Tankless water heaters have become popular among Australian homeowners due to the many advantages they offer compared to traditional water heaters that come with a tank. Unlike conventional water heaters, which use energy to store hot water waiting to be used, tankless water heaters are known for their energy efficiency since they are capable of heating water only when it is needed. This explains why they are also called on-demand water heaters. 

In addition, contrary to traditional tanks, which will need to be entirely replaced in case of a leakage, demand-type water heaters can be repaired. When a tankless heater is correctly sized, it can provide an unlimited supply of hot water.

With all the benefits a tankless water heater has to offer, you should consider the following points when buying one:

Choosing a correctly sized unit

Manufacturers size their heaters by finding out the temperature rise needed to achieve a certain flow rate. If you have these two factors calculated for your household or business, you can easily choose an on-demand water heater that meets the demands of your family.

Selecting a decently energy efficient model

Energy savings being one of the major benefits of an on-demand water heater, it is one of the things you should consider when choosing the unit that will cater for your needs. You should also note that the efficiency of a tankless heater decreases as the demand for hot water increases. Despite this fact, the demand-type heater performs way better than the traditional water heater when it comes to energy savings.

Choosing the right warranty

Different manufacturers and different models have varying warranties. Many manufacturers will require you to register your tankless heater and have it installed by a profession in order for you to qualify for warranty coverage. You should also compare warranties of various manufacturers. If a manufacturer has a reasonable warranty time frame, it simply means that they believe in the reliability and quality of the tankless heater that they are selling. This will, in turn, give you confidence in that manufacturer.

Selecting the right fuel type

The type of fuel you use will determine the energy efficiency of your tankless heater, hence determining your annual expenses. There are fuel choices to choose from, like electricity, natural gas and propane. You should compare the price of every fuel before making a decision. Tankless heaters that use gas are more costly than the electric units. They, however, have better performance than electric units from an energy-saving point of view.

If you keep the above-discussed points at the top of your mind when shopping for a tankless water heater, you should be able to make the right purchase. Contact a company that offers plumbing services for additional advice.
