Try to contact  a trusted plumber in Singapore who can help you with your water heater installation.


Pressure and Temperature Consistency of the Water

Most instant water heaters have restricted water pressure. This is to ensure that the water flowing is spontaneously heated. It has a built-in restrictors inside the instant water heater and helps the water to at least reach 39°C.

Water heater interlinks water pressure with temperature consistency. Instant water heaters that are used at the same time will experience water pressure decrease especially when other water taps are open. Thus, affecting the water heater temperature due to the unstable water flow.

However, due to technological advancements, Ariston made a way to solve such issues. They have come up with a model called Ariston SMC33 Instant Heater and claims that “With the innovative new technology, Ariston SMC33 Instant Heater will provide you with consistent temperature and water pressure of your desires”.

On the latter, a  storage water heater provides adequate water pressure and temperature because the water is heated in the tank before being used. The only thing that can be a problem with it is the water holding capacity.


Energy consumed


People nowadays have become much more caring for their environment, and as much as possible, they will go for something that can be beneficial for them and for the environment.

Your energy consumption affects and adds up to the heat that causes global warming. That’s why an event called “Earth Hour” is made. When you want

to save much energy, choosing an instant water heater can help you with this

On the other hand, a storage water heater consumes more energy because of its size, and it stores heat in the tank.
