How Does Water Heating Work?


An electric hot water heater is an instant water heater that can be fitted to any plumbing appliances in your home, from sinks to baths and showers. Unlike gas water heaters, an electric hot water heater doesn’t require additional piping or ventilation, making installation more straightforward.

What Size Water Heater Do I Need?


Every home will require a different size water heater, depending on your hot water usage. As a guide, allow an average of 30-50 litres per person when working out which water heater will best suit you. Installing an electric instant water heater can be a cost-effective and energy-efficient investment for any home.
