Introduction to Choose A Right Water Heater

29th March 2018

Water heaters shoulder the responsibility of providing hot water in your home. They usually send the hot water to your home and bring you the joy of a nice bath, but meanwhile, they also consume a significant amount of energy per year and sometimes cause plumper system problems, for example, pipe leakages. With the relatively high costs you pay for your water heaters (on average, it is the second largest expense for a household item), you may wonder what type of water heater is best for you and your home. To help you make a choice, we write the below article and hope you can make the most suitable decision for yourself after reading this article.



A few Factors play into the process of deciding the best water heater, including the budget for a water heater and the demands of hot water per day.


Storage Water  Heater

The storage water heaters are a traditional type of water heaters. They use the tanks to store the hot water at a fixed temperature and work with gas and electric fuel sources. With this kind of economical water heater, you can access sufficient amount of hot water in your home. However, you may suffer from the continuous heat loss because of the design after using the heater for some time. The heat loss in the standby tank has a negative impact on the energy factor(EF), therefore, may raise your electricity bill.

If you have a relatively tight budget for a heater and share hot water with many family members, maybe the storage water heater is your best choice.

Tankless Water  Heater

Also known as demand-type or instantaneous water heaters, this type of water heaters gets its name because it can heat cold water directly without the use of a storage tank. The gas burner or the electric element inside the water heater raises water’s temperature when water passes through a pipe into the unit. You can enjoy a hot water bath whenever you want to with the use of the tankless water heater without the worry of the empty tank of hot water. Furthermore, the tankless water heater is more efficient than most of the water heaters you can find in the market because the heat loss caused by the standby tank can be effectively decreased. Hence, installing the tankless water heater in the home can help some save approximately, USD100 per household, depending on the family size.

However, tankless heater’s disadvantages are undeniable. A tankless water heater’s flow rate is usually weak compared to others. The flow rate may influence your simultaneous hot water demand in one house. Also, the initial price of a tankless water heater is much higher than a typical storage water heater, which would offset the money saved by its efficiency if you plan to use it only for a few years.


Solar Water Heater

The solar water heater is also widely welcomed and installed in homes during recent years. The relatively high efficiency, long life expectancy and eco-friendly design of this type of water heater raise its popularity significantly.

However, it is clear that solar water heater will bring some inconvenience to a house as well as the advantages. It may have a higher expanse compared to the storage water heater and could be restricted by the uncontrollable water condition. As a result, if you want to ensure the hot water supply in your home, you may need to install another water heater on top of the solar water heater.


Other Factors Worth  Consideration

Fuel Type

If you want to find the most economical as well as efficient water heater, fuel type is a vital factor that worth considering. Nowadays, the electricity, geothermal energy, fuel oil, natural gas, and solar energy are widely used for all types of water heaters.


How many people are there in your family? Do you know the sum of water the house will consume every day during peak?Normally, a family of 3-5 people, which is the most common size of family in Singapore, needs 36-56 gallons of water. As a result, this peak demand may largely influence your choice of the water heater. Besides, the space you prepared for the heater in your house also affects which heater to purchase. Particular types of water heaters are needed to fit in the area in your home.


Installation And Maintenance

Different types of water heaters, fuel types of the heater, local building code requirements and security concerns differentiate way of installation significantly. Hence, we suggest that it is better not to install the heater on your own.

Furthermore, the regular maintenance can minimize the efficiency loss of your water heart and extend its life. Same as the installation, the way of maintenance varies from types to types. For instance, to optimize the efficiency of the solar water heater, a solar contractor needs to conduct checks every 3 to 5 years, while for storage water heater, a check of water pressure and the temperature is advised every half a year. Republic Plumber Quality Service also provides you with assistance to inspect your water heater to ensure that it is functioning properly.


We hope you have acquired some basic but essential knowledge about the water heater, which can help you to make a wise choice of this significant element in your home.
