How Do Instant Hot Water Dispensers Work

Our instant hot water systems have been a game-changer – for both homes and commercial spaces but, how do instant hot water dispensers work? Below we explain how an instant hot water dispenser works and the technology and features that make our systems energy-efficient, safe to use and a great addition to your home or office.

For over 30 years Billi has been supplying Australian households with high-quality water filtration systems. Our products are Australian designed & made in our state-of-the-art manufacturing facilities and feature the most advanced water filtration technology. Here is how an instant hot water dispenser works and why our filtered hot water dispensers are a popular choice.

 

Instant Hot Water Dispensers

How an instant hot water dispenser works will depend on the system, however usually there is a tank that holds the water, heated by an electric heater controlled by a thermostat controlling/regulating the temperature of the water.

Our instant hot water systems for homes are an under bench system so the only thing you see is the dispenser. Our dispensers feature ergonomic, modern & stylish designs that come in a range of finishes so they are a fantastic addition to your kitchen.

 

Economic Benefits

Our systems have one of the smallest footprints on the market so take up the least amount of under bench space possible.

With a kettle no longer required (or a bulky sparkling water machine with our systems that provide instant sparkling water) benchtop space is freed up too.

Our innovative Heat Exchange & energy reclaim technologies make our instant hot water systems energy efficient and industry-leading.

Recovering the waste heat energy produced in the chilling process to preheat the boiling water, allows the water to reach the optimal temperature more efficiently – achieving substantial energy savings.

 

Other Benefits

Other benefits of our instant hot water dispensers include:

  • Water combinations that, in addition to boiling water can include chilled, still and sparkling water for the ultimate convenience
  • Safety features such as a switch that locks off access to boiling water and splash-free boiling water delivery, making them safe to use – ideal for families
  • Highest drinking water quality with premium filters that remove nasties from your water (improving taste and odour too)
  • Easy and cost-effective to install (no cupboard cutouts required)
