Instant Electric Hot Water Systems

Continuous hot water for the right low-demand application

Instant electric hot water systems heat water as it passes through the unit, so there's no tank sitting around and no fixed amount of hot water to run out of. They can be a useful option where hot water demand is very low and a compact system is what's needed.

Know the signs

Signs You Need a New Instant Electric Hot Water System

There are usually a few warning signs before an instant electric hot water system needs attention. Any one of these is worth getting checked before you're left with a cold shower and no warning.

01

No Hot Water at the Tap

If the unit isn't heating water as it passes through anymore, that's usually a sign something inside needs a closer look.

02

The Circuit Keeps Tripping

If the breaker trips repeatedly while the unit's running, that can point to the unit drawing more than the circuit's rated for, or a fault developing.

03

Water Temperature That Fluctuates

Water that runs hot then cold, or never quite gets there, usually means the unit isn't keeping up with demand.

04

The Unit's Getting On

Like any hot water system, instant electric units don't last forever. If yours has been in a while, it's worth having Andrew take a look before it fails outright.

Not quite ready for a new system?

If you're not sure whether it's time for a repair or a full replacement, Andrew can take a look and give you a straight answer either way.

Why Perth Hills Households Choose Instant Electric

Instant electric hot water systems tend to suit low-demand situations best, think a one-person household, a studio, a granny flat, or anywhere only one outlet is likely to be used at a time. For a typical family home, an electric storage system usually makes more sense, since it gives you a much bigger reserve of hot water for higher demand.

  • What we check first

Power, Switchboards and Older Homes

Larger instant units can draw a fair amount of power, and depending on the property, that might mean bigger electrical cables, a dedicated circuit, or some work to the switchboard, all of which we'll factor into your quote upfront. This is especially worth checking on older Perth Hills homes, where the existing electrical setup wasn't always designed with a high-demand instant unit in mind. We install and service instant electric systems from Rheem and Bosch, and Andrew can help you work out whether an instant system is the right fit, or whether an electric storage system with app-based controls would suit you better, particularly if you've got solar PV.

Not sure this is the right fit? Here’s how it stacks up against the other systems Andrew installs across the Hills:

  • Gas hot water systems: a gas storage system, suited to homes with a gas connection or bottled LPG already set up.
  • Electric hot water systems: a simple option that doesn’t require a gas connection.
  • Heat pump hot water systems: an energy-efficient alternative that draws heat from the air rather than generating it directly.
  • Instant gas hot water systems: heat water as you use it, without relying on a stored tank of hot water.
  • Hot water tank: a traditional storage setup that keeps a tank of hot water ready to use.

Instant Electric Hot Water Systems Across the Perth Hills

Instant electric works well in the right setting, but the property's electrical setup matters more here than with most hot water systems. Older homes around Kalamunda and Lesmurdie in particular weren't always wired with a high-demand instant unit in mind, so Andrew will check the existing installation and confirm what's needed before recommending instant electric over an electric storage system. Wherever you're based across the Hills, he'll walk you through what's involved for your specific property.
