The benefits of 3 phase electric continuous flow hot water systems
- Systems are engineered to ensure you’ll never run out of hot water. This is because they heat the water as you use it
- Accurate digital temperature displays and control for safety.
- User comfort with adjustable outlet temperatures and continuous hot water flow.
- Energy efficiency, because they do not store hot water and do not need to keep water hot for long periods.
- Suitable for both infrequent and frequent hot water demand.
- Because they do not need to store hot water their compact size means they require very little space.
- Ideal for residential apartments and commercial buildings.
- No tempering valve required on 50℃ models in residential applications.
The disadvantages of 3 phase electric continuous flow hot water systems
- Require existing 415 Volt 3 phase power. Many houses and apartments are typically wired with 240 Volt single phase power and it is hyper expensive to retrofit 415 Volt 3 phase power into existing buildings.
- Low flow rates mean they can only provide enough hot water for single point usage at one time.
- Water temperatures are limited to a maximum of 50℃ and 60℃ depending on the model.
- Experience suggests they have a shorter life than gas continuous flow, solar hot water, and standard electric hot water systems. However, the new Rheem Eclipse and Rinnai Efinity models may last longer than the Steibel Eltron DEL, DHB and DHE models.

Instant instantaneous continuous flow electric hot water system Facts
These systems are not very common and generally require a lot of energy to operate. They were originally designed as bath heaters and sink heaters and were connected to a 415 volt ( 3 Phase ) power supply. It is likely that you will now find them in unit complexes where space is limited.
As most houses only have a 240 volt power supply it is not economical to retrofit an instant electric hot water system as a replacement for another type of hot water system. Before asking for a quote to change to instant electric hot water check to see if you have a 415 volt ( 3 Phase ) power supply.
An alternative may be a boiling water unit, – an Instant Gas Hot water System or a small under sink electric storage Hot Water System.
Older systems are not very good at controlling the temperature of the hot water. they produce. The more you turn the water on the cooler the water it is likely to get. The newer models are much more advanced and can deliver hot water at constant temperatures regardless of flow rates
