Save on space and running costs
An instantaneous electric HWS provides hot water on demand without the use of a storage tank. They work best when the HWS is positioned close to the point of use. The water flows through the hot water system and is heated as it's needed for use. As energy is only used when the tap is turned on, you'll benefit from energy savings and lower running costs.
This tankless HWS does not use gas, and whole-home models require 3-phase power to run; this makes it suitable for modern residential apartments and commercial properties. They are the premier choice for places with limited space, as their compact design allows them to be stored seamlessly in a cupboard. Additionally, their lack of a tank reduces the risk of water damage from leakages. By choosing electric continuous-flow hot water, you can easily save space without compromising performance.
Continuous-Flow Gas
Instantaneous gas systems heat water on demand, in the same way as their electric counterparts, but feature a gas burner instead. Turning on the taps triggers the heat exchanger to heat water as it runs through it.
Continuous-Flow Electric
Electric continuous-flow systems heat water on demand, making it more energy-efficient than a storage system. We recommend these systems for households or businesses in high-density areas, as they are a compact, space-saving option.
Electric Hot Water Tank Systems
Electric storage systems heat and store water for daily use. Storage tank options commonly range from 80L to 400L, depending on household needs. Households can choose to set up their HWS to run during off-peak hours for lower running costs.
Gas Hot Water Tank Systems
Gas hot water tanks store hot water for use throughout the day. As stored water is drawn from the tank, it is automatically replaced with water that is heated back to a set temperature. These systems can also be set up with LPG or conversion kits to provide reliable hot water access to off-grid homes.
Heat Pump Water Heater
Heat pump hot water systems are energy-efficient because they extract heat from the ambient air and use it to heat water. The Victorian government largely incentivises these HWS, with rebate support available to help lower upfront costs for eligible households.
Solar Hot Water Units
A solar hot water system captures sunlight to heat water circulating through solar collector panels on the roof. After the water is heated, it is transferred into a highly insulated tank. These systems require a booster to operate during high-usage periods or on cloudy days to ensure reliable hot water.
FAQs on instant electric hot water systems
Have electric instantaneous hot water systems got you feeling overwhelmed or left scratching your head? Our licenced plumbers have answered these FAQs to put your mind at ease.
Do I need to have 3-phase power for my electric continuous-flow HWS to work?
Not always, but if you're looking to install a whole-house electric continuous-flow system, you will need to have access to 3-phase power. Smaller, single-outlet systems can run on single-phase power, but they supply hot water to only one tap at a low flow rate, such as a hand basin. For whole-home supply, 3-phase is recommended because it distributes electrical demand across three wires, delivering hot water at a high flow rate. When our plumbers come to your property to install an HWS, we will thoroughly inspect your existing setup and ensure it has sufficient capacity for an electric continuous-flow unit.
Is it normal for it to take a couple of seconds for my electric continuous-flow hot water system to kick in?
Yes, as electric continuous-flow hot water systems do not have hot water stored in a tank, there are often a few seconds between turning on the tap and hot water running through. This is because the moving water triggers the internal heating element to activate. If your water is running cold for a prolonged period of time, it's best to book in a service, as this could mean a failed heating element, faulty flow sensor, or tripped circuit breaker.
What's the typical lifespan of an electric continuous-flow hot water system in Melbourne?
Electric instantaneous systems typically last around 15 years in Melbourne. Melbourne water is relatively soft and low in minerals, which reduces scaling on heating elements. Routine services, such as valve, filter, and electrical connection checks, ensure your HWS is working optimally and help prolong its lifespan. Outright Plumbing offers a range of services to help maintain your electric continuous-flow hot water system and ensure reliable hot water year-round.
