FAQS

There are really two alternative ways of heating water for use in the home. It can either be heated in anticipation of use and then stored/kept hot in a hot water storage tank, which is located centrally within the property.

Alternatively, water can be heated on-demand for when it is required: a Continuous Flow Electric Water Heater heats water on-demand only when it is required.

When you turn on the hot water tap, the flow of the water starts the water heating process. When the tap is turned off, the water stops flowing, and the heating process stops.

A point-of-use water heater is a water heater that heats on-demand, but it is also physically small enough to be installed very close to where the hot water is used.

With a point-of-use water heater, hot water comes through the tap very quickly and there’s only a short time to wait.

Energy and water consumption is reduced because hot water does not need to flow through the pipes over long distances.

The MicroHeat Continuous Flow Electric Water Heater is ideally suited for installation as a point-of-use water heater, to provide instant hot water wherever it is needed.

  • It is 100% “optimised”, which means it will use only the precise amount of energy required to heat water to the desired temperature.
  • It can operate at very low flow rates – 1.5ltrs/min, which means both water and energy can be saved.

Yes. While Continuous Flow Electric Water Heaters are not new, the technology used in MicroHeat Continuous Flow Electric Water Heaters is new. It is this revolutionary new technology that delivers these additional features and benefits:

    • Optimise System

100% “optimisation” keeps the hot water temperature stable even if the cold water pressure drops. It also takes advantage of the incoming water temperature – the warmer the incoming water, the less energy is used to heat the water to the required temperature.

    • Small Physical Size

The small physical size and the fact that no heat is generated by the MicroHeat Continuous Flow Electric Water Heater allows the water heater to be installed in a small space at the point-of-use.

    • The hot water temperature is accurately maintained at the set temperature

This ranges between 20°C and a maximum of 50°C. The water temperature will not exceed 50°C

    • Low flow rate capability

The set temperature can be achieved with stability at very low flow rates – minimum 1.5 Litres per minute.

    • Low standby Energy Consumption

TVs can consume between 10W to 15W of energy while on standby – in contrast, the MicroHeat Continuous Flow Electric Water Heater will only consume 1W to 1.5W while in standby mode.

All MicroHeat Continuous Flow Electric Water Heaters come with a 3 year warranty.

Yes. Because it heats cold water “continuously” on-demand and does not rely on the storage of hot water.

Yes – provided the operational specifications are clearly understood and adhered to, and the MicroHeat Continuous Flow Electric Water Heater is installed correctly, as per the Installation Manual.

Yes. MicroHeat caters for differentiated centralised or point-of-use continuous flow water heating solutions.

Energy and water consumption related to hot water is dependent on individual usage patterns. However, if a point-of-use hot water service using a MicroHeat Continuous Flow Electric Water Heater is installed, energy and water consumption losses incurred by the hot water reticulation (pipes) will be significantly reduced.

An average hot water reticulation, with a total length of 60m, can conservatively lose 2.5kW-hr/day. That’s the equivalent of 900kW-hr per annum, if used only once per day – and this amounts to approximately $215 per annum.

Running hot water, waiting for it to reach the tap at the desired temperature, can waste up to 7.5ltrs/day. Even if used only once per day, this equates to approximately 2,750ltrs of water wasted per annum.

Keep in mind that household heating, including water heating, accounts for approximately 30% of all domestic running costs – the MicroHeat Continuous Flow Electric Water Heater can help to reduce these costs.

Yes – however, to ensure the most effective solution is supplied for individual requirements, we recommend a consultation with our technical team to discuss the multiple options available to deliver the optimum benefits and savings when delivering hot water throughout your home.

In certain situations, replacing an old electric hot water system with any electric water heating service is no longer an option. Government regulations now restrict the installation of electric hot water services in certain classes of building.

Electric Hot Water Services cannot be installed in any new single story, detached, terrace or town house, or any such existing property, where there is access to piped natural gas. (Some exemptions apply – in Victoria, electric hot water services may be installed if a rain water tank is also installed).

Electric Hot Water Services can be installed in apartments or multi-story constructions and can be installed into any construction where gas, solar or heat pump water heating options are not feasible.

The MicroHeat Continuous Flow Electric Water Heater is designed to work with drinking water, but will not operate effectively with rain water. However, its operation or service longevity is not affected by water hardness.MicroHeat Continuous Flow Electric Water Heaters that need to operate with water outside the normal drinking water range can be provided.

The ability to heat water dynamically while it is flowing is directly related to the flow rate of the water, and the increase in cold water temperature required. Thus the heating ability will be dependent on the electrical power supplied that may be inadequate, and may need to be upgraded.

MicroHeat caters for centralised or point-of-use continuous flow water heating solutions. In either instance, we recommend a consultation with our technical team to discuss the various options and opportunities for energy and water savings.

MicroHeat Continuous Flow Electric Water Heaters are competitively priced and, when installed at the point-of-use, this eliminates the need for costly hot water plumbing reticulation (piping).

Tempering valves – used in most traditional hot water service installations – are not required – this also achieves a reduction in cost.

Installation must be performed by a qualified electrician and a qualified plumber – prices vary per installer.

The overall cost of installation depends on:

  • Electrical power capability of the establishment
  • Proposed/existing plumbing arrangements
  • Accessibility at the selected installation site

The MicroHeat Continuous Flow Electric Water Heater must be electrically hard wired to the switchboard.

No – a MicroHeat Continuous Flow Electric Water Heater must be electrically hard wired to the switchboard. Please consult our technical team or an electrician for details on electrical wiring requirements.
