Heat Pump Hot Water Systems

Heat pump units extract heat from the surrounding air to warm water, using considerably less electricity than a conventional electric storage system. They suit most Australian climates, install outdoors or in ventilated indoor spaces, and qualify for STC rebates that reduce upfront costs.

instantaneous gas hot water system installed by Tempco FRH Energy

Instantaneous Gas Hot Water

Instantaneous gas hot water systems heat water on demand as it flows through the unit, with no storage tank required. Also known as continuous flow systems, they deliver a consistent supply regardless of how much hot water has already been used, well suited to larger households or homes where back-to-back showers and simultaneous draws are common.

hydronic hot water heating system in a home installed by Tempco FRH Energy

Hydronic Hot Water Heating

Hydronic systems circulate heated water through radiators, towel rails, or underfloor pipework for whole-home warmth alongside domestic hot water supply. They run on gas or heat pump sources and suit households in cooler climates looking for an integrated heating solution.

How to choose

Choosing the Right Hot Water System for Your Home

Storage or continuous flow, rebate eligibility, and matching the system to your household.

Storage Tank vs Continuous Flow

Storage hot water systems hold a set volume of heated water ready for use, with tank size and element rating determining how quickly the system recovers between draws. Continuous flow systems heat water on demand with no storage, making them a compact option for homes with limited space or moderate, spread-out usage.

Off-Peak Tariffs and Rebate Eligibility

Electric storage hot water systems configured on an off-peak tariff heat water during lower-rate overnight periods, keeping daily running costs down without changing how hot water is used. Heat pump systems qualify for Small-Scale Technology Certificates (STCs), a government incentive that offsets installation costs based on the system's rated output and location across Australia.

Matching the System to Your Household

Household size and existing energy connections are the main factors in selecting the right hot water unit. Smaller households on electricity typically suit a heat pump or off-peak electric storage system. Larger households with natural gas connected often benefit from a continuous flow gas system, which handles back-to-back demand without a storage tank. If you're weighing up the two most efficient options, our guide on heat pump vs solar hot water covers the key differences in cost, performance, and suitability.

Installation & costs

Hot Water System Installation and Running Costs

All hot water system installations require a licensed plumber for water connections and, where electrical work is involved, a licensed electrician. Tempco FRH Energy manages supply and installation as a single service including system sizing, plumbing connections, electrical setup, and tariff configuration all handled together.

Running costs vary by system type and usage. Heat pump hot water systems cost less to run than standard electric storage systems. Gas remains competitive for households already on natural gas, particularly with a continuous flow unit sized to actual peak demand.

Frequently Asked Questions

What is the best brand of hot water system in Australia?

Well-regarded brands available across Australia include Reclaim Energy, Daikin, Rinnai, and Apricus, covering heat pump, gas, and electric options. The right brand depends on system type and household requirements. Tempco can advise on suitable options during consultation.

What is the most energy-efficient hot water system for an Australian home?

Heat pump hot water systems are the most energy-efficient option. Heat pumps use considerably less electricity than standard electric storage systems.

What size hot water unit do I need?

Household size and peak usage patterns are the main factors. Smaller households suit lower-capacity storage tanks; larger households need higher capacity with faster recovery. A licensed plumber can confirm the right sizing based on your daily demand before installation.

Can I get a rebate on a new hot water system in Australia?

Heat pump systems qualify for Small-Scale Technology Certificates (STCs) under Australia's renewable energy scheme. The rebate value depends on your location and the system's rated output. Tempco can confirm STC eligibility and applicable rebates before you buy.

What is the difference between a storage and an instantaneous hot water system?

Storage systems heat and hold water in an insulated tank ready for use. Instantaneous systems heat water on demand as it flows through the unit, with no storage tank involved. Continuous flow gas systems are the most common instantaneous option and suit households with consistent, moderate usage patterns.

Do I need a plumber to install a hot water system?

Yes. All installations require a licensed plumber for water connections and a licensed electrician where electrical supply is involved. Tempco FRH Energy provides combined supply and installation, covering compliant connections, correct sizing, and tariff setup in one service.
