Affordable, compact point-of-use hot water systems
Need more hot water than your existing hot water system can provide? Or looking for a hot water system that can fill your sink with hot water quickly? Cut the waiting time to get fast hot water without the lag time with an under sink hot water system.
Under-sink hot water systems deliver hot water directly to a single point-of-use tap. They are perfect for situations wherein there is an increased demand for hot water or if it takes a long time to get hot water to a tap as the system is located far away. Installing an under-sink hot water system for a granny flat or office kitchen can be more economical than upgrading the main hot water system. If you are considering an instant hot water system, contact our hot water plumbers and we will recommend the best solution for your requirements.

What is an under sink hot water system?
Also known as point-of-use hot water systems, they are compact and small and can be fitted in a cabinet under a sink to supply hot water directly to the faucet. They can heat the water instantly as the water flows through the unit or heat and store 5 to 10L of water in a small tank, depending on the model. The storage style units can reheat the water in the tank again in as little as a few minutes.
These hot water systems are available in two style options:
- Storage – with a small tank
- Tankless – instant hot water
