Hot water system.

An instantaneous hot water system is a perfect choice for most households and businesses, because they never run out of hot water, as they do not have a storage tank. The water is heated on demand which significantly reduces energy costs.

  • Continuous flow high-powered units can service both bathrooms and several taps, simultaneously.

  • Instant hot water systems can operate on both gas and electricity.

The Many Benefits of Instant Hot Water Systems

  • Hot water systems do not waste energy by keeping water hot in a big storage tank when you’re not using it. This means cheaper operating costs.

  • They heat water only when you need it. So if you’re on holiday, you don’t have to worry about a storage tank causing unnecessary costs.

  • Flexible installation options. The units are small, so they can fit almost anywhere.

  • Solarhart, Vulcan, Rinnai, AquaMax, Rheem, Dux and Bosh all provide indoor and outdoor models that cater for both homes and business.

  • Reduced water wastage. The units are small so they can be placed close to high water use areas such as kitchens and bathrooms so less water is wasted while waiting for water to reach the tap.

  • Instant hot water heaters will usually last almost twice as long as a hot water system that has a tank. Usually 20 years instead of 10 years.

  • Some brands also offer electric instant hot water systems for homes and businesses where gas can’t be used.

  • Some systems don't require electricity to operate for pilot light ignition, making them great for remote locations.

  • Lower heating requirements. Storage tank systems need to keep water at or above 60 degrees to prevent the growth of bacteria. Instant hot water systems only need to heat water to the desired temperature of around 50 degrees.

  • Energy efficiency. Some models have 7 star energy ratings.

  • Simple operation. System controllers can be placed at each point of use precise temperature control .

  • Instant water heaters have reduced maintenance requirements compared with hot water systems with a storage tank, which can leak or corrode.
