The ideal hot water system for your residential or commercial property is the one that suits your usage needs, energy requirements and budget – but with many options to choose from, how can you tell which one to install?
When choosing between heat pump hot water systems, solar panels and more, key factors for consideration include installation and maintenance costs, heating capacity, and the size of the system itself, and demand for energy efficient hot water systems is growing all the time.
In this blog, we’ll explore the different types of hot water systems and explain how to choose the right system for your property.
TL;DR
- The types of commercial and home hot water systems can be broadly divided into continuous flow and storage tank systems.
- There are also a variety of different models, including solar panels, electric, and heat pump models.
- The right choice for your home or business depends on several factors including available space, environmental constraints and budget.
Understanding Your Hot Water Needs
There’s no such thing as a one-size-fits-all hot water system – in fact, the right system for you will depend on how much hot water your household or business requires.
Broadly, the types of hot water systems boil down to two main categories: storage systems and continuous flow systems.
A continuous flow system uses instantaneous water heaters to make hot water accessible at any time, whereas storage systems store water in an insulated tank and heat it using a gas burner.
The majority of homeowners and businesses we see at D&S Plumbing opt for continuous flow systems over hot water storage tanks. It’s what we recommend to maximise energy efficiency and meet peak demand.
Having access to hot water when you want and need it is essential for a comfortable and convenient life. We’re proud to provide our clients with a reliable service.
Determining the best hot water system for your property requires consideration of the number of people using the system, peak usage times, and any specific requirements.
Types of Hot Water Systems
Whether you’re installing in a new build or upgrading an existing hot water system, there are several types of continuous flow and instantaneous systems to choose from. Here’s a rundown on the types of hot water systems available to you.
Solar Hot Water Systems
A solar hot water system works by collecting heat energy from the sun through rooftop panels and passing this heat directly onto the water flowing through. This heated water is then collected in hot water storage tanks and channelled directly to hot water taps.
Installing a solar water heater is highly beneficial for homeowners concerned with increasing energy efficiency, minimising environmental impact, and saving on their energy bills. In fact, solar hot water systems are ideal for those looking to reduce greenhouse gas emissions without compromising on minimum energy performance standards. In a similar vein, solar PV systems harness sunlight to generate electricity.
Before these benefits can be realised, the new hot water system must be installed – and before you commit to the installation, there are a few things you should know about solar hot water units.
Key considerations
- Initial installation cost. Solar hot water systems require a fairly significant initial investment to cover the cost of solar panels and a solar photovoltaic system.
- Roof space. Solar panels can require a lot of space on the roof, particularly for households and businesses that require
- Climate suitability. Solar hot water systems are ideal for warm climates that get plenty of sun and minimal cloud cover.
Solar hot water systems are ideal in situations with plenty of sun – and when energy from the sun is in short supply, a gas or electric booster helps to keep hot water heaters functioning.
Gas Hot Water Systems
Gas hot water systems use natural gas burners to heat water, either for storage or instantaneous heating as part of a continuous flow mechanism.
If you’re looking for a highly reliable, efficient water heater that saves energy and heats water quickly, gas systems are ideal.
Considering a gas hot water heater?
Key considerations
- Availability of natural gas. Natural gas hot water systems rely on natural gas reserves, a finite and limited resource at current consumption levels.
- Installation of gas lines. Transporting natural gas from gas storage systems requires the installation of pipes from the storage tank to the property.
- Safety measures. In contrast with solar water heaters, gas hot water systems introduce the threat of carbon monoxide poisoning if ventilation is improper.
Ultimately, gas hot water systems are ideal for any well-ventilated building where hot water outlets are in regular use.
Electric Hot Water Systems
Electric hot water systems heat water using an electric element and keep the hot water in a storage tank.
The perks of choosing an electric model include easy installation, availability, and lower upfront costs. Conventional electric water heaters are
Key considerations
- Running costs. Electric instantaneous water heaters are more expensive than gas systems, making them less attractive to those concerned with running costs.
- Energy efficiency. Electric hot water systems are less energy efficient than heat pump water heaters.
Electric hot water systems are ideal in situations where a smooth, efficient installation process is important.
Heat Pump Hot Water Systems
Heat pump hot water systems work by extracting heat from the surrounding air using electricity and transferring it into an insulated storage tank of cold water.
Heat pump hot water systems are popular for a number of reasons.
Key considerations
- Energy efficiency. The heat pump is ideal for those seeking the most energy-efficient hot water system Australia has to offer, as these use up to 70% less energy than electric hot water systems, making them more cost-effective and environmentally friendly.
- Cost savings. Beyond the immediate savings made possible by energy efficient operation, the government also offers incentives in the form of small-scale technology certificates, which aim to reduce greenhouse gas emissions.
Heat pump hot water systems are ideal for warmer climates, as cold areas may experience some performance issues. Due to higher upfront running costs, they’re also better for homes or businesses with more capital available.
Factors to Consider When Choosing a Hot Water System
Energy Efficiency and Environmental Impact
In terms of minimising energy bills and environmental impact long-term, the importance of energy efficiency cannot be understated. Comparing energy ratings is key to choosing the best hot water system for your property and for the environment.
Compared to other models, heat pump hot water systems are generally the most energy efficient on the market.
Space and Location Constraints
Some types of hot water systems require more space than others, particularly where hot water storage tanks are concerned.
Larger properties require hot water systems with larger storage water heaters and groups of solar panels, for example.
Location also influences the best hot water system for a property, which ultimately depends largely on the local climate and available space on the property. A system in the wrong place, particularly in the case of solar panels, may present challenges with water heating or heat loss.
Long-term Savings and Incentives
Installing a new hot water system in your home, whether it’s a continuous flow system or an electric storage water heater, is a great way to ensure you have access to the right water temperature for every activity in your home or business – even in cold climates.
Continuous flow water heaters, whether gas, solar or electric models, are generally more energy efficient than storage tanks, using a heat exchanger to heat water on demand and saving energy and money long-term.
There are also a variety of government incentives and rebates available for energy-efficient systems; for example, under the Queensland Business Energy Saving and Transformation Rebate, businesses can receive up to 50% back on purchase and installation costs.
Making the Right Choice for Your Needs
When choosing between all the types of hot water systems on the market, it’s crucial to consider the best options for your hot water usage needs, your budget, and the environment. Choosing the best hot water system for you will not only save you money but also negate unnecessary stress by keeping your water hot when it counts.
If you’re in the market for a new hot water system that will cut down energy bills and greenhouse gas emissions without compromising on the availability of hot water, this is a great opportunity to consult with professionals and explore water heating methods that will work for you.
