Which one is the right one

You may feel deluged by the sheer volume of information on hot water and find it hard to know where to begin. So let’s start with some basic questions on hot water systems you could ask yourself to help you make your choice.

Energy Source: Do you want a new heating system that utilises your existing energy source? In this case, you will be restricted by whatever is pre-installed in your home. Is it a new project whereby you can choose or change your energy source?  

Storage Tank or Tankless: A storage tank can hold a considerable amount of water and is readily available for use. Whereas the tankless option needs a sufficient flow rate for the heater to “kick in”. The storage tank can be considerably cheaper to install as it utilises existing pipework and circuitry. A tankless system may require changes to pipework and wiring. A tankless unit is more costly to install but has cheaper running costs. 

What Size

It’s wise to consider the size of your home when changing your water heating system. Is it a small unit or a large house? The design of your home may limit your options as there may be insufficient space for a storage tank. Tankless systems take up less space, so they are ideal for a small unit. If yours is a large home and you want tankless, bear in mind where the heater will be situated. You could waste precious water if it’s placed too far from water fixtures. 

Bear in mind that the flow rate needs to be sufficient to activate a tankless water heater. Low flow rate can result in patchy and inconsistent water temperature. In contrast, storage tanks are heated to a pre-set temperature and therefore are more constant. However, bear in mind that, depending on the size of the storage tank, it can take a long time to heat. When the water is gone, you need it to reheat all over again. Therefore, if you choose a storage tank, be sure that it is of sufficient size to cope with the needs of your household.

Home Plumbing FAQs

Does a tankless system give me limitless hot water?

It’s a simple matter of supply and demand. Is your home large with many water fixtures and a large household? In this case, you may find it better to have more than one tankless water heater. Otherwise, you may find the supply is intermittent and unreliable. If you have a larger heating capacity or more than one, you can potentially have a limitless supply of hot water.

Why not call one of our experienced, licensed hot water plumbers in Wahroonga who will be happy to help you determine what you need. 

How does a tankless system work?

In simple terms, cold water enters the system and is heated as needed by coils or a burner depending on whether you use electric or gas.

Turning on a tap or another water fixture activates the flow sensor. In turn, the flow rate impacts on the pre-set temperature, giving you hot water when you need it.

The size of the home, size of the family and number of outlets it will need to serve, will be relevant to the capacity of your tankless heating system.

Can I replace a storage heater with a tankless system?

It is possible to change a storage system to tankless, but there are several things to consider.

Depending on where it will be situated, it may be necessary to reroute circuitry or piping, and this will increase the cost of installation. If your home is large, you may want to consider multiple units. Take into account the size of your home, household and the heating capacity of your tankless system.

How much will it cost?

It depends on several things. What type of system will you choose? What is the price of your chosen heater? The layout and size of your home will have an impact on cost too. Will there be any adjustment to the placement of piping and circuitry? Consider also running costs. Storage tanks are often cheaper to purchase and install. However, the running costs can be higher than a tankless system.
