Frequently asked questions

Do you have more burning questions about leaking taps, a blocked toilet or your plumbing system? Here are some plumbing solutions.

What is the most efficient electric hot water system?

The most efficient traditional electric hot water systems are well-insulated storage tanks paired with off-peak or controlled load tariffs. For maximum efficiency overall, heat pump systems outperform standard electric tanks, but within purely electric systems, correct sizing and modern insulation make the biggest difference.

Efficiency isn’t just about the unit, it’s about matching the system to your household’s usage.

What is the cheapest way to heat water with electricity?

Using electricity on off-peak or controlled load tariffs is often the cheapest way to heat water with a standard electric system. These systems heat water overnight when electricity rates are lower and store it for use during the day.

The key is ensuring the tank is correctly sized so you don’t run out of hot water before it reheats.

Is there an electric instant hot water system?

Yes – electric instant (tankless) hot water systems are available. They heat water on demand rather than storing it in a tank.

However, they require significant electrical capacity and are often better suited to single outlets or smaller households. A professional assessment is essential to determine whether your home’s electrical supply can support one.

What size electric hot water system for 2 people?

For two people, many Sydney homes are well suited to a 125–160 litre electric storage system, depending on shower habits and peak usage times.

Oversizing wastes energy, while undersizing leads to running out of hot water. Correct sizing ensures comfort and efficiency.

Do electric hot water systems use a lot of power?

Hot water is one of the biggest contributors to household electricity use. Electric systems can use significant power, especially if they’re older, poorly insulated, or incorrectly sized.

Modern systems with proper insulation, efficient elements, and off-peak operation help manage energy use more effectively.

What do plumbers say about tankless water heaters?

Tankless (instant) systems can be effective in the right setting, but plumbers often caution that they’re not suitable for every home. Electrical capacity, usage patterns, and installation costs all need to be considered.

For many households, a correctly sized storage system offers more consistent performance with fewer electrical upgrades.

What runs up the electric bill the most?

Heating water is consistently one of the largest contributors to electricity bills, alongside heating, cooling, and older appliances. Inefficient hot water systems can quietly drive up costs over time.

What is the life expectancy of an electric hot water system?

Most electric hot water systems last 10–15 years, depending on water quality, usage, and maintenance. Regular servicing and correct installation can help extend lifespan and maintain efficiency.
