Tankless Hot Water Units in Perth

Tankless hot water units are perfect for any business or homeowner. While they provide a constant supply of hot water, they also are 8 to 35% more energy-efficient than a conventional unit. If you are looking to add value to your home, consider upgrading to a tankless water unit. They are long-lasting and can reduce your energy bills.


One of the most significant advantages of using this type of water heater is that Tankless hot water units can reduce a typical household energy bill by about $100 or more per year on their energy bills. The extra energy costs can be eliminated because there is no need to keep 40 or 50 gallons of water in a tank. Therefore, less energy is used.


What is a Tankless Hot Water Unit?


A tankless hot water unit, also referred to as an on-demand unit, heats water without storing it. The water will only be heated when the faucet is turned on.


Most tankless hot water appliances are small in size. On average, they measure 28 inches by 20 inches by 10 inches. Most tankless units will be able to provide 2 to 5 gallons of hot water per minute. If you are looking for higher flow rates, you may wish to go with a gas-fired device over an electric model. However, an electric unit will be more efficient but can up the cost of your energy bill. 

An electric tankless water heater can use up to 25,000 watts of electricity. Gas units will generally last longer and are more inexpensive to run. They are also safer than a conventional hot water device but can automatically shut off if there is scale build-up.
